2 pickled jalapeños, plus 2 tbsp of the juice
1/4 cup to 1/2 cup fresh lime juice
1/2 cup soy sauce
1/2 cup vegetable oil
5 peeled garlic cloves
1 tsp cracked black pepper
1 fistful of fresh cilantro leaves
Combine and blend all ingredients, except fish, in blender until smooth. Marinate fish for 30.40 minutes. Grill over medium hot coals until cooked through. Baste with the reserved marinade several times during cooking. Serve with lime wedges, avocado slices and pico de gallo.
You can also use this marinade on boneless, skinless chicken breast, for a couple hours through, and then barbacue like the fish.
