A dashi packet is a great alternative to making dashi (Japanese soup stock) from scratch. Use it like a tea bag to steep umami flavor into your broths and soups in just 5 minutes. It's so convenient and produces a much more flavorful stock than dashi powder.
To a medium saucepan, add 2 cups water and 1 dashi packet. DO NOT OPEN the dashi packet; use it similar to a tea bag to steep flavor into the stock.
Turn on the stove to medium heat and bring it to a boil. Once boiling, shake the bag a few times to release more flavor from the bag. Reduce the heat to medium low and simmer for 2–3 minutes.
Discard the packet. The dashi is ready to use.
To Store
You can keep the dashi in the refrigerator for up to 3–4 days. I don‘t recommend to freeze dashi made with dashi packet.
