How to make Grilled Prawns with Tamarind Sauce
Prepare grill for cooking.
Soak prawns (still in shells) in salt water 5 minutes, then rinse well in a colander.
Place tamarind in a bowl with water and rub with your fingers to dissolve pulp. Pour through a sieve into a bowl, pressing hard on solids, and discard solids.
Heat oil in a small heavy saucepan over moderate heat until hot but not smoking, then cook coriander paste and garlic, stirring, until fragrant. Stir in hot sauce, 3 tablespoons tamarind juice, palm sugar, and fish sauce. Simmer until thickened to consistency of light syrup, about 3 minutes.
Snip shells of prawns with scissors down centre of back, from wide end to second-to-last tail section. Butterfly prawns in their shells, making a deep incision along length of back where shells are cut, and devein.
Grill prawns on their sides on an oiled rack set 5 to 6 inches over glowing coals until shells are pink and slightly charred and prawns are just cooked through, 3 to 4 minutes on each side. (Alternatively, grill prawns in a hot well-seasoned ridged grill pan over moderate heat.)
Spoon tamarind sauce over prawns (still in shells) in a serving dish.
