Step 1

Soak onions in buttermilk for at least 10 minutes.

Step 2

In a shallow dish add flour, salt, and pepper and mix well.

Step 3

In a large pan heat vegetable oil to 375 degrees.  To test to see if your oil is ready for frying, dip the handle of a wooden spoon in the oil and if it bubbles around the handle then it's ready.

Step 4

Dredge buttermilk soaked onions in flour until well coated and add to oil, frying in batches until golden brown then remove form oil with a slotted spoon and drain on a paper towel lined plate.  Continue with all of the onions with additional paper towel lined plates after a double layer of onions are on one.

Step 5

Use immediately or store in an airtight container in a dry cool place for up to a few days.
