- 1-quart vegetable oil (for frying)
- 2 Walla Walla sweet onions, sliced into rings
- 1 cup milk
- 3 tablespoons vegetable oil
- 1 1/4 cup flour
- 1/4 cup cornstarch
- 1 tablespoon baking powder
- 1 teaspoon sugar
- 1 egg
Preheat vegetable oil for frying in a small deep fryer to 365-375°F. If you’d rather, you can heat it in a heavy duty pan and use a thermometer.
- Place milk, 3 T. oil, flour, cornstarch, baking powder, salt, sugar, and egg in a medium-sized bowl. Whisk well. The mixture should be thick but nice & smooth. Allow tempura mixture to sit while oil finishes heating up.When frying oil reaches at least 365°F, coat a ring of onion with tempura mixture and carefully place in fryer. Repeat with a few more pieces. Do not crowd fryer because if you do, it will cool down your oil too much. Consequently, oil that has cooled down too much will make for soggy breading rather than a lovely crunchy coating.
Cook onion rings for about 4 minutes. Use a utensil that’s safe in hot oil to move onion rings around a bit during the cooking process so they are cooked on all sides. The coating should be a beautiful golden brown.
Finally, place onion rings on a baking tray covered with a few paper towels. Sprinkle with sea salt. Serve hot.
