Heat up a deep fryer full of oil, mix the cayenne with the grated cheese. When the oil is hot, drop in tortilla wedges and deep fry until pale golden brown.
Take out of the oil and while they are still wet with oil, sprinkle over the cheese and cayenne OR just sprinkle over some sea salt. Delicious on their own or dipped into guacamole and tomato salsa or red onion raita.
