Since you are someone who clearly knows a lot about Japanese cooking, I wonder if you can recommend some decent quality inexpensive dashi powder?
This is one I'm considering.

That one's fine, I"ve used it. I currently have this jar of Ajinomoto in the fridge.
I like this one because it's a teaspoon to a cup, so when I need three tablespoons of dashi to make tamagoyaki, I mix a quarter teaspoon of dashi granules into a quarter cup of water, mix it, and throw out a tablespoon's worth.

Oh, I think I'll go with this jarred version then because I like the freedom to make a small quantity of dashi just as you describe. Thank you!
FWIW, I also keep actual kombu and katsuoboshi around. Some recipes, like mentsuyu, have you effectively making dashi using a hot mix of stuff like soy sauce, sake, and/or mirin in place of water.
FWIW, this is the kombu I like.
In Japan, people have arguments over whether Korean kombu is better or worse than Japanese kombu.

Kaneso, Yamahide, and Yamaki are pretty standard brands. The bag I have now is Yamaki.
Three ounces of katsuoboshi is enough to make three or four quarts of dashi, or three or four pints of mentsuyu.
