Homemade tempura beer onion rings

I also made tempura beer onion rings. They were so yummy. I made a lot so I had to freeze the rest. I will make them again, later on. Can't have to much of these. 

2 medium onions. Peeled, sliced them 1/2 inch thick, seperated them into rings.

1/2 cup flour
1/2 cup tapioca flour
1/4 cup cornstarch
1 teaspoon salt
1/2 teaspoon cayenne pepper
1 teaspoon garlic salt
1 teaspoon white pepper
1 teaspoon baking soda
1 teaspoon baking powder

In a large container add all ingredients, mix with a fork

1 bottle Munkholm alkohol free beer

Poured beer slowly little at a time, mixed into the flour mixture. (the whole bottle) Whisk well (batter will be a little lumpy).

Added onion rings into tempura batter, coverd with lid, shake container until onion rings were covered well. Set a side for half hour. I heated vegetable oil in a deep large pot on medium/high heat (filled oil half way). Fried them for about a minute until golden crisp. Layed crispy onion rings on a rack to get rid of excess oil. Served with homemade dipping sauce.
