When oil is hot, using your fingers fish out several rings and drop into oil. Only add enough rings to form a single layer on the oil. Fry until underside is beginning to brown, 2-3 minutes. Flip rings over and continue to cook for an additional 2-3 minutes until golden. Remove from oil using a slotted spatula or spoon and allow to drain on a paper towel lined plate. Repeat with remaining rings and serve immediately with cumin dip.
