Spicy Mango Fish Tacos

Why This Spicy Mango Fish Tacos Works

In the oven, the fish cooks quickly and stays moist because it is coated in olive oil and spices. The oil covers the surface, so the heat doesn’t dry it out as much, and the spices form a light crust. As the fish heats up, the flesh firms and then starts to flake apart in big, soft pieces that sit nicely in the tortillas instead of falling into mush.

While the fish bakes, the mango, jalapeño, onion, and cilantro sit together with lime juice and a little salt. Over a few minutes, the salt and acid pull some juice out of the mango and onion, so the salsa becomes a bit more saucy and less chunky-dry. That juicy salsa soaks slightly into the warm tortillas and the shredded cabbage, so every bite isn’t dry. At the end, cool sour cream and sharp lime zest sit on top of the hot fish, so each taco has soft, flaky fish, crisp cabbage, and juicy mango all holding together in one bite.

Mistakes To Avoid

Letting the fish bake too long dries it out and makes it tough and stringy instead of flaky. Once it passes the “flakes easily” point, the moisture cooks off and the fillets shrink and harden, so the tacos end up chewy and unpleasant instead of soft and tender.

Using underripe mangoes for the salsa leaves the cubes hard and starchy, so they don’t break down or release much juice. The salsa then feels dry and chunky, and the tacos lose the fresh, juicy contrast that balances the spicy fish.

Cutting the jalapeño too big or not removing the seeds and ribs can throw off the heat. Large, seed-filled pieces create random pockets of intense burn in some bites while other bites stay mild, so the tacos feel uneven and harsh instead of gently spicy.

Skipping the step of warming the corn tortillas often leads to cracking and breaking as soon as the fish and salsa go in. Cold tortillas stay stiff and brittle, so the fillings fall out and the tacos are hard to pick up and eat.
