Gamtae Avocado Shrimp Salad

Blanching the shrimp for exactly two minutes and plunging them immediately into cold water keeps the exterior springy while preserving a moist, tender interior - longer cooking makes them rubbery and dry. The dressing of lime juice, soy sauce, olive oil, and honey layers sharp citrus acidity against soy umami, cutting neatly through the richness of the avocado rather than letting it weigh down the bowl. Gamtae seaweed absorbs moisture rapidly and turns limp within minutes, so it must be crumbled over the salad only at the very moment of serving to retain its crunch and oceanic fragrance. Thinly sliced red onion should be rinsed briefly in cold water to remove the raw, sharp edge, letting it blend more quietly with the other ingredients. Domestic gamtae has a finer, more delicate structure than regular dried laver, so it crumbles cleanly by hand without any tool.
