If nori has turned up in a recipe or caught your eye at the store, here's what you need to use it with confidence and how to choose it, cook it, store it, what to substitute, and 12 recipes to try it in.

What is nori?

Nori is the thin, paper-like sheets of dried, roasted seaweed that wrap sushi rolls and rice balls. It is made from red algae in the genus Pyropia, traditionally called laver, which is shredded, pressed into sheets like handmade paper, dried and toasted.

The flavor is deeply savory and oceanic, a clean wave of umami with a faint sweetness and a whiff of the sea. Toasting darkens the sheet to glossy near-black and brings out a nutty edge.

Crisp from the package, nori turns chewy and soft the moment it meets moisture, which is the whole logic of how you handle it.

How to Use Nori

The headline job is wrapping. Lay a sheet shiny-side-down on a bamboo mat, spread cooled sushi rice over it, then add fillings and roll it up tightly.

You see this in Vegetarian Sushi Rolls, Tuna Maki and Cream Cheese & Crab Sushi Rolls, and in the sashimi-wrapping technique of Isobe Zukuri.

Nori is just as good torn or snipped over food as a finishing garnish. Crumble it onto rice bowls and noodle soups, or over vegetables as in Roasted Brussel Sprouts with Nori, where it adds a hit of savory depth at the end.

Toasted and salted into thin snacking strips, it is eaten straight from the pack.

A quick pass over a flame or a dry pan re-crisps any sheet that has gone limp.

Pairing and Common Mistakes

Nori belongs with the Japanese pantry: short-grain rice, rice vinegar, soy sauce, wasabi, sesame, fresh fish, cucumber and avocado. Its salinity also lifts unexpected partners, from scrambled tofu to roasted vegetables.

The most common mistake is letting nori sit out and go soft before you need it. Once it absorbs humidity it loses its crackle and tears, so keep sheets sealed until the moment you roll.

The second is putting too much wet rice on the sheet, or rolling too slowly. Excess moisture softens the nori to the point it splits, so spread a thin, even rice layer and work quickly while the sheet is still crisp.

What to Use Instead

There is no exact substitute for a nori sheet, because nothing else wraps the way it does.

For sushi specifically, a thin omelet or a sheet of soy paper can stand in as a wrapper, and a large blanched cabbage or chard leaf works in a pinch, though all change the flavor.

For the umami garnish rather than the wrap, other dried seaweeds carry the same oceanic punch. Dulse flakes or wakame both work, as does a sprinkle of furikake seasoning. None of them roll a maki, but they deliver that sea-salt depth onto a finished dish.

Buying and Storing Nori

Nori comes in full sheets for rolling, smaller half sheets, and pre-cut snacking strips, sold in the Asian aisle or at any Japanese grocer. Look for sheets that are dark, glossy and uniform; greenish, dull or pin-holed sheets are lower grade and tear more easily.

Moisture is the enemy. Keep nori in an airtight bag or tin along with the silica packet it came with, stored somewhere cool and dark, where it stays crisp for months.

If sheets have turned soft, a few seconds over low heat dries them out and brings back the snap. Once nori smells stale and fishy or refuses to re-crisp, its day is done.
