Using a large mixing bowl, mix all ingredients until no lumps remain. Use jumbo yellow onion rings and slice about 3/4-inch thick.
Coat the onion rings evenly in batter and deep fry at 350 degrees F in vegetable oil just until batter sticks to the rings. Remove the rings from the vegetable oil and drain well, then refrigerate the rings for 2 to 4 hours. You can keep refrigerated for 1 to 2 days loosely covered.
When ready to serve, drop the onion rings into 350 degrees F vegetable oil until golden brown.
