Add a third of the rings to the batter, and then carefully move the rings one at a time to the heated oil. BE careful not to crowd the rings, as they won’t cook properly. Allow to fry for about 5 minutes, flipping once, until golden brown. Remove with a slotted spoon and allow to drain on a baking sheet with a paper towel. Remove any floating bits of batter, and continue to fry in small batches.
