In a restaurant, you can't order just one. They came in stacks - if you only want a couple, it's called a "short stack". Here is a short stack of American pancakes, before and after embellishment, as seen and later devoured at the Southern Belle Truckstop.
I'm not sure that America cherishes the concept of Shrove Tuesday as "pancake day", as Britain does. Every day is pancake day in America. The restaurant chain IHOP, which, I only recently realised, stands for "International House of Pancakes" did hold a pancake day this year but I think they got their wires a little crossed. It was on February 5th. Hence I've had to educate hubby, who is an American-style pancake chef par excellence. And as I write, I can hear him, quite unprompted, getting the griddle out.
