For Dishes With High Transparency And For Soup Stock

Rishiri kombu kelp does not add color to the soup stock, so it is often used in Kansai cuisine, where the color of the ingredients is important.

Rishiri kombu kelp, which is a favorite at restaurants and vegetarian restaurants in Kyoto, is suitable for simple minimalist Japanese cuisine. In addition, the umami of Rishiri kombu kelp, which has no peculiarity, makes it a solid foundation for cooking as a soup stock.

Use It To Make Kombu Based Stock (Kombu Dashi)

The colorless and transparent Rishiri kombu stock, which won’t make you worry about the color, is perfect for cooking that makes use of the colors of the ingredients such as yudofu and soup.

Tofu And Egg Soup

70g Silken Tofu
1 Beaten Egg
300ml Kombu Stock (Kombu Dashi)
2 tsp Light Soy Sauce
A little salt

1. Put kombu stock in a pan and heat it over medium heat. Just before boiling, reduce the heat to low and add the cubed silken tofu.

2. Turn up the heat, pour beaten egg all over so that it spreads throughout the soup.

3. Add light soy sauce and salt to season, and it's done.

Miso soup tends to be the most popular soup on the table, but with Rishiri kombu kelp, soup with a beautiful clear color can be an option that you can enjoy with a wide variety of ingredients.

Use The Dried Kombu Kelp As It Is

If you add it to the pickles that accompany your daily meals, you enjoy a mellow taste that complements other ingredients in the pickle.

The goodness of Rishiri kombu kelp can be especially utilized for pickles that make use of the plump and beautiful light color of radish and turnip.

Cook The Leftover Kombu After Extracting The Stock

Rishiri kombu kelp is characterized by being harder in texture than other kelp.
If the texture is too strong to make tsukudani (stir fry seaweed simmered in vinegar and soy sauce), you can add vinegar from the beginning to make it softer. You can also enjoy it by roasting or frying.

* Please note that the oil will splash if the kelp contains water.

Kombu Tsukudani (Seafood or seaweed simmered in soy sauce and mirin)

60g Rishiri Kombu
300ml Water
2 tbsp Vinegar
2 tbsp Sake
2 tbsp Sugar
2 tbsp Soy Sauce
2 tbsp Mirin

1. After extracting the kombu dashi stock, chop the leftover kombu sheets, and put it into a pot.

2. Add water and vinegar. Cook over medium heat. When it boils, add sake, sugar, soy sauce and mirin. Simmer on low heat for 30 minutes.

3. Simmer until the water is gone and you're done.

If you only have a small amount of leftover kombu after making kombu dashi stock, you can cut it into small pieces and store it in the freezer for the time being. You can thaw it and make tsukudani after you have saved enough leftover kombu.

Alkaline Food Rich In Nutrition That Makes The Body ‘Happy’

Today's modern diet, which mainly contains acid forming substances such as meat, carbohydrates, sugar and processed foods, can lead to illness and aging.

Kombu kelp is called the strongest alkaline food, and helps keep the body healthy. Since it covers most of the essential minerals and is rich in nutrition, it is ideal to consume not only the soup stock from kombu, but also the kombu itself.

Kombu Health Benefits

Abundant Dietary Fiber, Perfect For Gut Health

Kombu kelp contains alginic acid and fucoidan, which are water-soluble dietary fibers distinct to seaweeds, and when soaked in water, they dissolve and become sticky and thick.

Including insoluble dietary fiber, it contains about 5 times as much dietary fiber as burdock. It is also recommended for those who tend to suffer from stomach sickness and those who aim to have healthy body weight.

Kombu Health Benefits

For those who want to refresh their stomach and keep their hair healthy, we recommend kelp water, which allows you to easily ingest fucoidan, a dietary fiber peculiar to seaweed.

Rishiri Kombu Water (Kombu Tea)

1.5L Water
20g Kombu Kelp

1. Cut about 20g of kombu kelp to a width of about 5mm, put it in a storage container, and add 1.5L of water.

2. Store in the refrigerator, and after 8 hours to 1 day, the stickiness will dissolve in the water.

* Please drink during 2 weeks period. The proper amount to take kombu water is one glass per day.

Kombu Kelp Water

The kombu kelp water, where the abundant nutrients of kombu kelp are dissolved, is also called ‘water of life’ and is a reassuring ally for daily health maintenance and beauty purposes.

You can drink it as it is or use it as a soup stock for cooking.

Strengthen Your Body With The Power Of Calcium

The amount of calcium contained in kombu kelp is 6 times that of milk.

Moreover, it is known that the calcium contained in seaweed is of higher quality than that of dairy products, is easily adapted to the human body, and has a high digestion and absorption rate.

Calcium is a nutrient that the body cannot produce, but using kombu kelp in your daily diet can prevent calcium deficiency.

Kombu Health Benefits

Eliminate Iron Deficiency And Make Your Body Less Tired

Kombu kelp contains about three times as much iron as spinach, and can be immediately incorporated as an ingredient to improve the basic strength of the body that tends to be easily tired.

Kombu Health Benefits

Iodine, An Essential Ingredient For Maintaining Good Health

Iodine is also related to the production of growth hormone, so it is an important nutrient for those who are worried about physical disorders and children who are in a period of physical and mental development. Iodine is one of the essential minerals, and taking it little by little every day helps maintain good health.

By eating kombu kelp together with soybean-based foods, the effect of saponin inside the soybeans that can help improve blood circulation will be strengthened. The recommended way to eat kombu kelp and soybeans is through traditional Japanese cooking like miso soup or yudofu.

We only handle the highest quality kelp, grades 1 and 2. The taste, umami, and characteristics of each kombu kelp are completely different.

We hope that you will find your favorite kelp by using it according to your uses.
