Crisp Onion Rings

These are best eaten as soon as they are made, but you can also make them ahead and reheat at 400°F for 3 minutes.
Ingredients :

• 1-1/2 cups buttermilk
• 1/4 tsp. cayenne (or more, to taste)
• 2 sweet onions, thinly sliced
• 1 cup all-purpose flour
• salt and pepper, to taste
• vegetable oil, for frying

Cooking Procedures :

1. In a bowl, combine buttermilk, cayenne and onions.  Let sit for 15 minutes.
2. On a plate, combine flour, salt and pepper.
3. Remove onions from buttermilk with tongs.  Toss onions in flour until lightly coated.
4. Heat about 2 inches oil in a wok or skillet to 350°F, or until a cube of bread turns brown in 15 seconds.  Fry rings, in batches, for about 2 minutes, or until golden.  Drain on paper towels.
