Dried Seaweed
Dried seaweed covers a range of dehydrated sea vegetables, most commonly nori, kombu, and wakame, used across East Asian cooking for wrapping, broth-making, and salads, prized for deep umami and mineral flavor.
How to buy
Choose the type based on use: toasted nori sheets for sushi and snacking, kombu, a thick, dark kelp, for dashi and braising, and wakame for soups and salads. Look for sheets that are crisp, uniformly dark, and not torn or faded to brown, which signals age or moisture exposure.
How to store
Keep tightly sealed in an airtight bag or container, with a desiccant packet if included, away from humidity, which quickly turns crisp nori soft and chewy. Store in a cool, dry pantry, and refrigerate or freeze opened nori for longer freshness in humid climates.
Culinary profile
- Flavor
- Deeply savory and oceanic with a pronounced umami depth from natural glutamates, especially in kombu. Nori is more delicate and slightly sweet, while wakame has a mild brininess.
- Texture
- Nori is thin, crisp, and almost papery dry, turning slightly chewy once it absorbs moisture from rice or broth. Kombu is thick and leathery dry, softening as it simmers, while rehydrated wakame turns silky and slippery.
- Aroma
- A briny, oceanic aroma, most pronounced in kombu, which also carries a faint underlying sweetness.
How to prepare
- Toasted and wrapped — Used whole as a wrapper for sushi rolls and rice balls.
- Simmered for broth — Kombu steeped or simmered gently to extract umami for dashi.
- Rehydrated for salad — Wakame soaked in water to soften before dressing with vinegar and sesame.
- Crumbled as garnish — Torn or shredded nori sprinkled over rice, noodles, or popcorn.
