How to Reconsititute Hijiki – Recipe for Hijiki and Spiral Cut Carrot Salad and Sesame Pineapple Dressing

Hijiki is a marine seaweed that is found at specialty markets in its dried form. It can be reconstituted and used in many recipes, like salads and soups.

Reconstituting Dried Hijiki

  • A 2 oz. portion of dried hijiki roughly needs about 1 1/2 to 2 quarts of water. Place hijiki in a large bowl, add water to cover and let soak for about 30 minutes.
  • Drain in a colander or a sieve to remove the soaking water, pressing on the seaweed to release any extra water. Rinse again in cold running water, and drain thoroughly.
  • It is ready to be used in recipes. Hijiki swells to about 2 to 3 times the volume of dried hijiki when properly soaked.

Write a review
  1. 1 2-ounce package of dried hijiki seaweed
  2. 3 large green onions, sliced on the diagonal (green and white parts)
  3. 2 cups spiral cut carrots, or thinly sliced carrots, see step 2 below
For the Sesame Pineapple Dressing
  1. 4 1/2 tablespoons seasoned rice vinegar
  2. 2 tablespoons toasted white sesame seeds
  3. 1 tablespoon sesame oil
  4. 2 tablespoons pineapple juice
  5. 1 1/2 teaspoons sugar
  6. 1 teaspoon soy sauce
  7. 1/2 teaspoon salt
  1. For Dressing: Mix all the ingredients together in a mixing bowl. Use for the hijiki salad.
  2. Place the hijiki in a large mixing bowl. Add about 1 1/2 to 2 quarts of warm water over and mix. Let set uncovered for about 30 minutes, to reconstitute the dried seaweed. Once soft, drain in a colander or a sieve, and rinse with water. Drain again thoroughly and place in a mixing bowl for the salad. Add the green onions.
  3. Spiral cut the carrots: Using a spiral slicer, spiral-cut 3 to 4 inch lengths of carrots, enough to make 2 cups. If the spirals are very long then break up the lengths into smaller pieces. If no spiral slicer is available, simply cut the carrots in half and slice thinly on the diagonal. Use 2 cups of sliced carrots for the recipe. Top the vegetables with the Sesame Pineapple Dressing, and toss to coat. Serve cold.

What is Hijiki? All About the Black Seaweed Used in Macrobiotic and Healthy Cooking

Hijiki, Hizikia fusiforme, is a seaweed which a plant that grows in marine or saltwater. Hijiki is also known as ‘hiziki’. While it comes in different forms, it is most commonly identified as a black, finely shredded-looking seaweed that is sold dried and sealed in packs. Hijiki is found with other dried seaweed varieties and is found in specialty and Asian supermarkets. Hijiki is stored at room temperature similar to other dried seaweed.

This black vegetable is a staple ingredient in macrobiotic cooking, and is often served as a vegetable by itself. It can be served with other vegetables, such as cucumbers, carrots and shredded lettuces as a salad, or served by itself with a flavorful dressing and sesame seeds.

Hijiki is a high-fiber food: a 10g dried portion contains 6 g fiber (or 22% daily values for fiber). It is also a good source of iron, calcium, and is fat-free. The same 10g dried portion has 40% and 10% daily values respectively for iron and calcium.

Inorganic and Organic Arsenic Levels in Hijiki

While many people enjoy hijiki in salads, soups and as an ingredient used in appetizers, some governmental agencies have placed notice to their citizens of limiting the amount of hijiki consumed or of avoiding it all together. New Zealand, Canada, the United Kingdom and Hong Kong are countries or areas with restrictions or have official notices for the limited use of hijiki as a food product for consumption.

Hijiki is singled out as the only seaweed used for cooking that contains high levels of inorganic arsenic. Arsenic is an element found in nature. Organic and inorganic arsenic is found in much of the seaweed used for cooking, including kombu, wakame and nori. Some governmental agencies, such as the Department of Health and Human Services Agency for Toxic Substances and Disease Registry, have found organic arsenic to be less toxic than inorganic arsenic.

As for the safety of using hijiki in cooking and eating it as a food source, every individual must make an independent decision and use their governmental agencies as guides. Soaking dried hijiki and draining it well afterwards does lower the total amount of inorganic arsenic that the hijiki contains. And hijiki is never served in its dried form, which contains the highest levels of inorganic arsenic of all seaweed.
