Heat oil in deep-fat fryer or heavy large frying pan. For frying pan, oil should be about one third up the side of pan and heated to 350 degrees. KEEP AN EYE ON THE OIL! If using deep-fat fryer, follow directions for amount to use and temp of oil.
Mix all ingredients except oil. Set aside and peel onion and slice into rings..not too thick. Dip into batter, let drip a little, and slide into oil. BE CAREFUL, IT MAY SPLATTER A BIT! When onions come to top and are golden brown, remove, salt and drain on paper towel.
This makes enough rings (depending on the size of the onion) for two side dish servings. But, then we like onion rings! For more, gotta use more onions! Enjoy alone or (our favorite!) with steak or fried catfish.
