When was the last time you’ve tasted a dish that had all the distinctive flavours and it instantly becomes 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.
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 is also important in creating the batter (flour-based paste) of grilled foods such as the takoyaki and okonomiyaki.
Dashi also has other names like sea stock or vegetable stock is actually an all-purpose vegetable-fish broth. It is the kombu (sea kelp) that is the primary ingredient for the Dashi, which has been dried and cut into thin long sheets and is what causes the umami flavors of the miso soup to concentrate.
In order to further enhance the Dashi stock smoky katsuobushi, shavings of dried, smoked, and sometimes fermented skipjack tuna or bonito is added. 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 the Dashi in a recent talk show hosted by the Japan Society. He said that the typical Dashi made from kombu and 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 tasted like 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 present in mushrooms like shiitakes and kinoko.
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 katsuboshi 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
- One 14-ounce package regular tofu (momen tofu)
- 1 cup Dashi stock
- 2 tablespoons soy sauce
- 2 tablespoons mirin
- 1/2 cup cornstarch
- Vegetable oil, for frying
- One 1-inch piece daikon, grated
- 1 scallion, chopped
- Katsuobushi (bonito flakes), for garnish (optional)
- Shichimi (Japanese chile flakes), for garnish (optional)
- After soaking the tofu with water for 5-10 minutes, drain the water over the sink, Cut it into 6-8 pieces of cubes and transfer to a clean plate, then microwave it for 3 minutes on high settings.
- 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.
- Garnish with bonito flakes and Japanese chile flakes, if desired.

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.

- Put the saucepan on top of the stove, fill it with water and out the pork belly in. Turn on the heat and set to high, then bring to a boil. Simmer for 10 minutes.
- Remove the scum that floats on the water surface with a skimmer. Turn off the stove and remove the pork belly. Rinse with running water and then use paper towels to pat them dry.
- Replace the water in the saucepan with a clean one and boil the pork belly in it once more for another 30 minutes. Remove and rinse the pork once more and then pat dry with paper towels again as you did before. This time cut the pork belly into thick slices.
- Rinse the saucepan and make it ready for another round of cooking. Pour the sake, mirin and the soy sauce into the saucepan, then toss the spring onion, ginger and garlic as well.
- This time add the pork into the saucepan along with the other ingredients and simmer it until much of the liquid has evaporated leaving only a sticky sauce that makes the pork cuts look glossy. Turn off the stove and set the pork mix aside for later use.
- For the dashi stock, wipe the kombu with a damp cloth or paper towel, then cut slits (at about 2 cm intervals) along the kombu.
- Get a new clean saucepan, pour water in it and place the kombu in the water, then bring to boil. After 2-3 minutes turn off the stove and remove the kombu and place it in a clean plate.
- Boil the bonito flakes in water too! Do this for about 30 seconds, turn off the stove and then wait for the bonito flakes to sink to the bottom of the pot (This should take about 10 minutes).
- Get a fine sieve strain (you may want to place paper towels over it to filter the liquid further) and pour the liquid from the bonito flakes that you’ve boiled earlier, then extract all the liquid.
- Boil the udon noodles for about 8-10 minutes until it becomes firm to the bite. Drain the hot water and rinse the noodles in cold running water.
- Divide the udon equally between 2 large serving bowls.
- Boil some water in a small pot. Use an egg piercer or a small pin to pierce the base of the egg and place it in the water. Stir regularly and cook for 6 and 1/2 minutes.
- Turn off the stove and remove the egg from the pot, then place it in a small bowl filled with cold water. Peel off the shell and then cut the egg in half, then set aside for later use.
- This time boil the Dashi stock in a large saucepan, reduce heat to simmer and add the mirin, soy sauce, sugar, sake, and salt.
