For the dough: butter, flour and sugar - beat with a blender or mixer into crumbs, add water, knead the dough, roll into a ball, wrap in foil, put in the refrigerator for at least 30 minutes.
Roll out the dough into a circle with a thickness of 5 mm, you can immediately put it on baking paper, sprinkle starch on top (through a sieve).
Cut the strawberries into quarters. Spread out the strawberries, stepping back from the edge by about 2 cm. Sprinkle with two tablespoons of sugar.
Wrap the edges of the dough inside. Brush the top of the sponge cake with water and sprinkle with the remaining sugar (1 tbsp. l.)
Bake in a preheated 180 degree oven for 30-45 minutes until golden brown. Enjoy your meal!
I have a slightly cracked dough around the edges, because I rolled it out too thin, but it didn't hurt to try it - delicious!
