Thick First Grade Natural Hidaka Kombu, Grown By The Rough Seas

Hidaka Kombu Kelp

Hidaka kombu kelp from the Hidaka region in Southern Hokkaido has a unique flavor that is unique to kelp. Moreover, the soup stock derived from Hidaka kombu kelp is well-suited for various dishes.

From hot pot to soup, you can use this kombu kelp to make the stock base for everyday cooking. Because the kombu is thick and does not crumble easily, you can enjoy a nice bite and texture even when it is boiled.

Hidaka kombu is kombu kelp that is popular with many people because of its reasonable price and reliable quality. It is also used as an ingredient in commercially available rice balls in Japan.

First Grade Rishiri Kombu: Characterized By Elegant, Beautiful, And Clear Soup Stock With No Peculiar Taste

Rishiri Kombu Kelp

Rishiri kombu kelp is harvested in the coasts of Rishiri Island, Rebun Island, and Wakkanai in northern Hokkaido.

It features a fragrant and elegant soup stock, and it is colorless and transparent, so you don't have to worry about the color transfer to the dish.

It is often used in restaurants and vegetarian dishes, as well as yudofu (boiled tofu) and soup. Rishiri is kombu kelp with a gentle taste that is not too assertive and enhances the taste of other ingredients.

The Rich Prominent Taste of Rausu, The King of Kombu

Rausu Kombu Kelp

Rare Rausu kombu kelp that grows only in the Rausu area on the south side of the Shiretoko Peninsula, which is particularly rich in minerals and other nutrients, is known as the ‘King of Kombu’ and is widely known as high-class kombu kelp.

It is softer and more palatable than other kombu kelp, so it is delicious even if you eat it as it is in a dry state. You can also use Rausu to make kombujime, a technique to preserve ingredients by keeping them between kombu sheets. Rausu will increase the taste of sashimi and vegetables while also keeping the original taste of the ingredients.

Rausu kombu kelp produces a rich, fragrant, golden-colored soup stock that plays a leading role in the flavor of hot pot dishes and noodle dishes.

Use It To Make Kombu Based Stock (Kombu Dashi)

Once you know how to make the basic kombu stock, you can apply its flavor to various dishes.

It is recommended not only to use it for soup and simmered dishes, where the soup stock plays a leading role but also to add richness and umami to stir-fried dishes.

Kombu stock can be refrigerated for a few days and frozen for longer, so it will save you time if you make them in one big batch.

15g Sugar
A little Red pepper
5 cm Kombu Kelp (cut into small pieces)

Recipes With Rausu Kombu

Rausu Kombu Kelp

Kombujime (Kombu Cured Sashimi)
Ingredients (For 2 People)

Appropriate Amount Rausu Kombu Kelp
Appropriate Amount Sashimi
Appropriate Amount of Raw Vegetables (Cucumbers, Carrots, Chinese Cabbage, Turnips, Etc.)
Appropriate Amount Salt

1. Prepare two pieces of kombu kelp in the appropriate size to sandwich the ingredients from above and below. Lightly clean the surface of the kombu sheet with a dry cloth and place it on top of plastic wrap. Sprinkle a little salt on it, arrange the bite-sized sashimi and vegetables that are thinly cut, make sure they do not overlap. Sprinkle a little salt on the ingredients and cover it with another kombu sheet.

2. Wrap it in a tight wrap so the kombu sheets are properly sticking to the ingredients. Put a weight on it, and let it sit in the refrigerator for 1 hour or more.

If you let it sit in the refrigerator for a short time, the kelp will scent softly and elegantly. The longer you let it sit, the more you can enjoy the strong umami that has absorbed into the ingredients that have become moist and squeezed.

* When tightening sashimi with kombu, please eat it as soon as possible.

Cook The Leftover Kombu After Extracting The Stock

It is especially recommended to cook kombu kelp after extracting the stock from it. One of the best ways to cook it is to simmer it with vinegar and soy sauce (Tsukudani)i, which makes the best use of the softness of simmered kombu kelp.

By eating whole kombu kelp, you can also ingest nutrients that are not extracted into the kombu stock.

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

60g Leftover 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 them 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.

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.

Frequently Asked Questions

I heard that kombu kelp is good for your health, is that true?
Kombu kelp is a strong alkaline food that is good for people with a modern lifestyle that tend to be unhealthy. It is also rich in calcium, minerals, dietary fiber, and vitamins.

I heard that eating too much kombu kelp is dangerous, is that true?
Dietary fiber and iodine contained in kelp have a strong effect, so if you take too much every day, it may cause stomach and thyroid disorders.
