Questions

What's the difference between hondashi powder and dashi stock?

Hondashi powder is instant dashi made from bonito flakes and kombu, while dashi stock is made fresh from the same ingredients. Hondashi is more convenient but dashi stock has more complex, authentic flavor.

Can I use fish sauce instead of hondashi powder?

Yes, but fish sauce is much stronger, so use sparingly. Mix 1/2 teaspoon fish sauce with 1 cup water for every teaspoon of hondashi powder needed.

Is hondashi powder vegetarian?

No, hondashi powder contains bonito flakes (fish), so it's not suitable for vegetarians. Use vegetable broth with soy sauce or miso paste instead.

How do I make dashi stock at home?

Soak kombu in water for 30 minutes, then heat to just below boiling. Add bonito flakes, let steep for 5 minutes, then strain. This makes traditional dashi stock that can replace hondashi powder.

Can I use chicken broth instead of hondashi powder?

Yes, chicken broth with soy sauce can work as a substitute, but it won't have the authentic Japanese flavor. Mix 1 cup chicken broth with 1 tablespoon soy sauce for every teaspoon of hondashi powder needed.
