Just a few from the large batch this recipe provided.
Pour your peanut oil into a cast iron pot. (A larger pot will suffice, but cast iron fries so well. You can also use a deep fryer.) Heat the oil.
Thickly slice one large or two smaller onions.
Blend together in a bowl 1 1/4 cups flour, 1 teaspoon salt, 1 teaspoon baking powder.
Add onion rings and toss to coat.
Remove onion rings, shaking excess flour mixture off and place the rings on a plate.
Add 1 cup milk and 1 beaten egg to the flour mixture and blend well.
On another plate or shallow bowl, prepare your coating. I used organic yellow corn meal and grated old biscuits with some salt to flavor. You can use Panko bread crumbs, regular bread crumbs, cracker crumbs. You can add your own seasonings (I don't recommend this if you plan on reusing your oil. You can add a seasoned salt to your rings once cooked).
Dip the onion rings into the flour batter. It'll stick well and you may want to let some of it slide off. Then dip and coat in the coating and place in the hot oil.
