Onion Rings - One of my favorite sides!
Mix all of the dry ingredients (not the onion) together in a bowl. Pour the buttermilk into a separate bowl.
Pour the frying oil into a pan and heat to 350 degrees.
Slice the onion into rings.
Dip each ring into the flour mixture and set aside on a tray. Once they are all floured, dip them each into the buttermilk, then flour then buttermilk then flour again to double coat them.
Gently place a few onion rings at a time into the hot oil and fry for about 2 minutes or until golden brown and crispy. Place the cooked rings onto a rack to cool and sprinkle with some salt. Repeat until all rings are cooked.
