Applebee's Onion Straws

1 large sweet onion
2 cups buttermilk
2 cups all purpose flour
1 tablespoon of salt
freshly ground pepper
1/4 teaspoon cayenne pepper
canola oil, for frying

Slice onion very thin. Place in a baking dish and cover with buttermilk for at least one hour.
Combine dry ingredients and set aside. Heat oil to 375 degrees.

Grab a handful of onions, throw into the flour mixture, tap to shake off excess, and plunge into hot oil. Fry for a few minutes and remove as soon as golden brown. Repeat until onions are gone.
