I'm not talking about ingredient differences like adding blueberries or chocolate chips, or even buttermilk or cooked pumpkin to the batter ...
How many fundamentally different regional types of 'pancake' are there? Either stuff called a 'pancake' or 'pan cake' in English, or where the literal translation to English is 'pan cake', even if it's qualified in some way (eg, a 'potato pancake')
(I'm not interested solely in wheat batter based pancakes ... I'm actually interested in finding items that are the furthest away from American pancakes, but that some group would still call a 'pancake')
update : oddly enough, this is indirectly a followup to my question on overpressurizing whipped cream. It was for a contest at my place of work called "Your Science as Food", and well, I won, so I'm trying to come up with a follow-up for next year. I've done the heliophysics theme for the last two years, by "my science" is actually information science, so I was thinking about having an exhibit with lots of 'pancake' items, and having a little survey of 'is it a pancake?' similar to this But Is It a Sandwich? survey, and want to find things that people will have to think about for a while if it's a 'pancake' or not.
