Rocoto & Pisco Braised Pork Belly "Kakuni" with Ginger-Sweet Potato Purée

Rocoto & Pisco Braised Pork Belly "Kakuni" with Ginger-Sweet Potato Purée

Japanese kakuni meets Peruvian chicharrón con camote. We are taking fatty chunks of pork belly and slow-braising them until they wobble, using floral Pisco and fiery rocoto paste instead of the usual sake. Resting on a silky, ginger-spiked sweet potato purée, this is meltingly tender, deeply savory Nikkei comfort food that will ruin you for standard braises.

Ingredients

  • 2 lbs Pork belly(Skinless, cut into 1.5-inch cubes)
  • 1 tbsp Neutral oil(Canola or grapeseed)
  • 1/2 cup Pisco(Peruvian brandy; can sub dry sake if unavailable)
  • 2 cups Dashi(Awase dashi (kombu and bonito))
  • 1/2 cup Soy sauce(High quality Japanese soy sauce)
  • 1/4 cup Mirin
  • 3 tbsp Dark brown sugar
  • 2 tbsp Rocoto paste(Peruvian red chili paste, adjust based on heat preference)
  • 4 cloves Garlic(Smashed)
  • 1 inch Ginger (sliced)(For the braise)
  • 2 medium Sweet potatoes(Orange-fleshed (camote), about 1.5 lbs total)
  • 1/4 cup Whole milk(Warmed slightly)
  • 2 tbsp Unsalted butter(Room temperature)
  • 1 tsp Ginger (grated)(For the purée)
  • 2 stalks Scallions(Green parts only, finely sliced for garnish)
  • pinch salt(Mentioned in Step 5 for boiling sweet potatoes.)

Instructions

  1. 1

    Heat 1 tbsp neutral oil in a heavy-bottomed Dutch oven over medium-high heat. Add the 2 lbs pork belly cubes and sear deeply on all sides until a crispy golden-brown crust forms. This Maillard reaction is your base layer of flavor.

    8 min

    Tip: Don't overcrowd the pan; sear in batches if necessary so the meat actually browns instead of steaming.

  2. 2

    Carefully pour in the 1/2 cup Pisco to deglaze the pan, scraping up all those beautiful browned bits from the bottom. Let the alcohol cook off for about 2 minutes, then stir in the 2 cups Dashi, 1/2 cup soy sauce, 1/4 cup mirin, 3 tbsp dark brown sugar, 2 tbsp rocoto paste, 4 cloves garlic, and 1 inch ginger (sliced).

    5 min

    Tip: Stand back when adding the Pisco if cooking over a gas flame, as it can occasionally ignite.

  3. 3

    Bring the liquid to a very gentle simmer. Cover the pot with a tight-fitting lid, lower the heat to its lowest setting, and let it braise peacefully for 90 minutes. The liquid should barely bubble—this gentle heat ensures the collagen melts into gelatin without the meat seizing up.

    90 min

    Tip: You can also do this in a 300°F oven if your stovetop runs too hot.

  4. 4

    While the pork braises, prepare the sweet potatoes. Peel and chop the 2 medium sweet potatoes into uniform 1-inch chunks so they cook evenly.

    10 min

  5. 5

    Place the chopped sweet potatoes into a medium pot, cover with cold water, and add a generous pinch of salt. Bring to a boil over medium-high heat and cook until completely tender when pierced with a fork.

    20 min

  6. 6

    Drain the sweet potatoes and return them to the warm pot. Mash them vigorously with the 1/4 cup whole milk, 2 tbsp unsalted butter, and 1 tsp ginger (grated) until silky smooth. Cover to keep warm.

    5 min

    Tip: For a restaurant-quality texture, push the purée through a fine mesh sieve.

  7. 7

    Carefully remove the tender pork belly from the braising liquid and set aside. Turn the heat under the Dutch oven to medium-high and boil the remaining liquid for 10 minutes until it reduces to a thick, glossy syrup.

    10 min

    Tip: Keep an eye on it at the very end; the sugar content means it can go from a glaze to burnt quite quickly.

  8. 8

    Return the pork belly to the reduced glaze, tossing gently to coat each piece in the sticky sauce. Spoon the warm ginger sweet potato purée onto plates, top with the glazed pork belly, and garnish with the finely sliced 2 stalks scallions.

    5 min

Chef's Notes

Here's why this works: The alcohol in Pisco acts as a brilliant solvent for both water-soluble and fat-soluble flavor compounds in the rocoto and pork. Slow braising around 200°F breaks down the tough collagen in the belly into rich, lip-smacking gelatin without squeezing the muscle fibers dry. And the sweet potato? It perfectly balances the salty, spicy umami bomb of the braising liquid. Don't rush the reduction at the end; that sticky glaze is the best part.
