I believe my family would eat onion rings until I dropped from exhaustion from frying them. If you like thin sliced, extra crunchy onion rings, this is the recipe for you.
3 large yellow onions, thinly sliced
3 cups buttermilk
1 - 2 T. of your favorite hot sauce
2 cups self rising flour
Mix buttermilk and hot sauce together in a large bowl. Place onion slices in buttermilk to soak for at least 30 minutes.
Heat peanut oil in deep fryer to 375 degrees.
Using a fork, remove onion rings from buttermilk and dredge (a half dozen or so at a time) in flour and shake off excess.
Fry in hot oil until well browned. Drain on paper towels and lightly salt. Devour immediately.
