These are really easy and fun and great with chilli dipping sauce, or use Sauce Chien. Don’t be put off by the deep-frying; it is easy to do at the last minute if you take alittle care.
Pull the heads off the prawns and remove the little legs. (You can either discard these trimmings or use them to make fish stock.) With a sharp knife, make a shallow cut down the back of each prawn and, with your finger or a cocktail stick, remove and discard the black vein. If the prawns are very large, cut them in half.
