Heat cooking oil in the deep fryer to 375°F.

Slice onions into desired thickness then toss with ¼ cup cornstarch or flour. This helps batter stick to the onions better.

Mix together all dry ingredients, mix in ice water until a pancake consistency is reached.

Dip a few onion rings in batter and drop carefully into hot oil one at a time.

Remove when golden brown, and drain on paper towel.

Sprinkle with salt if needed.
