This is a fundamental step and requires skill and training. Picaroneras do this effortlessly, but with a little practice, you can get similar results. Have a bowl with cold water nearby; with one wet hand, take a portion of dough and before dunking in the hot oil, with your thumb try to make a ring. Then, with a long wooden stick, turn the Picarones. This goes on, all the time. These require a portion of Picarones at a time.
