Spicy red chile sauce, made with New Mexico red chile powder, is used as both a marinade and a dipping sauce for these small brochettes, which are ideal party food. They are best grilled outdoors over coals, but also work fine on a stovetop cast iron grill or under the broiler. Threading each piece of meat onto two skewers, rather than one, keeps the meat from twirling and makes it easier to grill. (If you’re using bamboo skewers, soak them in warm water for 15 minutes, so they won’t catch fire.)
04In a blender or food processor, put 1/2 teaspoon salt, 2 tablespoons chile powder, the charred tomato, the garlic, the lime juice, the olive oil and 1 teaspoon cumin. Blend to obtain a smooth sauce and transfer to a bowl.
05Lay brochettes on a tray in 1 layer. Spoon 8 tablespoons chile sauce over pork and spread to cover evenly. (Save remaining sauce.) Leave at room temperature for 1 hour, or refrigerate several hours, then bring to room temperature.
06Grill over medium-hot fire for about 3 minutes per side. Sprinkle with remaining toasted cumin. Serve with reserved sauce.
