Ingredients
- 4 dried guajillo chiles, stemmed and seeded
- 1 dried chipotle chile, stemmed and seeded
- 1 pound Roma tomatoes, about 4 to 6 tomatoes
- 3 cloves garlic, smashed and peeled
- 2 scallions
- 1 teaspoon dried Mexican oregano
- 1/2 teaspoon ground allspice
- 1/2 teaspoon ground cumin
- 1 teaspoon fresh thyme
- 2 tablespoons apple cider vinegar
- 2 tablespoons unsalted butter
- 1 ounce Mexican chocolate, such as Ibarra, chopped (about 3 tablespoons)
- 1 teaspoon sea salt
- 2 pounds jumbo head-on shrimp (U9 to U14), shell on, deveined
- 1 tablespoon olive oil
- Lime wedges, to serve (optional)
Directions
- Heat a dry skillet over medium heat. Add the guajillo and chipotle chiles to the skillet and toast until fragrant and slightly brighter in color, 1 to 2 minutes per side.
- In a medium saucepan, combine the toasted chiles, whole tomatoes, and garlic cloves. Cover three-quarters of the way with water and bring to a boil over medium-high heat. Reduce the heat to medium and simmer until the tomatoes are very soft and their skins start to break, 8 to 10 minutes. Use a slotted spoon to transfer the solids to a blender. Chop the whites of the scallions and add to the blender. Thinly slice the scallion greens and reserve for garnish. Add the oregano, allspice, cumin, thyme, vinegar, butter, chocolate, and salt. Blend on high until completely smooth. Pour the sauce into a large bowl and let cool slightly.
- In a medium bowl, toss the shrimp with 1 cup of the prepared sauce. Allow the shrimp to marinate for 1 hour in the refrigerator.
- Meanwhile, have ready metal skewers or wooden skewers soaked in water for at least 30 minutes. Heat a small saucepan over medium heat. Add the olive oil to the pan and heat another 30 seconds. Add the reserved sauce to the saucepan and cook over medium-low heat, stirring often, until reduced and thickened slightly, 4 to 5 minutes. Keep warm.
- Prepare a grill or grill pan over medium-high heat. Skewer each shrimp starting between the head and the body and pushing the skewer through the tail to straighten the shrimp. Grill the shrimp over medium-high heat until the shells are charred in spots and bright pink and the meat is cooked through, 3 to 4 minutes per side.
- Brush the grilled shrimp with some of the reduced sauce. Loosen the shrimp slightly from the skewers to make them easier for the guests to eat. Serve them sprinkled with the scallion greens and with lime wedges (if using) and the reduced sauce alongside for dipping.
