we wanted to find out all the differences

between M&M's in the UK and the US.

This is "Food Wars."

Here in the US, we have eight

different portion sizes of M&M's.

All the way at the end here,

the smallest portion is known as the fun size.

This little guy is 0.6 ounces, or 18 grams.

Then, single size bag, 1.69 ounces.

Then we go up to the box.

This is 3.1 ounces, or 87 grams.

Now we have the share size.

Peanut makes its first appearance.

This is 3.27 ounces, or 92.7 grams.

Little bigger of a pouch,

we have the 10.7-ounce, or 303-gram,

sharing-size pouch part two.

Then we jump up to the family size.

This is 19.2 ounces, 545 grams.

Throwing a party? M&M's got you covered.

This is the party pack.

38 ounces, 1,105 grams.

And the biggest portion size you can get is this,

the pantry-size tub.

62 ounces, 1,757 grams.

In the UK, M&M's come in four standard portion sizes.

Around the holidays, you can get a selection box

with a small packet of M&M's that weighs 45 grams,

but unfortunately, we couldn't get one today.

Our standard pouch is 125 grams.

Then we move up to a more-to-share bag,

which, for standard chocolate M&M's, comes with 250 grams.

The largest size available in the UK is a party bag.

I went to about eight different supermarkets

and I couldn't find one,

but usually they would contain 1 kilogram of M&M's,

so we're going to make our own.

There is our unofficial party-size bag.

1 kilogram of M&M's.

All said, America's largest size

is 75.7% larger than the UK's.

In the UK, the portion sizes also vary slightly

depending on which flavor of M&M's you've opted for.

A more-to-share bag of chocolate M&M's is 250 grams,

but a more-to-share bag of crispy M&M's is just 246 grams.

If you want the most value in the UK,

opt for peanut M&M's.

A more-to-share bag of those contains 268 grams.

Are the M&M's themselves different sizes

in the UK and the US?

We're going to weigh out 100 grams of chocolate M&M's

and count them to see how many you get.

One, two, three ...

Two, three, four, five ...

[fast-forwarding]

That is so annoying!

It was so close to being 100 grams

of exactly 100 M&M's,

but instead 100 grams of UK chocolate M&M's

is 102 M&M's.

100 grams of American M&M's

is 114 M&M's.

So what does that mean, ours are smaller?

And how do we feel about that?

I don't know if it's better or worse.

But portion size don't stop there.

You can also buy M&M's directly from the M&M website.

The main purpose of this seems to be

catering for large events like weddings or parties.

You can technically get smaller-than-average portion sizes,

but only in bulk quantities.

For example, in the US, you can get these.

Tiny party-favor packs of M&M's

weighing just 0.75 ounces each.

Or they have party-favor tins,

which contain 1.5 ounces of M&M's.

But both of these have to have a minimum

of 20 or more units.

Now, what doesn't require a minimum order,

however, are the bulk bags.

In the US you can order bulk bags

of 1 pound, 2 pounds, or 5 pounds.

Now, technically, you could order 10 pounds of M&M's,

but they just send you two 5-pound bags,

which is a bit disappointing, so we just got one.

5-pounder.

Look at these M&M's.

The UK website is a similar situation.

Our smallest portion size is this 28-gram designer case.

But the minimum order for these is 20.

Unlike the US, we only have one bulk-bag order.

And that's this one, which is 1.5 kilograms.

That's around 3.3 pounds, which is a 34% decrease

from the largest single bag size in the US.

If you do order M&M's on the website,

you can customize them.

We chose some custom colors

and also put some custom text on the M&M's.

In terms of colors, I went for this

lovely blue-and-white color scheme

to match my stunning M&M's T-shirt.

Then I had some fun putting some text options on there.

Firstly, I went for "Harry

We also had to rep the show,

so I put a "Food Wars" one on there.

Then, because I have the mind of a child,

I tried to put some swear words on the M&M's,

and it turns out they actually try and censor you.

For example, if you try and put the word "poop" on an M&M,

a warning message will flash up

telling you to get in touch with the team.

But there is a work-around.

For example, for the word "poop,"

by replacing the O's with 0s,

I was able to get around the censorship

and create poop M&M's.

The same goes for replacing the I with a 1 in "penis"

and replacing the A with a 4 in "balls."

This is some serious journalism taking place right here.

Now, Harry, of course, went with customizing M&M's

with fun words and stuff on it.

I just went for pictures.

You can get custom images on an M&M.

So what I did is I got

Harry face and Joe face M&M's.

OK, that'll show 'em.

