Ingredients
  

  • 2 large onions
  • 2 cups buttermilk
  • 2 cups all-purpose flour
  • ½ scant Tablespoon salt
  • ½ Tablespoon Season Salt
  • Black pepper to taste
  • ¼ teaspoon cayenne pepper optional
  • Canola oil or vegetable oil for frying

Instructions
 

  • Peel onions and slice very thin. Separate the onion slices and place them in a large shallow bowl. Pour buttermilk over the top. Press onion slices down so they're submerged as much as possible. Soak at room temperature for at least an hour. Stir them around half way through the soaking process.
  • In a large bowl, combine flour, salt, seasoning salt, black pepper, and cayenne. You can also add a hefty pinch of garlic and onion powder if desired.
  • Pour 1 to quarts of oil in a large dutch oven or pot. Heat to 375°F, or until a pinch of flour sizzles when sprinkled over the pot.
  • Using tongs, remove a handful of onions from the buttermilk. Immediately dunk into the flour mixture. Coat the onions in the flour mixture, and tap to remove any excess flour.
  • Carefully release the onions in the hot oil. With a spoon, fiddle with them a bit just to break them up. Watch them! They cook quickly and will be ready to remove in no time.
  • When they are golden brown, remove from the oil and place on a paper towel-lined plate.
  • Repeat with remaining onion slices and serve immediately while hot.
