Make more for a party.
Great to make on camping trip; in a deep Dutch oven over open fire.
Watch the oil does not catch fire.Just like Red Robin's onion straws.
Soak in cold water; set aside. Heat oil in deep skillet or fryer or Dutch oven to 375^to 400^.
Drain onions. Toss into flour mixture, shake off excess, then in buttermilk, then back in flour mixture- shaking off excess flour.
Repeat until all are fried.
