Instructions
- 1
Score the skin of 2 duck breast in a tight crosshatch pattern without cutting into the meat. Rub both sides with 3 tbsp shio koji. Set aside at room temperature to cure while preparing other components.
20 min
Tip: Shio koji enzymes work fast! 20 minutes is plenty of time to break down surface proteins and create intense savory flavor.
- 2
In a small saucepan, bring 1 cup forbidden black rice, 1.75 cups water, and 0.5 tsp kosher salt to a boil over high heat. Reduce heat to low, cover tightly, and simmer until water is absorbed.
25 min
Tip: Don't lift the lid while simmering; trapped steam ensures even cooking of dark whole grains.
- 3
In a small bowl, mix 0.5 cup fresh kumquats, 2 tbsp rice vinegar, 1 tbsp mirin, and 0.25 tsp kosher salt. Let pickle at room temperature to draw out sweet juices. Stir in 4 fresh shiso leaves (chiffonade cut) right before serving.
5 min
Tip: Kumquat peels are sweet while the flesh is tart, creating an instant balanced quick pickle.
- 4
Heat a dry skillet over medium heat and toast 0.5 cup raw pepitas until puffed and fragrant, about 3 minutes; transfer to a bowl. In the same skillet with 1 tbsp olive oil, char 1 medium poblano pepper, 1 medium serrano pepper, 3 small tomatillos, and 2 cloves garlic until blistered with dark spots.
10 min
Tip: A deep char on the peppers gives the mole its complex smoky depth.
- 5
Transfer charred vegetables to a blender. Add half of the toasted pepitas (reserve 2 tbsp toasted pepitas for garnish), 1 tbsp white miso paste, 0.5 cup chicken stock, 0.5 cup fresh cilantro leaves, 4 fresh shiso leaves, and 1 tbsp lime juice. Puree until smooth.
5 min
Tip: Miso replaces traditional Mexican chocolate/sweetness here with rich umami depth.
- 6
Wipe excess shio koji off 2 duck breast with a paper towel. Place skin-side down in a cold cast-iron skillet. Turn heat to medium-low and slowly render fat for 10-12 minutes until skin is golden and crisp. Flip and cook meat side for 3-4 minutes until internal temperature reaches 130°F (54°C).
15 min
Tip: Starting in a cold pan allows duck fat to render out gently without scorching the rice-koji sugars.
- 7
Transfer duck to a warm plate and rest for 5 minutes before slicing against the grain. Remove black rice from heat, fluff with a fork, and stir in 1 tsp toasted sesame oil.
5 min
Tip: Resting allows muscle fibers to relax so juices reabsorb into the duck.
- 8
Divide black rice between two wide shallow bowls. Pour a warm pool of Mole Verde Miso beside the rice. Fan sliced duck breast over top. Garnish with pickled kumquat-shio relish, 1 medium radish, and reserved 2 tbsp toasted pepitas.
5 min
Tip: Serve immediately while the duck skin is at its crunchiest.
Chef's Notes
Why this works: Shio koji contains active enzymes—specifically proteases and amylases—that break down duck muscle proteins into free amino acids (glutamate = pure umami) while converting starches into simple sugars. During the slow, cold-pan render, these sugars caramelize into an insanely crispy crust while keeping the meat juicy. Pairing this rich duck with a toasted pumpkin seed and white miso Mole Verde builds a seamless bridge between Oaxacan and Japanese flavor traditions, while the quick-pickled kumquat and herbal shiso provide the bright acid required to cut through every rich bite.
