Heat oil in skillet or deep fryer to 350 - 375 degrees
In a medium bowl mix flour and spices. Pour in the sparkling water or beer until a batter forms. You want it the consistency of a thick pancake batter.
Slice your onion into rings. Typically between 1/2 - 1 inch thick dependign on preference. Seperate the individual rings.
Dip each ring into the batter, shaking off any excess. Then drop the ring into the hot oil.
Allow each ring to fry for 2 -3 minutes or until golden brown. You can fry several rings at once, just try not to over crowd your pan.
Once the rings are cooked use a fork or tongs to remove from the hot oil and place on a paper towel lined plate to rest.
Lightly salt while warm and serve with dipping sauce
