Tuna Carnitas

On a menu full of fresh Mexican seafood dishes, deep-fried tuna stands out. At Este in Austin, TX—one of our Best New Restaurants of 2023—chef Fermín Nuñez transforms the delicate fish into crispy-but-tender cubes reminiscent of their porky namesake, piled atop a swoosh of creamy, smoky refried beans. While some diners were initially wary of tuna transformed this way, it won over many hearts (including that of our own restaurant editor Elazar Sontag) with its perfect balance of rich and bright flavors.
Nuñez uses fatty tuna belly at the restaurant, but this recipe recreates the dish’s hallmark texture with tuna steak tossed in rice flour before frying. And while the most time-intensive part of the recipe is braising dried pinto beans, don’t worry; you’ll be rewarded for your patience with enough leftovers to stow in the freezer for a rainy day.

Preparation
Step 1
Toast 3 morita chiles, stems removed, in a medium Dutch oven over medium heat, turning occasionally, until fragrant, about 2 minutes. Add 1 medium tomato, halved, 1 medium yellow onion, halved, 10 garlic cloves, smashed, 1 lb. dried pinto beans, and 1 avocado leaf (if using); pour in water to cover by at least 2". Increase heat to high and bring to a boil. Reduce heat and simmer gently, adding water as needed to keep beans submerged, 1½ hours.
Step 2
Add 1 Tbsp. Diamond Crystal or 1¾ tsp. Morton kosher salt and continue to cook until beans are tender, 45–60 minutes. Remove avocado leaf; discard. Drain beans through a mesh sieve set over a medium bowl; set bean cooking liquid aside. Return beans and solids to pot.
Step 3
Meanwhile, cook 8 oz. bacon, coarsely chopped, in a large cast-iron skillet over medium heat, stirring occasionally, until browned and very crisp, about 20 minutes. Transfer bacon to a small bowl with a slotted spoon, leaving fat behind. Set skillet with fat aside.
Step 4
Place 1 medium red onion, thinly sliced, in a small heatproof bowl. Bring 1 Tbsp. sugar, 1 cup distilled white vinegar, 2 tsp. Diamond Crystal or 1 tsp. Morton kosher salt, and ½ cup water to a simmer in a small saucepan over medium, then pour over red onion and set aside to pickle.
Step 5
Add bacon, 1 tsp. dried oregano, 1 tsp. garlic powder, 1 tsp. ground coriander, 1 tsp. smoked paprika, 2 cups reserved bean cooking liquid, and remaining 3 Tbsp. distilled white vinegar to pot with bean mixture. Using an immersion blender, blend until smooth. Season bean mixture with more salt if needed. (Alternatively, you can blend in batches in a regular blender.)
Step 6
Pour 1 cup vegetable oil into another medium Dutch oven or heavy pot (it should come about ½" up sides); fit with thermometer and heat over medium-high. Add bean mixture and cook, stirring and scraping bottom and sides of pot with a heatproof rubber spatula, until homogeneous and emulsified, about 3 minutes. Remove from heat; cover with plastic wrap, pressing directly onto surface (this will prevent a skin from forming).
Step 7
Season 1 lb. tuna steaks, patted dry, cut into 1" pieces, with salt, then place in a medium bowl. Add ¼ cup (45 g) rice flour or cornstarch; toss to coat. Pour fresh oil into reserved skillet with fat to come 1" up sides. Fit with thermometer and heat until thermometer registers about 400°. Working in batches, cook tuna, tossing constantly, until lightly crisped on the outside but still a little pink in the center, about 30 seconds per batch. Transfer to a wire rack set inside a rimmed baking sheet; season with salt.
Step 8
Scoop beans onto plates and smooth into an even layer; top with tuna, drained pickled onion, and microgreens or cilantro. Serve with warmed tortillas and lime wedges.
