Your spicy onion ring recipe looks fantastic! Have never seen this mix of ingredients and can't wait to try. We have not had much luck making the "blossom" at home, but have the instructions, if you're interested. Instead, we end up making a "loaf," which will work great with your recipe.
Cut onion into really, really thin circles. Coat each one and press all into a deep fry basket-in one big bunch. Fry for about 15 minutes at 385 degrees so the middle rings are also done and turn out on a plate to drain. If it turns out right, they're all crispy and stringy.
