1/4 cup chopped cilantro
2 tablespoons Asian fish sauce
1 1/2 teaspoons freshly ground pepper
4 whole chicken legs, skinned
1/2 teaspoon tamarind concentrate (see Note) dissolved in 1 teaspoon water
1/4 cup Asian fish sauce
2 tablespoons fresh lime juice
1 small garlic clove, minced
1 small Thai chile, seeded and minced
2 teaspoons sugar
1 tablespoon water
1/2 tablespoon vegetable oil
1/2 cup chopped cilantro
MARINATE THE CHICKEN In a mini food processor, process the cilantro, fish sauce and pepper to a coarse puree. Coat the chicken with the marinade. Let stand at room temperature for 20 minutes.
PREPARE THE DIPPING SAUCE In a bowl, combine the dissolved tamarind with the fish sauce, lime, garlic, chile, sugar and water.
Preheat the oven to 400°. Light a grill. Rub the chicken with the oil and rub the grill with an oiled paper towel. Grill the chicken over moderately high heat, turning, until charred, 12 minutes. Transfer the chicken to a baking sheet and roast for 30 minutes, until cooked.
Just before serving, stir the cilantro into the dipping sauce and serve with the chicken.
