A whole, of course. Sweet, definitely. So, what kind of doughnuts do you like?

Chocolate, glazed, powdered, filled with jelly, or custard?

Maybe a dig strawberry frosted like Homer Simpson?

Different variations of these fried treats are enjoyed all around the world,

but there's one continent people seem to enjoy them the most. Any guesses?

If you said North America, you're right! More than 10 billion doughnuts are made in the USA each year!

While Canada has the most doughnut shops per person, there are dozens and dozens of doughnut types,

and that doesn't even take into consideration toppings. Shout out some of your favorite toppings.

I heard sprinkles, cookie crumbs, breakfast cereal, bacon, oh, bacon.

No matter which you prefer, we've certainly come a long way from the donut-like treats of ancient

Rome and Greece, which were coated in something called fish sauce. So, what were early doughnuts like?

Were they even round? And why are they even called doughnuts? It's time for a whiff of double glazed

science on...

Ahoi smarty pants! Welcome to the deep sea! This is where your donut story continues!

Don't worry, we're not here to talk about fish sauce!
