Serves 4 as a side
1-2 large onions, peeled and thickly sliced
1/2 cup all-purpose flour
flour for dredging onion rings
Add enough oil to a large deep pot to come up to 1 1/2 inches deep, but at least 4 inches below the top of the pot. Heat oil to 375f. To make batter, whisk flour, cornstarch, baking powder and salt together. Whisk in soda water and egg. Coat onion rings in flour, shake any excess off and dip into batter. Deep fry about 1-2 minutes or until golden and crispy. Drain on paper towels, sprinkle with sea salt and serve immediately.
