Crispy Onion Rings with Raising Cane's Sauce

In a bowl, combine mayonnaise, ketchup, Worcestershire sauce, garlic powder, black pepper, and paprika. Mix until smooth and glossy.

Slice a large onion into ½-inch rings. Soak the rings in ice-cold water for 10 minutes, then drain and pat completely dry.

In a bowl, mix flour, cornflour, paprika, garlic powder, salt, pepper, and baking powder. Slowly add cold water until you get a thick, glue-like batter.

In another bowl, mix together the panko breadcrumbs and dried parsley for the crispy coating.

Dip each onion ring into the batter, let the excess drip off, and then coat generously in the panko mixture, pressing lightly.

Heat neutral oil to 350-360°F (175-180°C). Fry the onion rings in batches for 2-3 minutes per side until deep golden and crispy. Drain on a wire rack before serving.
