This is something I made on Father's Day that was really good. It's a variation of a tequila-lime marinade I've been using for awhile. This one's simpler and even better IMO. If you like these flavors, this is worth trying. Next time I might add some chopped cilantro to the marinade (that's for you, mar52!
Tequila-Lime Grilled Shrimp
2 pounds large shrimp (preferably in the shell; I used the frozen/shelled/deveined shrimp from TJ's which worked fine)
1/4 cup fresh lime juice
1/4 cup tequila
2 medium garlic cloves, minced
1 large shallot, finely chopped
2 tsp. cumin (or to taste; I only used about 1 1/4 tsp.)
1/2 tsp. kosher salt (or more, to taste)
1/4 tsp. fresh ground pepper
1/3 cup olive oil
Whisk together lime juice, tequila, garlic, shallot, cumin, salt and pepper. Slowly whisk in olive oil until well combined. Taste for seasoning.
Pour over shrimp in nonreactive container or Ziploc bag. Marinate in fridge for 1 to 4 hours (I did it for about 3 which was perfect).
Prepare grill for medium-heat. Skewer the shrimp...if using wood skewers, let them soak in water first for at least 30 minutes. Grill shrimp about 3 inches from the fire, turning once until cooked through, about 3-4 minutes per side. Garnish with lime slices.
