Beer Battered Onion Rings

For the lime mayo sauce:
In small bowl, combine mayo, ketchup, black pepper, ground cayenne pepper, garlic and lime juice. Set aside.

For the onion rings:
Set 1/4 cup of flour aside on a shallow plate. In medium bowl, combine remaining 1 cup flour, ground cayenne pepper, cumin, black pepper, garlic powder, beaten egg and 1 cup to 1 1/2 cups beer depending on how thick you want the batter.

Heat oil to 375ºF.

Dip onion rings in reserved flour on shallow plate and then into batter. Fry battered onion rings in the hot oil until browned, about 4 minutes. Place on paper towels while working in small batches.

Serve hot with lime mayo sauce.
