Re: Onion Rings Recipe

3 large red onions or any other sweet onions
1/2 cup flour
3/4 teaspoon salt
1/8 teaspoon pepper
1/2 teaspoon baking powder
1 egg, well beaten
1/2 cup milk
cooking oil for deep frying

Wash and peel onions, cut into 1/4-inch thick rounds.
Separate rounds into rings.
In a bowl, combine flour, seasonings, and baking powder.
In a measuring cup, whisk together egg and milk.
Add milk mixture to dry ingredients, blending well.
Dip onion rings into batter, then put into hot oil.
Fry until golden brown, turning to brown both sides.
Remove to paper towels to drain thoroughly.
Sprinkle with a little salt before serving.
