Ratios for making Dashi from Kombu and Katsuobushi Im trying to figure out the correct balance between kombu and katsuobushi when making dashi. I have read here that the perfect ratio between the glutamate in kombu and inosinate in the katsuobushi is an equal 1:1 ratio.

The problem is how can one attain these ratios or is it pretty much guess work as you never really know how much of each acid in the kombu or katsuobushi. How do you know how much has been extracted, how long to soak each for etc ?

Or does it really make a difference if there is more of one or the other ?

I would appreciate if anyone has any tips on the best way to make the Awase dashi and how to achieve a good synergistic balance that amplifies umami ?
Measure both with weight, start with a ratio you find to be tasty and produce varying kombu to katsuobushi ratios in equal steps, preferably 3 or 5 variations in small batches. Make sure to keep liquids, temperature etc. as much of a constant as you can.

Taste all, make notes and have others taste test them as well.
This process should be repeated each time the source of your katsuobushio or kombu changes.

Unless you live in Japan, consistency may be hit and miss.
