In a large mixing bowl, mix tempura flour, salt, white pepper, and flavor seasoning. Gradually add ice-cold water to make a batter.
Heat oil in a wok or deep-frying pan. Dip a prawn into the batter, then into the breadcrumbs, making sure it's well-coated. Fry the prawn in hot oil until it's golden. Cooking time varies by prawn size. Make sure not to overcook, or prawns will shrink. Serve immediately with a dipping sauce.
