Instructions

Blend your rehydrated guajillo chiles with the achiote paste, orange juice, and lime juice until completely smooth.
Combine this mixture with half of the diced pineapple to create the base for your Roasted Fish al Pastor recipe.
Marinate your fish fillets in this mixture for thirty minutes to allow the flavors to penetrate the surface.
Preheat your oven to 400 degrees Fahrenheit to ensure an even cook for your Roasted Fish al Pastor recipe.
Place the fillets on a parchment-lined baking sheet to prevent sticking during the cooking process.
Roast the fish for 12 to 15 minutes, or until the edges begin to develop a slight char.
Add the remaining pineapple on top during the last three minutes of the Roasted Fish al Pastor recipe cooking time.

Pat the fish fillets dry with a paper towel before applying the marinade to help the sauce adhere better to the surface.
