　　The citrusy dressing makes this dish a standout, and there's plenty extra to be sopped up with rice or crusty bread. Cooking shrimp in their shells keeps them juicy and tender. It all makes for casual finger food that requires plenty of napkins — which is part of the fun.

　　

Ingredients

Makes 6 servings

　　3 lb jumbo shrimp in shell (7 or 8 per pound)

　　4 large garlic cloves

　　3/4 teaspoon salt

　　5 tablespoons fresh lemon juice

　　1/2 teaspoon black pepper

　　3/4 cup olive oil

　　1/4 cup finely chopped fresh oregano (from 1 bunch)

　　3 lemons, each cut into 6 wedges

　　

Step 1

Snip through shells of shrimp along middle of back using kitchen shears, exposing vein and leaving tail and adjoining segment of shell intact. Devein shrimp, leaving shells in place.

　　

Step 2

Mince and mash garlic to a paste with salt using a large heavy knife or a mortar and pestle. Transfer to a blender along with lemon juice and pepper and blend until smooth. With motor running, add oil in a slow stream, blending until emulsified. Transfer dressing to a bowl and stir in chopped oregano.

　　

Step 3

Prepare grill for cooking over direct heat with medium-hot charcoal (moderate heat for gas).

　　

Step 4

Toss shrimp with 1/4 cup dressing in a large bowl and marinate no more than 15 minutes. (Texture of shrimp will change if marinated too long.)

　　

Step 5

Lightly brush lemon wedges with some of remaining dressing and grill, turning over once, until grill marks appear, 3 to 5 minutes. Transfer to a large platter.

　　

Step 6

Grill shrimp on lightly oiled grill rack (covered only if using a gas grill), turning over once, until just cooked through, 7 to 8 minutes total. Transfer to platter with lemons as grilled. Serve with remaining dressing.

　　Cooks' note:

　　If you aren't able to grill outdoors, preheat a lightly oiled well-seasoned large (2-burner) cast-iron grill pan over moderate heat until hot but not smoking, then cook lemon wedges and shrimp (in batches if necessary) in same manner as above.
