10 long red chiles (such as Holland or Anaheim), stemmed
8 garlic cloves
2 1' pieces ginger, peeled
1/4 cup fresh lime juice
2 tablespoons palm sugar or (packed) light brown sugar
Instructions:
Combine shrimp, 2 Tbsp. fish sauce, 2 Tbsp. oil, and turmeric in a large bowl; toss to coat. Let stand for 30 minutes.
Purée 4 Tbsp. fish sauce, 2 Tbsp. oil, cilantro, and remaining ingredients in a blender or food processor until a coarse mixture forms; transfer dipping sauce to a small bowl and set aside.
Build a medium-hot fire in a charcoal grill, or heat a gas grill to high. Oil grill grates. Shake excess liquid from shrimp and place shrimp on grill. Cook, turning occasionally, until shrimp are charred and cooked through, 5-6 minutes. Serve immediately with sauce.
