It is a powder that is often used in a certain amount such as miso soup and simmered dishes. I found a bottle at the 100-yen shop "Ceria" that saves me the trouble of weighing, so I tried it.
A product called "Easy Weighing Powder Dashi Bottle". The bottle has a special structure that is divided into two chambers by a partition plate, and a certain amount of powder soup stock is separated on one side. If you open the lid and tilt the bottle, about 1 teaspoon (about 4g (0.14oz)) will come out.
When I tried it with the dashi stock I always use, I succeeded in sharing about 5g (0.18oz). I felt that there was a lot of the original stick for one bag, so it may be convenient to transfer it to this.
On the other hand, a little over 1 teaspoon (4g (0.14oz)) of chicken soup base came out. You can add sesame seeds or furikake to prevent it from coming out too much.
So there seems to be some error depending on the contents, but if you are accustomed to cooking, there is no problem. If you really care, it may be good to know how much will come out when you transfer. The capacity of the bottle is 120 ml, and the price is of course 100 yen (excluding tax).
