Makes about 4 round tarte flambée when rolled out thinly.
Make a pre-dough from yeast, water and sugar. Let rise for about 15 minutes until a clear layer of foam has formed.
Put the flour in a bowl and make a well in the middle. Pour the pre-dough into the well and knead everything into a smooth dough. The dough then needs a warm place to rise for about 45 minutes. But be careful that it doesn`t get too warm. Yeast dies from 45 ° C.
Roll out thinly, spread about half a cup of sour cream thinly per serving and top it as you like.
In the oven preheated to maximum heat of approx. 250 ° C top / bottom heat, ideally bake on a pizza stone for approx. 10 minutes until the dough is nice and crispy.
