Buying seaweed: how to choose the right snack, salad or wakame

If you want to buy seaweed, you’ll soon notice a wide range of shapes, flavours, pack sizes and preparation methods. A crispy Korean seaweed snack is very different from dried wakame for soup, while a chilled or frozen seaweed salad needs to be stored differently again.

The product name alone doesn’t tell you enough. Think about what you want to use it for, check how much salt and sugar it contains, and make sure you know whether it’s ready to eat.

Common pitfalls when buying seaweed

1. Confusing dried seaweed with a ready-to-eat product

Dried seaweed usually needs to be soaked first, and sometimes blanched or boiled. So a product called wakame could be either a dried ingredient or a ready-to-eat salad.

Dried wakame is handy for soup, hotpot and stir-fries because you can store it at room temperature. A wakame salad, on the other hand, is meant to be served straight after defrosting. Always check the instructions before you order.

2. Looking only at the amount of seaweed

Seaweed snacks often contain oil, sugar, flavour enhancers, vinegar, chilli or other seasonings too. That’s not necessarily a problem, but it does affect the flavour and nutritional value.

According to the product specifications, Wei Long Fengchi Kelp is 76% kelp and contains 8,23 grams of salt per 100 grams. Bestore Undaria Pinnatifida contains 2.850 milligrams of sodium per 100 grams, according to the nutrition information provided. So compare the label per 100 grams, rather than looking only at the pack size.

3. Overlooking storage instructions and allergens

A frozen seaweed salad should stay frozen until you’re ready to use it. After defrosting, keep it chilled and don’t refreeze it, according to the product information. A dry pack, by contrast, needs to be kept somewhere cool and dry, away from moisture.

Check for allergens too. Various seasoned products may contain soya, sesame, mustard, wheat, gluten and fish. Check the packaging when your order arrives, as the current label and preparation instructions should always take priority.

The key things to check

1. Choose the right form for how you’ll use it

  • Seaweed snack: ready to eat straight from the pack, often seasoned or roasted. Handy for a small portion with lunch or as a crunchy topping.
  • Seaweed salad: ready to use after defrosting. Goes well as a side dish with sushi, rice, noodles or an Asian meal.
  • Dried wakame: soak first and, depending on the product, blanch or simmer. Suitable for soup, hotpot, salads and stir-fries.
  • Kelp or Chinese seaweed snack: often firmer in texture and boldly seasoned, for example with chilli, Sichuan pepper or mustard.

So if you want to buy a seaweed snack, decide first whether convenience or versatility matters most to you.

2. Check the ingredients, flavour and allergens

A simple dried variety may contain just seaweed and salt. Seasoned products often have a longer ingredients list. Check for:

  • the percentage of seaweed;
  • added oil and sugar;
  • chilli, vinegar, mustard or Sichuan pepper;
  • flavour enhancers and preservatives;
  • allergens such as soya, sesame, mustard, wheat and fish.

A spicy variety won’t necessarily suit every dish. A strongly seasoned wakame salad, for example, could overpower the flavour of a mild soup.

3. Check the packaging and storage method

Net weight can vary considerably. A 20 or 50 gram pack is a good size to try, while a 1 kg pack makes more sense for families, catering-style use or anyone who regularly cooks Asian dishes.

Before ordering, check:

  1. Is the product dried, chilled or frozen?
  2. Is it ready to eat, or does it need to be prepared first?
  3. How long can you keep it after opening?
  4. Is there a specific use-by date on the packaging?
  5. Is the pack size right for your household?

Frequently asked questions about seaweed

Is seaweed ready to eat?

That depends on the type of product. Seasoned laver snacks and many ready-made salads can be eaten straight away, according to the product description. Dried wakame needs to be soaked first and sometimes briefly blanched or boiled. Always follow the instructions on the packaging.

How should I store seaweed salad?

Keep frozen seaweed salad in the freezer until you’re ready to use it. After defrosting, keep it in the fridge and use it within the stated period. Don’t refreeze it. Shelf-stable seasoned snacks should generally be stored somewhere cool and dry, out of direct sunlight.

What should I look for in the nutritional information?

Compare salt, sugar and fat per 100 grams, as well as the proportion of seaweed. Seasoned snacks and salads can have quite different nutritional values from a simple dried variety because of the oil, sugar and seasonings they contain. If you eat seaweed regularly, you can also follow any guidance on the packaging about moderation and iodine.
