I had one of these things last saturday. It was astoundingly tasty.
You just blew this thing wide open!
I'm not from the USA, so let me take you on my voyage of discovery.
Where I'm from a grill is a hot element, usually built in to your oven, that cooks things from above with radiant heat.
Cheese on toast, cooked under a grill is common here. So when I heard people talking about grilled cheese I imagined it was similar.
But then I saw it and realised no, this isn't mere cheese on toast. There are two layers of bread, a whole sandwich.
This hot cheesy concoction is what I would call a toastie. I wouldn't ideally use the grill, but it works well enough.
Mystery solved, until I found out that what I call a grill is known as a broiler in most of the USA.
And it's not a broiled cheese, so how is it cooked?
I asked a friend, what do they call a grill?
They explained it's a hot flamey contraption with a wire rack over it that you use outside.
Aha, a barbecue I thought!
But surely you wouldn't barbecue a sandwich.
So, I ask, how do you cook a grilled cheese?
It's fried, they reply.
>chicken fried steak
No he fucking didn't
That's a montecristo
