Turn the roll with the edges glued down.
Do the same for the rest of the rolls and the other dough balls.
Calculate the number of rolls depending on the size of the cake you want to make:
- my cake is based on 7 pieces - I needed a total of 28 rolls - it's a big cake, be careful
- for one with a base of 6 pieces - you will need 21
- at the base with 5 rolls - 15
