Perfect Corn Muffins with Cheese and Jalapeno - Duration: 6:55.

Check out these corn muffins jalapeno corn muffins with actual corn

in them so they are SuperDuper flavorful and delicious so where are they this

doesn't look like a helping of corn muffins... that's right and let's be really

clear people who love corn muffins they like what they like these

are gonna have several ingredients in them so if you're a purist and you're

like I just want cornbread! cornmeal! flour! ...this has got a little more in it a

little bit of spice to 'em a little kick okay so we're just gonna mix some dry

ingredients together ... we've got some flour we're gonna have the full

recipe down below and at MyFoodChannel dot com ... this happens to be

all-purpose flour then we're gonna add some cornmeal this

is medium ground and then we've got some baking powder to help it rise, and I'm adding

just a smidge of salt and then we're adding some seasoning got a little

Chipotle and a little bit of smoked paprika and that's it for the dry

ingredients then we're just gonna mix that together and that's all we're gonna

do to the dry ingredients now let's mix together some pizzazz to add to it so

we're gonna start with an egg I like to just give it a little whisk even though

we're gonna mix it all together gonna add some milk for a little

creaminess some oil you can add butter if you need to we are gonna add some

honey some people are like "NO sweetner in my corn bread!" we're gonna mix this

around I like to add corn to my cornbread it adds a little bit of

moisture without having to add any more oil or milk and then also a little bit

of minced onion now this is chef buck so we need spicy these are pickled jalapenos

they're just roughly chopped we're gonna add those babies in there you've got

some milk but we're gonna add some cheese now that looks like a nuclear

power plant orange cheese well it is a sharp cheddar I'm gonna add about a cup

is that actual cheese or just the shredded vest of a crossing guard?

I like a strong cheese especially when I'm adding something with a little bit

of spice I like to have a cheese with a little bit of a bite so now we'll

mix this stuff together so we've got this mixed together we'll

add it all at once into our dry

and then you just want to stir it until the dry ingredients are

moistened you do not want to over mix cornbread mixtures but you do want to

make sure you get that baking powder and your seasonings mixed throughout

that looks really tasty doesn't it

it may not look great but it smells great ...kind of looks like 2:00 a.m. at

the Abbey Bar.... oh, all right you don't get to have any....so you see we have

no more powder it's all mixed together so we're gonna get them in the muffin

tins and get it in the oven... all right so this batter is thick so

what I use is just like a measuring cup and you just want to evenly spread it

between your muffin tins and you can fill these all the way to the top

they're not gonna make a big mess in the oven for you

hold on I gotta do my Martin Scorsese tracking shot...okay that's a

great idea but you'll see I don't have any powder which means I did mix it up

well ... if you see any dry mix you can sort of just

push it together ... this recipe is gonna make

about 12 medium sized corn muffins and you can use the same batter for minis

and just cook it less or you put it in a skillet and cook it more... you want

them pretty even so if you find okay really these aren't even just move a

little bit from one to another but again the batter is pretty forgiving now we're

gonna place some fresh jalapeno slices on the top this is definitely optional

but it makes them look really nice when they come back out of the oven they've

risen a little bit and you've got these little rings on the top it looks

fantastic ...this ain't optional if you're making jalapeno corn muffins you got

to do this you'd be crazy not to especially for chef buck because you know

chef buck likes his spice... they look really fancy pants with the

jalapeno on top again it's up to you

and if you have a little bit of extra cheese you know who doesn't like

cheese we like this with stews and barbecue and things like that but also

for breakfast ....we like some savory muffins in

the morning for breakfast with eggs all

right these are ready to go in the oven ...we'll be back in a minute

oh yeah...these look fantastic just to be sure we're gonna

use a toothpick if you don't have a toothpick a knife will do

you're just gonna stick it all the way down bring it up now you have cheese and

things in here so it's not gonna be perfect

but there's not a bunch of goo a lot of batter sticking to it

having them in the oven for a half hour that's quite a long time

and when you have wet ingredients like that corn and the jalapenos in there it

needs a little more cooking time because you don't want it to be

sopping wet which can happen if you have a lot of veggies that you're putting in

your muffin so we're gonna give them five minutes just to cool

and then we're gonna taste them

check out these corn muffins jalapeno corn muffins with actual corn

in them so they are SuperDuper flavorful and delicious

look at those chunky monkeys see that chunks of corn in there and there's

jalapeno inside too not just on the decorative top but they look fantastic

they taste delisioso...you snuck a bite?

