Fish Tacos al Pastor

Preparation

1. Step 1

   Bring guajillo and morita chiles and 1½ cups water to a boil in a medium saucepan. Cover, remove from heat, and let sit 30 minutes to let chiles soften.

   Step 2

   Place fish in a large bowl or baking dish. Transfer chile mixture and soaking liquid to a blender. Add orange juice, achiote paste, 4 garlic cloves, ¼ cup lime juice, and 1 Tbsp. salt and purée until smooth, about 2 minutes. Reserve 1 cup chile sauce for serving; leave uncovered at room temperature. Pour remaining purée over fish; toss to coat. Cover and chill 1–3 hours.

   Step 3

   Meanwhile, mix onion, habanero chile, pineapple, 3 Tbsp. cilantro, and remaining garlic clove, 3 Tbsp. lime juice, and 1½ tsp. salt in a medium bowl. Cover and chill until ready to use.

   Step 4

   Prepare a grill for medium-high heat; thoroughly clean grates and brush with oil. Working in batches if necessary, grill fish, leaving a few inches of space between each piece, until marinade is dried and begins to caramelize and char, 2–3 minutes. Using a fish spatula, release fish from grates, turn, and continue to grill until charred on second side and flesh flakes easily with a fork, 2–3 minutes more. Transfer to a cutting board and let rest 10 minutes.

   Step 5

   Grill tortillas until just beginning to char, about 30 seconds per side. Top each tortilla with a piece of fish, a light schmear of reserved chile purée, and a spoonful of pineapple salsa. Top with cilantro. Serve with lime wedges for squeezing over.

   Step 6

   Do Ahead: Pineapple salsa can be made 4 hours ahead. Keep chilled.
