Tokyo Meets Mexico City: Crispy Chashu Carnitas Tacos
I remember sitting on a plastic stool in Oaxaca at 2 AM, eating carnitas that tasted like pure magic, and thinking, "What if I braised this like Japanese chashu?" That late-night, fat-fueled epiphany led to these Crispy Chashu Carnitas Tacos.
We're taking pork belly and slow-braising it in a soy, sake, and ancho chile broth. Here is why this works: the amino acids in the soy sauce act as a natural tenderizer, breaking down the tough connective tissue until the collagen yields like warm butter. But the real secret is the finish. We hit it with a viciously hot sear right before serving. This triggers the Maillard reaction on overdrive, crystallizing the soy-ancho sugars into a jagged, sticky crust.
To balance that umami bomb, I serve it with a Yuzu Kosho Guacamole. The fermented citrus-chile paste cuts through the rich pork fat with incredible precision.
Want to make it your own? Swap the ancho for a smoky pasilla, or toss in a spoonful of fermented garlic honey if you have a jar bubbling on your counter (and you really should!). Don't overthink the plating—just grab a warm tortilla and let the fat drip down your chin.

What happens when a Tokyo izakaya and a Mexico City taqueria fall in love? You get these Chashu Carnitas. I'm taking pork belly and slow-braising it in a soy-sake-ancho broth until the collagen yields like butter, then finishing it with a viciously hot sear to crystallize the sugars into a jagged, crispy crust.

Timeline
Ingredients
- 2 lbs Skinless pork belly(Cut into 2-inch blocks)
- 1/2 cup Soy sauce(High quality Japanese soy sauce)
- 1/2 cup Sake(Drinking quality, not cooking sake)
- 1/4 cup Mirin
- 1 cup Water
- 1 whole Orange(Juiced, peels reserved)
- 4 cloves Garlic cloves(Smashed)
- 1 inch Fresh ginger(Sliced)
- 1 whole Dried ancho chile(Stemmed)
- 1 tsp Mexican oregano
- 1 piece Kombu(About 2x2 inches)
- 2 whole Avocados(Ripe)
- 1 tbsp Yuzu kosho(Green yuzu kosho preferred)
- 1 whole Lime(Juiced)
- 1/4 cup White onion(Finely diced)
- 1/4 cup Cilantro(Chopped, plus extra for garnish)
- 4 whole Red radishes(Thinly sliced)
- 8 whole Corn tortillas
Instructions
- 1
In a heavy Dutch oven, combine 1/2 cup soy sauce, 1/2 cup sake, 1/4 cup mirin, 1 cup water, the juice and peels of 1 whole orange, 4 smashed garlic cloves, 1 inch sliced fresh ginger, 1 stemmed dried ancho chile, 1 tsp Mexican oregano, and 1 piece kombu.
5 min
Tip: This liquid is the backbone of our mashup. We're bridging the savory, oceanic depth of Japanese chashu with the aromatic citrus and spice of traditional Mexican carnitas.
- 2
Nestle 2 lbs skinless pork belly into the liquid. Bring to a boil over medium-high heat, then reduce to the lowest simmer, cover tightly, and let it go for 90 minutes. We want the meat jiggly but not entirely disintegrating.
90 min
Tip: Food science moment: Slow braising around 160°F-180°F breaks down the tough collagen network into luscious gelatin. If it boils too hard, the muscle fibers will seize and become stringy. Low and slow is the law.
- 3
While the pork braises, let's build our guacamole. In a bowl, roughly mash 2 ripe avocados. Fold in 1 tbsp yuzu kosho, the juice of 1 whole lime, 1/4 cup finely diced white onion, and 1/4 cup chopped cilantro.
10 min
Tip: Yuzu kosho is essentially a Japanese fermented citrus-chili paste. It cuts through the rich fat of both the avocado and the pork belly perfectly.
- 4
Thinly slice 4 whole red radishes and set aside with some extra cilantro for garnishing. Now go check on your sourdough starter or have a beer while the pork finishes its magic.
5 min
Tip: Keep the radishes in ice water if you want them extra crisp.
- 5
Check the pork—a skewer should meet zero resistance. Carefully remove the pork belly blocks to a wire rack or cutting board. Let them rest for 15 minutes.
15 min
Tip: Crucial step! Cooling slightly firms up the newly formed gelatin. If you try to sear them right out of the boiling liquid, they'll turn to mush in your pan.
- 6
Strain the braising liquid, discarding the solids. Return the liquid to the pot and boil vigorously until reduced to a syrupy glaze. This should take about 10-15 minutes.
15 min
Tip: Watch the bubbles—when they start stacking on top of each other and look glassy, the glaze is ready.
- 7
Heat a dry cast-iron skillet over high heat until just smoking. Add the rested pork belly blocks. Sear hard for 1-2 minutes per side until deeply browned and crusty.
5 min
Tip: This is where the magic happens. The residual sugars from the mirin and orange will caramelize instantly, and the surface fat renders out, creating a jagged, crispy carnitas-style crust via the Maillard reaction.
- 8
Warm 8 whole corn tortillas in a dry skillet. Smear each with the yuzu kosho guacamole, top with a piece of crispy chashu carnitas, drizzle generously with the reduced glaze, and garnish with the sliced radishes and extra cilantro.
5 min
Tip: Assemble and eat immediately. Tacos wait for no one.
Chef's Notes
I'm a massive nerd for textural contrast. Boiled meat is texturally boring on its own, but when you combine the gelatinous, tender interior of a slow braise with the shattered-glass crunch of a hard cast-iron sear? It's culinary alchemy. Don't skip the resting period before you sear, or your beautiful pork belly will disintegrate.

Where Japanese precision meets global flavors
I trained in Tokyo for eight years, mastering the discipline of washoku—traditional Japanese cuisine. But I got restless. So I cooked my way through Southeast Asia, spent a year in Mexico City, and fell hard for the food of Peru. Now I see connections between cuisines that others miss: the umami in dashi and fish sauce, the heat in shishito and Szechuan peppercorns, the way Japanese technique can unlock flavors from any tradition. I'm always fermenting something.
