When was the last time you’ve tasted a dish that had all the distinctive flavors and it instantly became your favorite meal?
A few moments in your life you say? I know exactly what you mean!
In this article, we’re going to talk about the Dashi stock (broth) that brings out the best in almost every meal you mix it with.
In this post we'll cover:
What is Dashi?
Dashi (出汁 in Kanji and だし Katakana) is a class of soup and cooking stock used in Japanese cuisines.
Dashi is the foundation of miso soup, for clear broth, noodle broth and various kinds of stews that help enhance umami.
Umami is one of the five basic tastes that our taste receptors resonate with instantly.
This makes Dashi a very rare discovery that is also a key component for many kinds of recipes.
Dashi also has other names like sea stock or vegetable stock and is actually an all-purpose vegetable-fish broth.
It is the kombu (sea kelp) that is the primary ingredient for Dashi, which has been dried and cut into thin long sheets and is what causes the umami flavors of the miso soup to concentrate.
Dried mushrooms and sometimes even dried sardines are added to the stock as well which really elevates the Dashi stock to new heights!

Why is Dashi So Important?
Dashi is the embodiment of umami, the fifth taste (after sweet, sour, salty, and bitter) that was identified in 1908 by the Japanese chemist Kikunae Ikeda.
Well-known Japanese chef Kiyomi Mikuni spoke about Dashi in a talk show that the Japan Society was hosting a while back
He said that the authentic Dashi made by using kombu with katsuobushi does not only contain the glutamic acid for the umami isolated by Ikeda, but also the inosinates that come from the katsuobushi.
Mikuni pointed out the new research that shows glutamates and inosinates interact in a much deeper and intricate level than just being additives in the Dashi stock.
Thus exhibiting 8 more flavors when used in a mixture than by themselves separately.
Another chemical compound that has a similar multiplicative effect on taste when eaten with the Dashi stock is called guanylates, and this is found in shiitakes and kinoko mushrooms, that are also often used in making dashi.
Because of this, Dashi can be considered as an all-purpose flavor enhancer like we’ve talked about earlier and is essential in a wide variety of Japanese savory dishes that you can find in a lot of their recipes.
However, chefs and cooks treat the katsuobushi and kombu differently when they prepare meals, so the taste of the Dashi may vary from recipe to recipe as well.
Great Dashi Recipes to Try at Home

- Remove the tofu from the microwave oven and place it in another clean plate once again, then let it dehydrate.
- Place a small saucepan on the stove and pour in the Dashi stock, mirin and soy sauce, then turn on the stove to medium heat until the sauce mix gets warm enough. Now turn off the stove and cover the saucepan with a lid.
- Pour cooking oil in a nonstick frying pan and fill it at about 1/4 to 1/2 of an inch and set the heat to 171.11 – 176.67 °Celsius. Put in the tofu slowly and deep fry them for about 5 minutes or until they become golden brown in color.
- Once done then transfer the tofu to a clean plate lined with paper towels to drain the oil off of the tofu. Garnish the tofu with chopped scallion and grated daikon, then pour some sauce on the top to finish.

Chawanmushi (Japanese Egg Custard)
- 1 cup of warm water
- 3/4 teaspoons hon-dashi, or dry Dashi powder
- 4 small dried shiitake mushrooms
- 1/4 cup hot water
- 1/2 teaspoon soy sauce
- 1/2 teaspoon mirin
- 4 medium shrimp, peeled and deveined
- 4 thin slices of kamaboko
- 4 mitsuba leaf stems
- 2 eggs
- Pour 1 cup of warm water and the Dashi powder into a large mixing bowl and mix thoroughly.
- Next step is to soak the shitake mushrooms in a 1/4 cup of hot water in a small bowl and wait for the mushrooms to soften (this may take a few minutes).
- Cut the mushrooms into thin slices and save the 1/4 cup of hot water that you soaked the mushrooms with for later use.
- This time pour the mushroom soaked water into the Dashi stock; add the mirin and soy sauce and then mix them thoroughly.
- Blanch the shrimp in hot water for 30 seconds and then divide them evenly into 2 teacups (or ramekins of about 230 ml each).
- Divide up the mitsuba, kamaboko, and mushrooms even as well, then save a very thin slice of each of the kamaboko (about 1/8th of an inch thick) and allow it to float on the top of the dish to add color to the cuisine.
- Crack the eggs in a separate mixing bowl and whisk them until they become frothy. Pour in the Dashi as well and mix them thoroughly, then pour it over a strainer and put the resulting liquid into the individual teacup leaving a space about half-an-inch at the top.
- Season it with what’s left of the kamaboko (optional).
- Get a large metal pot and pour water into it until it fills the pot with 2 inches of water from the bottom. Turn on the stove and heat up the water until it reaches its boiling point, then place the teacups/ramekins in the pot, but make sure that the water is at least an inch lower than the rims of your ramekins so that it won’t sip through and contaminate the ingredients.
- Place an aluminum cover over each ramekin so that steam won’t also get into the cup. Reduce the temperature to medium-low, cover the pot with a lid, and then steam the ingredients for about 10 – 15 minutes, or until it becomes tender or cooked.
- To test, stick a chopstick or toothpick through; if the liquid is clear, it’s ready to eat.
