Black Lime & Lemongrass-Cured Hokkaido Scallop Bowl
I still remember the afternoon in a tiny Bangkok market when I first crushed a dried Persian black lime alongside fresh lemongrass. That intense, fermented citrus punch hit me with the same deep umami resonance I grew up loving in Tokyo. That flavor collision is everything this bowl is about. When you cure sweet, silky Hokkaido scallops in a hypertonic mix of ground black lime, lemongrass, and sea salt, something magical happens. The salt draws out excess moisture, tightening the muscle while supercharging that ocean-sweet flavor. Pile those glistening rounds over warm coconut-ginger sushi rice, add a crunchy slap of chayote sunomono, and splash it all with a bright calamansi-white shoyu dressing. It is tropical, it is Japanese, and it completely rewrites the rules of raw seafood. My biggest tip? Do not rush the cure. Give those scallops exactly seven minutes—any less and they are just raw, any more and you lose that melt-in-your-mouth silkiness. Play with the heat, swap the chayote for jicama if you are feeling wild, and always, always taste as you go.

Timeline
Ingredients
- 10 oz Hokkaido sea scallops(dry-packed U-10 or U-12, side muscles removed and patted dry)
- 1.5 tsp Fine sea salt(divided; 1 tsp for scallop cure, 0.5 tsp for pickled chayote)
- 1.5 tsp Granulated cane sugar(divided; 1 tsp for scallop cure, 0.5 tsp for pickled chayote)
- 1 tsp Dried black lime powder(finely ground Persian loomi; brings earthy, fermented citrus depth)
- 1 tbsp Fresh lemongrass(tender bottom white bulb only, microplaned or minced very fine)
- 1 tsp Lime zest(freshly microplaned)
- 1 cup Koshihikari short-grain rice(rinsed until water runs clear and drained)
- 1 cup Water(for cooking rice)
- 0.5 cup Unsweetened coconut milk(full fat)
- 1 inch piece Fresh ginger(peeled and cut into thin matchsticks)
- 1 small Chayote squash(halved, seeded, and shaved paper-thin on a mandoline)
- 3 tbsp Rice vinegar(divided; 2 tbsp for chayote pickle, 1 tbsp for dressing)
- 1 tbsp Mirin(for chayote pickle)
- 2 tbsp White shoyu(Japanese white soy sauce, for clean amber hue and delicate umami)
- 2 tbsp Fresh calamansi juice(substitute fresh key lime juice if unavailable)
- 1 tsp Toasted sesame oil(pure Japanese toasted sesame oil)
- 1 Ripe avocado(halved, pitted, and sliced thin)
- 6 Fresh shiso leaves(torn or thinly chiffonaded)
- 1 tsp Japanese chili oil (rayu)(for finishing drizzle)
- 1 tsp Toasted sesame seeds(blend of black and white)
Instructions
- 1
In a small heavy-bottomed saucepan, combine 1 cup Koshihikari short-grain rice, 1 cup Water, 0.5 cup Unsweetened coconut milk, and 1 inch piece Fresh ginger. Bring to a boil over medium-high heat, cover immediately with a tight lid, reduce the heat to the lowest setting, and simmer for 15 minutes. Remove from heat and let sit covered off the flame to steam for 10 minutes.
25 min
Tip: Do not peek or lift the lid during the rest period; the trapped residual steam is crucial for evenly plump, velvety grains.
- 2
In a small ramekin, mix 1 tsp Fine sea salt, 1 tsp Granulated cane sugar, 1 tsp Dried black lime powder, 1 tbsp Fresh lemongrass, and 1 tsp Lime zest until aromatic and sandy. Gently dredge 10 oz Hokkaido sea scallops in the cure mixture, ensuring all surfaces are lightly and evenly coated.
5 min
Tip: Microplaning the lemongrass bulb ensures it releases its essential oils directly into the curing salt without leaving tough woody bits.
- 3
Transfer the coated scallops to a parchment-lined plate and place them uncovered in the refrigerator to cure undisturbed for 15 minutes.
15 min
Tip: Keep them uncovered so the cold circulating air helps dry the exterior, amplifying the osmotic moisture draw.
- 4
While the scallops cure, place 1 small Chayote squash in a bowl with remaining 0.5 tsp Fine sea salt, remaining 0.5 tsp Granulated cane sugar, 2 tbsp Rice vinegar, and 1 tbsp Mirin. Massage gently with your fingers for 30 seconds and let sit at room temperature to quick-pickle.
5 min
Tip: Slicing chayote paper-thin breaks down its fibrous crunch into an exceptionally crisp sunomono pickle in mere minutes.
- 5
In a small mixing bowl, whisk together 2 tbsp White shoyu, 2 tbsp Fresh calamansi juice, remaining 1 tbsp Rice vinegar, and 1 tsp Toasted sesame oil until emulsified into a fragrant, golden dressing.
3 min
Tip: White shoyu gives all the savory glutamic richness of dark soy sauce without discoloring the luminous white scallops.
- 6
Remove the scallops from the refrigerator. Quickly dip each scallop into a bowl of ice-cold water for 2 seconds to rinse off surface grains, then immediately blot completely dry on paper towels. Using a very sharp slicing knife, slice each cured scallop horizontally into 3 thin, translucent rounds.
5 min
Tip: Slice in single, smooth drawing strokes from heel to tip of the knife without sawing to preserve the scallop's glass-like edges.
- 7
Fluff the warm coconut-ginger rice and divide it between two wide shallow lunch bowls. Fan the sliced cured scallops over one side of the rice. Arrange 1 Ripe avocado slices and drained pickled chayote alongside. Spoon the calamansi-white shoyu dressing generously over the scallops and avocado. Garnish with 6 Fresh shiso leaves, 1 tsp Japanese chili oil (rayu), and 1 tsp Toasted sesame seeds.
5 min
Tip: Assemble just before eating so you capture the sensory contrast between the warm coconut rice and the cool, silky cured scallops.
Chef's Notes
Why this works: Fresh Hokkaido scallops (hotate) contain high amounts of natural glycine, which gives them their candy-like sweetness, but their high water content (nearly 80%) can dilute their impact when served raw. By applying a hypertonic dry cure of salt and cane sugar with acidic, fermented black lime (loomi) and lemongrass, we initiate rapid osmosis. In exactly 15 minutes, the scallops expel roughly 6% of their surface and intracellular water. This tightens their delicate actin and myosin protein filaments, transforming the texture from soft to an elastic, toothsome bite reminiscent of top-tier sashimi-grade tataki, while the sour funk of Persian loomi amplifies the shellfishes' natural marine sweetness.

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.