I couldn't wait cause I started eating my chili ...Camera Girl

made a batch the other day that we had in the morning for breakfast with

scrambled eggs I mean these are great any time and because they have corn in

them they're moist .... they're just not dry Gobi Desert

Lawrence of Arabia corn muffins... you don't have to put jalapeno in it but

you do have to

if you want to print the recipe

Don't Ignore These Early Symptoms of Gout - Duration: 13:23.

Ten common symptoms of gout

Gout is a painful condition that is seeing a resurgence of sufferers

This uncomfortable affliction is a form of arthritis

often called gouty arthritis gout

Can affect anyone but it is most common with people over the age of 30 it is more common in men than women

The causes of God are mainly diet-related

The condition is caused by high levels of uric acid in the body which collects in the joints and can cause pain

People often ignore the warning signs of count until the problem becomes severe

it is important to be aware of these signs as addressing the problem early can save you from future complications if

You have multiple signs and symptoms of gout ask your doctor to check your health levels and get the best treatment for gout

Here are the early warning signs of count

1

joint pain

the most common symptom of gout is intense pain in the joint areas in

Many cases the first attack occurs with sharp aches in the big toe the pain could also occur in the feet ankles

hands wrists or knees

the attack often occurs in the middle of the night with the pain lasting for anywhere between 4 to 12 hours

Once the pain subsides there is chance of recurrence though hardly ever before a few months

With time if the condition intensifies these attacks become more frequent and the pain much harsher

In fact the aches may begin to occur simultaneously and more than one joint as well

-

swelling

before we continue this video do not forget to subscribe my channel to see if they're useful health videos as

Your big toe joint is the area largely affected by gout and uric acid buildup your body may react with massive inflammation

It's not uncommon for the area around the joint to become very swollen

again because gout pain can extend from the big toe to the foot and

Travel all the way up the calf and shin to the knee

Swelling may also extend past the affected area to the entire limb of the lower

leg if one or both of your big toes is affected by gout the entire foot and leg may become inflamed red and

painful

Touching the swollen areas may be very painful as well

But you can relieve some of the discomfort by applying cold compresses directly to the inflamed areas

3

tophi formation in

Cases where gut remains untreated over a long period of time tophi formation takes place in the joint area

Tophi are basically chalky formations of uric acid which develop in the soft tissue of a GAD prone joint

These tophi are found very close to the surface of the skin with the overlaying layer off and turning reddish as a consequence on

remaining unchecked OFI formation can spread and affect cartilage and cause much damage

currently

Advances in medicine have made this condition rather uncommon and incident mostly in cases of absolute neglect it

Is nonetheless of utmost importance that long-term medication for God Prevention be sought by patients

For

stiffness of joints

affected joints experience decreased mobility in the aftermath of a gout attack

For the most part, this is because of the residual symptoms such as the lingering aches and swelling or tenderness

The discomfort makes it more taxing to move the affected area

That's causing patients to willfully suspend movement

however in cases where God remains largely unchecked in progresses over time

Affected joint tend to be Steff

The range of the movement reduces gradually such that over time it is possible that those joints may exhibit very little mobility

Six-night pain a

Common time for gout pain to strike is in the middle of the night you may go to bed feeling great

But wake up in a start because your toe joints or feet are killing you because you suffered from a gout attack overnight

it's obviously very difficult to sleep soundly or stay sleeping when you're dealing with gout pain if

You are in the midst of a gout attack

Even pressure from crossing your legs or constricting them in a sleep position can exaggerate pain

If you sleep with a spouse or pet slight contact and even the weight of your sheets can become unbearable

You can be bedridden for a few days if walking and standing is painful

However often the pain of lying in bed can be severe

9

fever

Gout may start affecting only one joint, but it may soon move to multiple areas throughout the body

When gout Sprint's to multiple areas of the body?

