Hi this is great. But when I went to my Asian supplier they suggested using flakes. I have 3g in 5 packs. But I have a recipe that calls for a 1/4 cup of dashi granules in 375 mils of water (after soaking dried shitake). Can you tell me the conversion? Do I use 1 pack or 2? Any assistance will help (I'm trying to impress my wife who is just coming home from "lady" surgery.......pls help a "batchelor"
