What is ‘Umami’ flavor in dashi?
Umami flavor is known as the fifth basic taste which is savory, meaty, or rich. This distinctive type of flavor is considered to be a flavor booster in a dish, making things taste a lot more satisfying.
The umami flavor occurs from glutamic acid, an amino acid naturally found in many foods such as seaweed, mushrooms, or even cheese.

How to make dashi packets
1. Grind. Place bonito, shiitake mushrooms, and niboshi in a food processor or blender. Process until fine. Transfer to a bowl.
2. Add konbu. Using a kitchen knife, cut the kombu into tiny pieces (about ½ inch) and add to the bowl. Add salt to the bowl as well and mix.


3. Pack. Split the dashi into 10 tea bags or dashi bags. They will each have 8g of dashi, or roughly 1 heaping tablespoonful each.
4. Simmer. To make dashi broth, place one packet into 2 cups of water and slowly bring to a boil. Once it reaches the boiling temperature, turn down to low heat immediately and let simmer for 5 minutes. Take the dashi packet out of the water, squeezing the liquid out to get the maximum flavor.

Tips
- If bonito flakes do not fit in your blender at once, grind in batches. The volume comes down in seconds, so put some amount, blitz, add more, blitz, and repeat.
- You can also store the dashi in an airtight container and transfer to a tea bag as you go.
- Make sure the tea bags are large enough so the dashi has enough space to spread and release flavor into the broth. I use 10cm x 10.5cm bags.
FAQ
Tear the bag open and mix into fried rice, or stir fries. If you would like to make it into furikake rice topping, add some soy sauce, mirin, and a touch of sugar. Cook off the moisture in a small pan.
When kombu is ground finely, it releases bitterness and sliminess into the broth. It is best not to ground kombu, roughly cut them into smaller pieces and mix into the rest of the ingredients.
These dashi packets can be stored in the fridge for up to 1 month, covered tightly. You may also freeze them for up to 3 months, in a freezer bag.
