In a large skillet, heat 2 tablespoons of the garlicky oil from the mojo until shimmering. Add half of the shrimp and a generous pinch each of salt and pepper and cook over moderately high heat, turning once, until golden and just cooked through, about 3 minutes. Transfer the shrimp to a platter. Repeat with 2 more tablespoons of the garlicky oil and the remaining shrimp. Top the shrimp with more garlic mojo and garnish with chopped cilantro. Serve with lime wedges, passing the remaining garlic mojo at the table.
