I tried making Sufganiot (a kind of jelly doughnut) this Hanukkah, and ran into a problem. I've let the dough rise, made balls, then let them rise again. However, all balls split along the seam lines (where I've rolled a piece of dough that wasn't originally ball-shaped into a ball), resulting in doughnuts that were very far from round.
What did I do wrong, and how can I prevent this from happening in the future?
