Cast-Iron Duck Breast Tacos with Yuzu-Charred Salsa & Hatcho Miso Beans

Instructions

1. 1

   Thoroughly dry 2 whole (about 8oz each) Duck breasts (boneless, skin-on) with paper towels. Score the skin in a tight crosshatch pattern, spacing cuts about 1/4-inch apart. Season both sides with 1 tsp Kosher salt and 0.5 tsp Sansho pepper (or black pepper).

   5 min

   Tip: Why this works: Scoring the skin gives the melting fat an escape route, ensuring shatteringly crisp skin instead of a rubbery chew.

2. 2

   Place the seasoned duck breasts skin-side down in a cold, dry cast-iron skillet. Turn the heat to medium-low and let the fat render out slowly. Do not touch them for about 15 minutes, until the skin is deeply golden and crispy.

   15 min

   Tip: Starting in a cold pan is the golden rule of duck cookery. If you drop it into a hot pan, the skin seals immediately, trapping the fat inside.

3. 3

   While the duck renders, husk and rinse 4 medium Tomatillos, halve 1 whole Jalapeño, and trim 4 stalks Negi (Japanese long onion) or large scallions.

   5 min

   Tip: Keep the veggies nearby; they are going to get aggressively charred in the duck fat.

4. 4

   In a small saucepan over medium heat, combine the mostly drained 1 15oz can Canned black beans, 2 cloves Garlic, and 1.5 tbsp Hatcho miso. Cook, mashing with a fork until it forms a thick, rustic puree. Keep warm.

   10 min

   Tip: Hatcho miso is made entirely from soybeans, giving it an earthy, almost chocolatey depth that mirrors the flavor of black beans. It's a cross-cultural umami bridge.

5. 5

   Remove the duck breasts to a plate, leaving them skin-side up. Pour off the rendered liquid gold (duck fat) into a heatproof jar, leaving about 1 tablespoon in the skillet.

   2 min

   Tip: Save that jarred duck fat! Use it to roast potatoes tomorrow.

6. 6

   Crank the heat under the cast-iron skillet to screaming high. Once the residual duck fat starts to smoke, drop in the tomatillos, jalapeño, and negi. Let them blister aggressively, turning occasionally, until heavily charred and softened.

   10 min

   Tip: We want the pan looking like a Tokyo yakitori grill—don't be afraid of the black, blistered spots. That's pure flavor.

7. 7

   Transfer the charred vegetables to a blender or food processor. Add 2 tbsp Yuzu juice, 1 tbsp White soy sauce (Shiro shoyu), and the remaining 0.5 tsp Kosher salt. Pulse until chunky but combined. Pour into a bowl.

   5 min

   Tip: The yuzu cuts through the smokiness of the char and the richness of the duck fat beautifully.

8. 8

   Return the cast-iron skillet to medium-high heat. Place the duck breasts back in, flesh-side down this time. Sear hard to build a crust, about 2-3 minutes for medium-rare.

   3 min

   Tip: Watch the temperature with a meat thermometer if you're nervous; pull it at 130°F.

9. 9

   Remove the duck to a cutting board and let it rest undisturbed.

   10 min

   Tip: If you cut it now, the juices will run everywhere and ruin your crispy skin. Patience!

10. 10

    Wipe out any burnt bits from the skillet, lower heat to medium, and brush the pan with a little of the reserved duck fat. Toast 8 whole Corn tortillas until pliable and slightly blistered on the edges.

    5 min

    Tip: Duck fat tortillas. You're welcome.

11. 11

    Slice the duck breasts thinly. To assemble, smear a spoonful of the warm miso black beans onto a tortilla, lay down a few slices of duck, spoon over the yuzu-charred salsa, and garnish with 8 leaves Fresh shiso leaves (torn) and 2 whole Radishes (sliced).

    5 min

    Tip: Tear the shiso leaves right before serving so their volatile oils hit your nose right as you take a bite.
