Chicken Satay with Peanut Dipping Sauce from Martha Stewart

4 skinless boneless chicken breast halves or 1 pork tenderloin (about 1 pound)
1 teaspoon coarse salt
1/4 teaspoon ground turmeric
1/4 teaspoon ground coriander
1/8 teaspoon cayenne pepper
1 3/4 cups (14-ounce can) light unsweetened coconut milk
Vegetable oil cooking spray
Directions
If using chicken, cut each piece lengthwise into 1/2-inch-wide strips; you should get about 5 strips per half. Place strips between two sheets of plastic wrap, and pound lightly to an even thickness of about 1/4 inch. If using pork, cut crosswise into 1/4-inch-thick slices. You should get about 24 slices; set aside.
In a 9-by-13-inch baking dish, combine salt, turmeric, coriander, and cayenne pepper; whisk to combine. Whisk in coconut milk. Add meat, turning to coat. Cover with plastic wrap, and let marinate, refrigerated, for at least 2 hours and up to overnight.
Soak skewers in hot water to cover for 30 minutes. Preheat grill pan over medium-high heat.
Meanwhile, remove marinated meat from refrigerator, and thread onto skewers, letting excess marinade drip off. Spray grill pan with cooking spray. Working in batches, grill until cooked through, 1 to 3 minutes per side. Transfer to a serving platter. Serve hot with sauce.
Peanut Sauce
1 tablespoons peanut oil
1 small onion, finely chopped (about 1/2 cup)
2 garlic cloves, minced
1 to 2 teaspoons chile paste
1/2 teaspoon curry powder
1/4 cup smooth peanut butter
1/4 cup unsweetened coconut milk
2 tablespoons packed dark-brown sugar
2 teaspoons unseasoned rice vinegar
2 teaspoons coarse salt
1/4 cup coarsely chopped roasted unsalted peanuts
Directions
In a medium skillet, heat oil over medium heat. Add onion and garlic, and cook until translucent, 3 to 5 minutes. Transfer to a blender. To the same skillet, add the chile paste and curry powder. Cook, stirring until fragrant, about 1 minute. Add to blender. Add the peanut butter, coconut milk, sugar, vinegar, salt, 2 tablespoons warm water, and 2 tablespoons of peanuts. Blend until smooth.
Transfer to a bowl, and let stand until room temperature. Before serving sprinkle with remaining peanuts. The sauce may be made 1 day ahead and refrigerated in an airtight container (press plastic wrap directly on top of the sauce to prevent a skin from forming.) Let sauce return room temperature for 1 hour before serving.
