Rinse the chicken pieces well and pat dry with paper towels. Prick the skin all over with tines of a fork. In a small bowl, combine the coriander, black pepper and salt and rub into the chicken pieces. Set aside. Soak the tamarind pulf in the boiling stock off the heat for 15 minutes. Stir and mash it with a fork to help it dissolve. Strain through a fine strainer into a bowl, pressing on the solids with the back of a wooden spoon to extract all the liquid. Set aside. Stem the chiles and shake out the seeds. Using scissors, cut the chiles into pieces. Soak in warm water to cover for 10 minutes. Drain well. Combine the chiles, garlic, shallots, ginger, lemongrass, tamarind liquid, oil, soy sauce, sugar, ketchup, and basil in a food processor and process to a puree. Arrange the chicken in a large shallow dish and pour the marinade over. Cover and refrigerate 2 hours or overnight. Preheat the broiler. Remove the chicken pieces from the marinade and arrange in a baking dish deep enough to later accommodate the marinade. Broil the chicken until browned and half cooked, about 10 minutes. Pour the marinade over the chicken, turn the pieces on the other side, and broil until cooked through, another 10-15 minutes. If the chicken is browning too quickly, move the baking dish further away from the broiling element. If your oven and broiler are controlled by the same dial, reduce the temperature from broil to 375F. Remove the chicken pieces to a serving dish and pour the pan juices over it. Serve at once. Serves 4-6. NOTES : Risas notes: * I didnt have canned broth or fresh so I used 1/3 tsp Better Than Bouillon Chicken Base and 1/3 cup water and boiled it together. Worked just fine. ** I didnt have any so I omitted this from the recipe. *** I didnt have any basil so I used another herb (I had parsley, mint and cilantro so I used one of them). After broiling for the first 10 minutes, I took off the skin from the thighs and poured the marinade over it. I found it easier than removing it when fresh. Then I continued the broiling until finished. Recipe by: Terrific Pacific by Anya Von Bremzen Posted to CHILE-HEADS DIGEST by RST G on Apr 20, 1999,