Here are all the ingredients in chocolate M&M's in the UK.

And here is everything in a bag

of classic M&M's in the US.

Look at all those colors.

A few things to note here.

Firstly, the food colorings used

in the two countries are wildly different.

In the UK, some of our colors are natural,

including the curcumin and the carotenes.

Whereas in the US, all our colors are artificial.

Blue No. 1 is used in both the US and the UK,

but we also have Blue No. 2, Red 40,

Yellow 5, and Yellow 6.

Blue 2 is a less common one.

It's also known as indigo carmine.

Now, the good news is it won't make your kids hyperactive.

The more interesting news is that Blue 2

is filtered rapidly through the kidneys,

and consuming enough of it will turn your pee blue.

The practical use of this is so doctors

can highlight your urinary tract for surgeries.

A less practical effect or use is to freak out your friends.

Hey-o, we're doing jokes in the script, apparently.

Hey, welcome to "Food Wars"!

So anyway, turns your piss blue.

Speaking of carmine,

what about the carmine used in British M&M's?

Standard carmine is a red food coloring

with the code names Red 4 or E120.

It's a natural food dye,

but what is the natural source, you ask?

It's cochineal beetles.

If you grind up cochineal beetles,

you're left with a red powder,

which when mixed with water and some chemicals

can be turned into a very stable dye.

Obviously, we're going to now have to try and make our own.

But you can see the red color coming off of it already.

Now I'm going to try and put some of this in there,

mix it with some water, and see what happens.

That has really worked. Wow.

Look how red that is! That's incredible.

As you can see, just by chopping up some beetles

and mixing it with water, we've got this incredible

kind of blood-red food dye.

Now, while apparently synthetic alternatives

to carmine do exist, M&M's confirmed to us

that the carmine they use does in fact come from beetles.

So, technically, every time you eat a red M&M in the UK,

you're eating bugs.

So, do you want your kids hyperactive,

or do you want them eating beetles?

Not much of a choice, is it?

Here are all the M&M's products you'll find in the UK

that you won't find in the US.

These are the M&M products you'll find in the US

that you will not find in the UK.

I'm so excited for this, Yuelei. You have no idea.

Oh, my God, I'm want to try every single one of these.

And I'm going to right now.

All right, first up, peanut butter M&M's.

Love peanut butter M&M's.

Fudge brownie.

They're like the size of peanut M&M's,

but it's all chocolate inside.

I'm having a hard time deciding the difference

between the fudge brownie and regular chocolate.

Pretzel M&M's are my favorite M&M's.

These might be the best ones.

Every time M&M comes out with a new core,

it's always like, oh, who cares?

Pretzels, peanut butter, crispy.

And they're always amazing!

Mm.

Caramel M&M's.

Mm.

A more manageable Rolo. These are great.

Almond. He's a new guy.

These are really good.

Dark chocolate M&M's.

Not a big dark chocolate guy.

A little more bitter than the regular ones,

but they're still coated in candy.

Coffee nut. Oh, they're big.

Oh, and they're kind of, like,

the many shades of coffee-colored.

Oh, I don't know about these.

The only good coffee-flavored thing is coffee.

Everything else is like, don't bother.

First miss.

Mint dark chocolate.

Smells a little bit like toothpaste.

Ooh. It's like, yeah, it's got a nice refreshing ...

this could replace brushing your teeth in the morning.

Eat a couple of these.

White chocolate peanuts.

Yeah, dude, yeah.

Like the peanut ones but a little bit sweeter.

And, surprised this one is not in the UK.

It is English toffee peanut.

No.

One variety, mega peanut,

is also available here in the US and not in the UK,

but at the time of filming this,

I was not able to get my hands on it.

From what I understand,

it's like the peanut's really big.

Now, we don't have any major exclusive flavors in the UK,

but we do have some linguistic differences.

For example, while the US has caramel,

we have salted caramel.

And while the US has fudge brownie,

we have chocolate brownie.

I want to see if you can actually taste the salt

in the salted caramel.

You actually can.

Now, I am a sucker for salted caramel,

but these are really good.

We also have a bunch of seasonal M&M's in the US.

These include Christmas options,

such as sugar cookie M&M.

What is up?

Oh, yeah.

Those are good.

Mint Christmas.

Do M&M's go bad? Christmas was, like, two months ago.

Yeah. Ooh, yeah.

Bro. White chocolate pretzel snowballs.

I think we had these for the Christmas episode. I forget.

White chocolate.

The pretzel gives it that little bit of salt.

These are really good.

We also have Valentine's Day options.

This is a Cupid mix,
