Lightly sprinkle the cup with flour, put the dough into it, cover with a towel. This is a towel, you can not cover the dough with a lid and, moreover, tighten it with a film!!! The dough should breathe. We put our dough in a warm place (I put it to the battery) for 12 hours. You can bake a little earlier, a little later. The main thing is that the dough does not fit more than 24 hours.
