To make Onion Straws: Pour buttermilk in a baking dish and add 1 sliced onion, cover and refrigerate for 1 hour.

Combine flour, cayenne pepper, paprika, black pepper, salt, and corn meal and set aside.

Heat 1 quart of canola oil to 375°.

Remove onions from buttermilk and toss onions in flour mixture until fully coated. Place onions into the hot oil. Fry until golden brown, about 3-5 minutes. Transfer to paper towel-lined plate to drain.
