"kombu, mirin, & bonito...where can you find them/what are good substitutes?" Kombu is dried seaweed (laver) used to make dashi soup stock/broth. Mirin is sweetened rice wine. Bonito refers to katsuobushi, a dried fish, usually in shavings. There are no acceptable substitutes for these, & any pan-Asian grocer should stock them. Most mirin available in the US is not real mirin. 'Fake' mirin is called 'aji-mirin'. Use as last resort only. NB: Soup Base Recipe doesn't give size of kombu pieces?
what are the following ingredients: kombu, mirin, and bonito and where can you find them or what are good substitutes?