Doctors refer to it as polyarticular gout due to the inflammatory nature of the condition

with the development of polio ticular gout fever is a common symptom and

Patients will typically describe the onset of a fever that is typically low-grade which is common with massive gout inflammation

other polyarticular gout symptoms in addition to a low-grade fever

Signs of vitamin b12 deficiency

Vitamin b12 is vital for the formation of red blood cells that carry oxygen around the body it

Is also needed for the proper

Functioning and health of nerve tissue as it is involved in producing the protective myelin sheath that covers the nerves and conducts nerve impulses

It works together with faux lead in the metabolism of cells especially affecting DNA synthesis and fatty acid and amino acid metabolism

People often ignore the warning signs of vitamin b12 deficiency

Until the problem becomes severe it is important to be aware of these signs as addressing the problem early can save you from future complications

If you have multiple signs and symptoms of vitamin b12 deficiency

Ask your doctor to check your health levels and get the best treatment for vitamin b12 deficiency

Here are the early warning signs of vitamin b12 deficiency

One

fatigue and low energy this vitamin plays a prominent role in energy metabolism

Hence its deficiency has a direct impact on your energy and endurance levels

Vitamin b12 enhances your body's ability to make DNA for new cells to provide energy

It is also needed to form healthy red blood cells that carry oxygen to the whole body

Without proper oxygen levels you feel tired and lethargic

Plus b12 is needed to turn the food you eat into energy to power your metabolism

Low metabolism prevents you from feeling your best in performing at your highest energy level

Numbness and tingling sensations

Before we continue this video do not forget to subscribe my channel to see if they're useful health videos

Vitamin b12 plays a key role in keeping your nervous system healthy

thus

Neurological signs like numbness or a tingling sensation in the hands and feet can indicate its deficiency

Vitamin b12 helps in the manufacturing of nerves and moreover it has a key role in helping oxygen reach different parts of the body

For oxygen supply is one of the main causes of numbness and tingling sensations

it's deficiency can also cause balance problems a

1991 study published in medicine highlights the effect of cobalamin deficiency in the nervous system

Which causes loss of contain ease sensation muscle weakness diminished or hyperactive reflexes?

spasticity and urinary or fecal incontinence

to name a few

Three

loss of muscle strength

Things happen everyday that can cause a person to lose the feeling of strength in the muscles

You can take on a more demanding schedule at work, or you can start a vigorous new workout program

However, if you are finding it hard to bring in the groceries after a trip to the store

Then there could be an underlying reason why your muscles are not performing in the way that they typically do

When a lack of vitamin b12 is constricting the amount of oxygen in your red blood cells

Then this can affect your muscle strength to varying degrees

For

low blood pressure

Deficiencies of vitamin b12 and folic acid can cause anemia which can lead to low blood pressure also known as hypotension

vitamin b12 helps your body produce red blood cells so that adequate oxygen reaches each and every part of your body including the heart a

2012 study published in a Texas Heart Institute Journal reports that vitamin b12 deficiency is well known among neurologists

But is often overlooked by

Cardiologists when treating low blood pressure if you suffer from low blood pressure up for a b12 test

Even moderate forms of low blood pressure can cause shortness of breath dizziness weakness

fainting and risk of injury from Falls, but

5

forgetfulness

Everyone tends to be a little forgetful at times especially

If a person is going through a particularly stressful time at home or work, or if there is a big event coming up soon

however when this becomes the norm it may be time to have your blood tested for a b12 deficiency as

with most early warning symptoms of a b12 deficiency

The lack of oxygen in the red blood cells

Specifically those gone to the brain are usually to blame for the sudden forgetfulness

However some patients jump to worrying that this could be the early onset of much more severe conditions

Such as dementia or Alzheimer's when it is simply the lack of enough vitamin b12 in the body

6

skin lesions

low vitamin b12 can also cause skin lesions and hair changes a

2008 study published in Canadian Family Physicians reports that vitamin b12 deficiencies linked to skin lesions

unexplained and non resolving skin lesions can signal vitamin b12 deficiency

Hence you need to visit your doctor as soon as possible

along with skin lesions its deficiency can cause hyperpigmentation of the skin

Which leads to uneven skin color and dark patches on the skin?

