Defrost the strawberries, pour over with vinegar, stir thoroughly and put aside for ca. 30 minutes to pickle. Mash bananas in a bowl, then pour into the flour with the baking powder, soda, salt and sugar. Stir everything (but not too much) so that all ingredients merge well. Afterwards lay off 12 muffin cups on baking form, put into the cups the prepared dough (top of the cupcakes sprinkle with sugar) and put in the up to 180°C preheated oven.
