Spicy Grilled Shrimp with Feta Dipping Sauce

Preheat a gas or charcoal grill to high (450°F to 500°F). Place minced garlic on a cutting board; sprinkle with salt. Using the flat side of a knife, mash the salt into the garlic to make a paste. Transfer the garlic paste to a large bowl; stir in 2 tablespoons oil, lemon zest, 3 teaspoons lemon juice, paprika, oregano, cayenne and 1/4 teaspoon pepper. Fold in shrimp until fully coated. Let stand for 5 minutes.

Meanwhile, combine yogurt, feta, water and the remaining 1 tablespoon oil, 2 teaspoons lemon juice and 1/4 teaspoon pepper in a medium bowl.

Thread the shrimp evenly onto 8 (6-inch) skewers. Oil the grill rack by holding an oil-soaked paper towel with tongs (do not use cooking spray on a hot grill). Place the skewers on the oiled rack; grill, uncovered, until opaque and lightly charred, 2 to 3 minutes per side. Serve with the dipping sauce.