7

Changes in the tongue all healthy people have little bumps across the surface of their tongues often refer to as papillae

usually

Approximately 50% of patients suffering from a vitamin b12 deficiency may seem to lose these bumps on their tongues

especially around the edges

Some patients also report that they experienced a soreness along the back side of the tongue and even occasionally a burning sensation

These papillae also contain taste buds and this may all secrete problems in the way that some foods may taste as well

However, this is only temporary and everything should return to normal once there are enough vitamin b12 in the body

8

depression this particular B vitamin is also essential for mental health

Its role in forming red blood cells in turn helps support a healthy nervous system

plus it helps lower the level of homocysteine a byproduct of protein metabolism a

High level of homocysteine in the body can lead to depression

This is why it is important to consider the possibility of b12 deficiency especially among the elderly suffering from depression

according to a 2009 study published in the Journal of Clinical psychiatry emphasis upon in fact a

2013 study published in the open Neurology Journal shed light on the importance of vitamin b12

supplementation in the treatment of major depressive disorder

This study found that people with depression

Experienced significant improvement in symptoms when treated with vitamin b12 supplementation as well as antidepressants

New Walking Indoraptor Vs Mosasaurus Unboxing Jurassic World Mattel Dinosaur Toys Imaginext - Duration: 11:37.

oh good keep watching it's in the Raptor verse pull the swords in a battle to the

New Walking Indoraptor Vs Mosasaurus Unboxing Jurassic World Mattel Dinosaur Toys Imaginext

good nothing stop the Raptor it's about to eat oh it is this the end of Jurassic

world

okay it's great to see you again I got an awesome toy today this is the

Imaginext walking in director I know what you're thinking you hear Imaginext

you think little toys for little kids this is awesome okay it is for ages 3 to

8 but it's cool because there's an infrared sensor the interrupter follows

the ATV so that is really cool he chases it it comes with an O and I come okay

you can make it run but just by turning that thing but ah let's check out the

back it says what you do if there's an angry dinosaur chasing you drive away as

fast as you can that's what Owens trying to do it is a TV but the faster he goes

the faster this genetically-altered interrupter chases him the raptors of

Jurassic world have a new outlaw let the adventure begin

okay so press down an O n in the power pad to hear the Dino roar drive away

from the Dino to trigger the action turn power pad Dino starts walking on its own

