The traditional toppings for the Alsatian Flammkuchen are cultured cream, thinly sliced onions, and fatty bacon cubes. Other toppings also work well.

Making the dough

1. In a mixing bowl, combine the flour, salt, and olive oil. Stir in the water bit by bit. Once all the water is incorporated, knead the dough using the palm of your hands for about 5 minutes until smooth. Cover the dough with plastic wrap and let it rest in the fridge for at least 15 minutes.
2. Preheat your oven to 250°C.
3. Roll the dough out as thinly as possible. It should literally be just a little thicker than paper. The traditional shape would be a rectangle with curved edges but you can roll it out into any shape you'd like.
4. Add the toppings and bake the flammkuchen in the middle tray of the oven for 10-12 minutes until the crust is super crispy and the top is lightly charred.
