1. Working with one ball at a time, drop into batter and submerge to coat, then remove with a fork and lower into the pot of oil. After a few minutes, gently nudge off the bottom of the pot so it doesn’t burn; it should float to the top of the oil. Fry until evenly browned on all sides, and remove to paper-towel-lined pan to drain. Repeat with remaining balls.
2. Sprinkle balls with confectioners’ sugar and serve hot, along with the sauce of your choice.
3. If preparing in advance, refrigerate or freeze balls once fried. Bring to room temperature before heating through.