fold on ramp for a quick getaway awesome says it uses six AAA batteries okay

let's go ahead and open this up okay so let's go ahead and free him from the

package and it is a him odd they did

they did say the interrupter is all him so it's definitely a male okay guys here

we have the set up open is totally hilarious you have Owen on

the ATV this has an infrared sensor so as Owen starts to get away it chases him

and the faster Owen goes the faster the interactor goes that is hilarious it

almost looks like the in director is riding a bike check this off so if you

pull one away a distance it's got to be a straight line of sight see he is

chasing Owen now how funny is that now he's pushing Owen

I'm keeping the ATV closed this guy's tried to run off my table for them once

already okay so if you want you could take Owen he fits on a slot right there

on the in directors back and if you push him down then director opens his mouth

anteye roars but of course all the sound comes out of this song box that is

attached to him I don't really like the fact they attached the song box but you

know I understand I mean this is made more geared toward younger children and

not that much toward collectors I mean Imaginext is more I guess fun play boy

you know it looks really cool if you look at the eye I mean that it's a glass

looking eye a really cool red evil-looking hi you open the mouth I

mean they did a great job texturing and painting the tongue the individual teeth

on this so you know even though it's geared for younger children it looks

really cool you got all the spikes on its neck the arms do move up and down

and they are the size that they could grab Owen so it could grab Owen off of

his ATV there and hold on to him so like I said the arms move up and down the

legs are oh there we go the legs are attached and they go around

in a circle when it's chasing the ATV let's take another look

and he will keep chasing it I'll show you in a little bit but big this I guess

this would be like the third claw so he really just has two claws

so the are the legs just go round and round there like I said I think it's

gonna be on the ground to activate it doesn't seem like he wants to work if

it's not on the ground so once again looks like he's whoa there he goes now

he was pushing the ATV so he's got this trailer on the back to take the ATV

place it on the trailer the ramp goes up and down so the ATV could drive away I

don't know why this guy just took off

activate the sensor in the back to when the ATV gets a certain distance it takes

off so the inter raptor is running from the ATV right now okay I will put the

ATV right there so it doesn't run anywhere and then you can see the back

of it this side I mean it looks kind of goofy with that big you know the big

block attached but I guess I believe it uses six double-a batteries and then I

think two double-a batteries in the ATV so anyways I'm gonna shut this guy down

for a minute so he doesn't run away because he will run off of my table here

we got Owen so Owens got tiny little mustache I mean he looked

don't like the mustache arms move up and down 360 legs move the ATV is cool it's

a nice great little green ATV with bars in the front and then Owen does fit on

it and he could pull the handlebars so it looks more realistic and then you're

just gonna this guy's gonna he will chase Owen and when he gets up to him he

just grabs Owen right out of the ATV in

serious trouble

let's hear the roar from this side so it is it is a really cool sounding nor too

Fun with Arches - Duration: 5:45.

Arches have lots of fun properties.

For example, even though they look like curved beams,

they carry load a completely different way.

Beams carry load by bending,

and this one cannot even support the weight of two wood blocks.

This curved beam also works by bending,

and despite being curved like an arch,

it still cannot support the weight of two blocks.

However, if we support the ends of this curved structure

so that it can carry compression,

it can suddenly can support two blocks, with ease.

If the curved shape is cut into pieces,

no meaningful bending is transferred

from one block to the next.

Instead, the blocks can only transfer compression to their neighbours.

If we reconstitute the arch,

only compression is transferred from one block to the next,

and yet the arch is still able to carry two wood blocks.

To further prove that no bending is transferred from block to the next,

we can put a roller between any pair of adjacent blocks,

and the arch still stands.

Isn't that cool!

To better understand how an arch gets its strength,

consider a piece of cloth.

It cannot even support itself.

However, if we allow it to take a curved shape like this,

it can carry a substantial amount of load.

And it does that because tension flows along its curved shape.

Arches work the same as this hammock,

except that their shape is reflected upside-down,

and they carry compression rather than tension.

Another popular misconception about arches is that they need a keystone.

By a keystone, we mean a tapered stone at the top of the arch.

Our model arch was purposely made with an even number of segments

so that there is nothing in it that could be construed to be a keystone.

Here's another fun thing:

Did you know that some arches will collapse if load is REMOVED?

Just like a teeter-totter,

arches require the forces acting on them

to be suitably balanced.

For example, this arch can carry heavy loads if they are suitably balanced.

However, if we remove any one of the loads,

the arch fails catastrophically.

It's a little tricky to explain why this happens.

Our "Arches and Chains" video shows that for an

arch to stand,

its corresponding chain system, when reflected,

must lie inside the profile of the arch.

Here is the chain system corresponding to the original arch.

The chain and weights have been chosen

so that their weights are proportional, respectively,

to the weights of the arch itself and

the containers of marbles.

It is thus a true representation of the arch.

As you can see, this arch passes this so-called "chain test".

If we remove one of the side weights,

the new chain shape does not lie inside the arch profile,

and the chain test fails.

When we remove the corresponding load from the arch,

it does indeed fall down.

Can you picture how the chain will change shape if the middle weight is removed?

Will the arch stand or fall?

Removing the middle weight produces a chain shape

that falls outside of the arch profile,

and the corresponding arch collapses.

You might be curious how this arch,

from our other video, can stand.

It is easy to show that this arch passes the chain test,

and that is why it stands.

If we now add weights proportional to the external load,

the arch passes this modified chain test,

and that is why it can still stand.

And, here's one last thing:

Many people think that a semicircle is a good shape for an arch,

and sometimes it can be.

However, thin semicircular arches, like this one,

fail the chain test and fall down.

To learn why they can still sometimes be used,

you will have to watch our other video.

Thanks for watching.
