Leave about ⅓ dough for decoration. The rest of the dough roll out the layer in the form for baking and distribute it on the bottom and sides. Mix the cherry with the starch and sugar and place on the dough.
Roll out the remaining dough in a thin layer, cut into strips and make a braid on the cake. Lubricate the batter with a beaten egg. Bake the cake at 200 ° C for about 25-30 minutes until it browns.
