Baja-Nikkei Halibut Ceviche with Yuzu Kosho Leche de Tigre

Baja-Nikkei Halibut Ceviche with Yuzu Kosho Leche de Tigre

Where the coastal crudos of Ensenada meet the precision of a Tokyo sushi counter. We're using green yuzu kosho—a fermented Japanese paste of citrus, chili, and salt—to build a complex, fiery, and deeply umami curing liquid for fresh halibut.

Ingredients

  • 1 lb Fresh halibut(Skinless, pin-bones removed. Sushi-grade if possible.)
  • 1/2 cup Fresh lime juice(Freshly squeezed only)
  • 1 piece Dried kombu(About 2-inches square)
  • 2 tsp Shiro shoyu (white soy sauce)(Adds umami without darkening our pristine white fish)
  • 1 tbsp Green yuzu kosho(Adjust to your heat preference)
  • 1/4 cup Red onion(Thinly slivered)
  • 1/2 cup Cucumber(Seeded and finely diced)
  • 1 whole Ripe avocado(Halved and pitted)
  • 1/4 cup Cilantro leaves(Roughly chopped)
  • 1 bag Plantain chips(For scooping)
  • 1 tsp Flaky sea salt(To taste)

Instructions

  1. 1

    In a small bowl, combine 1/2 cup fresh lime juice, 2 tsp shiro shoyu (white soy sauce), and 1 piece dried kombu. Let this steep at room temperature. We are infusing the acid with glutamates, which will round out the harshness of the citrus and amplify the natural sweetness of the fish.

    10 min

    Tip: Don't skip the kombu! It's the secret to a Leche de Tigre that tastes layered rather than aggressively sour.

  2. 2

    While the juice steeps, prepare your garnishes. Thinly slice the 1/4 cup red onion, dice the 1/2 cup cucumber, and chop the 1/4 cup cilantro leaves.

    5 min

    Tip: Keep the cucumber pieces small—about the size of a match head—so they distribute evenly in every bite.

  3. 3

    Slice the 1 lb fresh halibut into uniform 1/2-inch cubes. Precision matters here; uneven cuts mean uneven curing, resulting in some pieces being chalky and others remaining entirely raw.

    5 min

    Tip: Make sure your knife is razor sharp to avoid tearing the delicate flesh.

  4. 4

    Remove and discard the kombu from the lime juice. Whisk in the 1 tbsp green yuzu kosho until completely dissolved. This is your Leche de Tigre.

    2 min

    Tip: Yuzu kosho varies wildly in salt and heat by brand. Taste the liquid now—it should be aggressively tangy, salty, and spicy. The fish will absorb and mellow it.

  5. 5

    Place the cubed halibut and slivered red onion in a non-reactive bowl. Pour the yuzu kosho liquid over the top, gently toss to coat, and set a timer for exactly 8 minutes. We want to denature the exterior proteins while leaving a slightly translucent, tender core.

    8 min

    Tip: Curing the onions alongside the fish tames their raw, sulfuric bite.

  6. 6

    While the fish cures, take your 1 whole ripe avocado (still in the skin). Using a kitchen blowtorch, lightly char the exposed flesh to add a hint of smokiness. Scoop out the flesh and dice it.

    3 min

    Tip: If you don't have a blowtorch, simply dice the avocado. Do not attempt to broil it, as it will get mushy.

  7. 7

    When the 8-minute timer goes off, immediately fold the diced cucumber, charred avocado, and cilantro into the bowl. Finish with a sprinkle of 1 tsp flaky sea salt. Serve immediately with 1 bag plantain chips.

    2 min

    Tip: Serve this cold! I like to keep my serving bowls in the freezer until the last second.

Chef's Notes

Why this works: Acid-curing fish is just a chemical way of cooking it. The acid denatures the proteins just like heat does, turning them firm and opaque. But unlike heat, acid doesn't render fat or evaporate moisture. I've found 8 minutes is the absolute sweet spot for firm white fish like halibut—any longer and it becomes chalky. The yuzu kosho replaces the traditional jalapeño and salt of a Mexican aguachile, bringing a deeply fermented, floral chili heat that changes the entire DNA of the dish.
