1 cup well-stirred canned unsweetened coconut milk
1 tablespoon soy sauce
1 1/2 teaspoons curry powder

2 teaspoons cornstarch
1 whole skinless boneless chicken breast (about 3/4 pound)

Spicy Szechuan Triple Nut Butter Dipping Sauce, recipe follows

In a small bowl stir together coconut milk, soy sauce, curry powder, and ground coriander until combined well. Stir in cornstarch, mixing thoroughly. Cut chicken lengthwise into 10 (1/2-inch-thick) strips and add to cornstarch mixture, stirring to coat. Marinate chicken, covered and chilled, at least 1 hour and up to 24 hours, refrigerated.

Prepare grill. Thread 1 piece chicken onto each skewer and grill on an oiled rack set 5 to 6 inches over glowing coals until cooked through, about 3 minutes on each side. Serve with Spicy Sichuan Peanut Sauce.
