Onion Strings

1 large onion (I used a Vidalia)
2 cups buttermilk (I added 2 Tbsp white vinegar to 2 cups of milk)
2 cups flour
1 scant tablespoon salt
Lots of black pepper
1/4 to 1/2 teaspoon Cayenne Pepper (I used 1/2 tsp.)
Canola Oil

Slice onion very thin. If you can see through it, it's thin enough.. Break the slices into rings and place in a baking dish and cover with buttermilk for at least one hour.

Combine dry ingredients and set aside in a separate bowl.

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. Separate as they fry, fry for a few minutes and remove as soon as they are golden brown.  Drain on paper towels.   Stay there by stove, they cook very fast. Repeat until onions are gone.
