Much like “stuff wrapped into a dough tube and fried,” most cultures have “stuff scattered on top of some dough and cooked.” In Germany, this is Flammkuchen. It’s uses dough about as thin as a tortilla, but sturdier. Common toppings are cream, arugula and (shockingly) ham. It’s usually circular, but I’ve gotten in shaped in a square as well. We’ve seen it sold at farmer’s markets and from other street vendors, sometimes alongside some regional wine. You probably don’t want to confuse it with Pfannkuchen, which is like a dessert pancake.
It makes for a filling lunch as long as you aren’t really hungry. We had some particularly good Flammkuchen this past weekend at A2 am See.
