What is Dashi?
Dashi is a characteristic broth in Japanese cuisine, playing an important role in creating the distinctive “umami” flavor. This broth is the foundation of many traditional dishes, from miso soup, clear broth soup, noodle broth soup, to stews. In addition, dashi is also mixed into the batter for grilled dishes such as okonomiyaki and takoyaki, contributing to the unique flavor of each dish.
Sweet and light dashi can be made with a variety of ingredients from vegetables such as mushrooms, radishes, seaweed, and carrots, providing a large amount of vitamins, minerals, and fiber. Therefore, the product is highly appreciated in weaning menus for young children, contributing to supplementing the necessary nutrients for the baby’s development.

Instructions
Step 1: Prepare the Kombu Seaweed
- Clean the kombu: First, please note that you should not wash the kombu seaweed as this can remove its natural minerals. Instead, use a damp cloth, preferably one with a little sake, to wipe the surface of the kombu clean.
- After cleaning, cut the kombu into medium-sized short pieces.
- Soak the kombu: Put the kombu pieces in 1000ml of cold water and soak for about 1 to 4 hours, or preferably overnight. Soaking the kombu will help the sweet and nutritious substances in the seaweed to be completely released into the water, creating the characteristic flavor for the dashi broth.

Step 2: Cook the Dashi Broth
- Once the kombu has softened, pour the entire soaking water and kombu leaves into a pot.
- Then, put the pot on the stove and bring it to a medium heat.
- When the water starts to simmer, immediately remove the kombu from the pot.
- After removing the kombu, add all the dried bonito flakes to the pot and boil for about 3 to 5 minutes, then turn off the heat.
- Finally, strain the dashi broth through a sieve to completely remove the bonito flakes, keeping only the clear and lightly sweet dashi broth.
💡 Quick Tip:
- Do not cook kombu for too long: Cooking kombu for too long can make the broth bitter and cloudy, affecting the quality of the broth.
- Soak kombu in cold water and start cooking from cold water: helps to extract the maximum umami flavor and minerals without losing the light sweetness or causing bitterness to the broth.

- Add all the prepared vegetables to the pot of water.
- Turn on the heat and bring the water to a boil.
- Once boiling, reduce the heat to low and continue simmering for another 20 minutes.

💡 Quick Tip: Reducing the heat for 20 minutes after boiling helps the vegetables release all their sweetness.
Step 3: Finish
- Turn off the heat and use a spoon to remove all the vegetables from the pot.
- Strain the broth through a sieve to remove any residue and make the dashi clear.

Incompatible Vegetables When Making Dashi Broth
Some vegetables, while offering many health benefits when used individually, can create unwanted reactions when combined, affecting the flavor and even the health of the consumer:
- Potatoes, sweet potatoes, and tomatoes: Although all three of these vegetables are nutritious, combining them can negatively affect the digestive system, leading to indigestion, bloating, or even diarrhea.
- Pumpkin and spinach: Pumpkin and spinach are both rich sources of vitamins and minerals. However, when cooked together, enzymes in pumpkin can reduce the vitamin C content in spinach, significantly reducing the nutritional value of both vegetables.
- Carrots and white radishes: Combining carrots and white radishes can lead to a decrease in each other’s nutritional value. Especially for children, this combination can cause digestive issues such as indigestion and discomfort.
