Expiration & Storage Tips
When does nori seaweed expire?
In its unopened original packaging, nori seaweed should stay fresh for about one to two years past the date printed on the label. However, once the packaging is opened, it's best to consume it within a few weeks to enjoy its peak flavor and crispiness. Although it doesn't strictly 'expire' and become unsafe to eat, the texture and flavor will diminish over time, especially if not stored correctly. For homemade sushi or other dishes using nori, try to consume within a day or so for the best taste. Nori can be frozen for up to a month without significant loss of quality.
How do you tell if nori seaweed is bad?
With nori seaweed, the first sign that it's past its prime is usually a change in texture. Fresh nori should be crisp and break apart easily, but as it ages, it may become bendy and rubbery. The color might also fade, and it could develop a distinctly stale, fishy smell. Another sure sign is the presence of mold, which could appear as fuzzy green or white patches on the surface. While nori doesn't typically spoil in a way that would make you sick, these changes mean it's time to toss out the old package and get a new one. Whenever in doubt, it's better to be safe and discard any questionable nori.
Tips for storing nori seaweed to extend shelf life
• Always store your nori in a cool, dark, and dry place. Keeping it in a tightly sealed container can help maintain its freshness, flavor, and crispiness longer.
• Once you've opened the package, try to use it up within a few weeks, even if you're storing it properly. The texture and flavor are at their best when the nori is fresh.
• If you don't think you'll finish it in time, you can also freeze the nori. Just wrap it tightly in plastic wrap or put it in a freezer-safe zip-top bag and put it in the freezer. When you're ready to use it, let it defrost at room temperature for a few minutes, and it should be good to go.
• If you live in a humid area and find your nori gets soggy quickly, try storing it with a packet of silica gel (the kind found in shoe boxes) to help keep it dry. Just make sure not to eat the packet!
