Break the egg into a bowl, then whisk in the iced water. Add the flour and mix roughly with a chopstick to create a lumpy mixture with pockets of flour. Take a prawn by its tail, dust in flour, dip in the batter, then drop into the oil. Repeat with the remaining prawns: fry in 2 batches for 3 minutes each, until golden. Drain on kitchen paper and serve with the sauce.
