Tequila Marinated Spareribs

1 rack pork spareribs (about 3 pounds)
Salt
Freshly-ground black pepper
1 cup olive oil
Juice from 4 limes
1/2 cup gold tequila
1 onion, finely chopped
2 tablespoons minced garlic
2 medium jalape?os, stemmed, seeded, and finely chopped
2 tablespoons finely chopped fresh cilantro leaves

Season the ribs with salt and pepper. In a small mixing bowl, whisk the oil, lime juice, tequila, onions, garlic, jalapenos, and cilantro. Season with more salt and pepper. Place the ribs, meat side down, in a glass baking dish. Pour the marinade over the ribs, coating each side completely. Cover with plastic wrap and refrigerate overnight (at least 12 hours), turning every couple of hours.

Remove from the refrigerator and bring the ribs to room temperature.

Preheat the grill on low. Place the ribs, meat side down, and grill them, turning and basting every 15 minutes. Cook for about 1 1/2 to 2 hours, or until the ribs are tender. Remove from the grill and slice into individual ribs.
