Grilled Herb Shrimp - The Barefoot Contessa

3 garlic cloves, minced
1 medium yellow onion, small-diced
1/4 cup minced fresh parsley
1/4 cup minced fresh basil
1 teaspoon dry mustard
2 teaspoons Dijon mustard
2 teaspoons kosher salt
1/4 teaspoon freshly ground black pepper
1/4 cup good olive oil
Juice of 1 lemon
2 pounds jumbo shrimp (16 to 20 per pound), peeled (tails left on) and deveined

Mango Salsa (recipe follows)

Combine the garlic, onion, parsley, basil, mustards, salt, pepper, olive oil, and lemon juice. Add the shrimp and allow them to marinate for 1 hour at room temperature or cover and refrigerate for up to 2 days.

Prepare a charcoal grill with hot coals, brush the grilling rack with oil to prevent the shrimp from sticking. Skewer the shrimp. (I soaked the skewers in cold water for a few hours.) Ina used 5 to 6 shrimp on a 12-inch skewer for a dinner serving. Grill the shrimp for 1 1/2 minutes on each side. Serve with the Mango Salsa. This can also be done on a gas grill.
