Remove the thin membrane found at the underside of the ribs. Cut into one-rib sections (individual ribs) and place in a large bowl.
Combine the spices (salt, garlic powder, onion powder, ground black pepper and baking soda) in a small bowl and sprinkle over the ribs. Mix very well to coat the meat (to distribute the baking soda evenly), cover and let sit for 30 mins to an hour.
Combine the flour and cornstarch/rice flour in another bowl. Mix and dredge each rib until fully covered. Set aside.
Heat a deep frying pan and add about one inch of oil (or just enough to cover the ribs. When hot enough, add a few, making sure to not crowd the pan.
Fry for about 12 minutes (flipping halfway) or until golden brown. Fry in batches as crowding the pan will result in steam build up and fried ribs will come out oily.
