Combine the cornflour, cayenne pepper and garlic granules in a bowl along with a generous pinch of seasoning. Heat the oil in a high-sided frying pan over a medium-high heat. Coat the sea bass in the cornflour mix, patting to make sure it sticks well to both sides, then carefully lay in the pan and fry for 2-3 mins on each side, carefully flipping over once, until golden and cooked through.
