Friend J, N, and I went to the Japan Society to learn the secrets of making dashi.N asked the presenter where to buy high quality bonito for making dashi. Turns out that the secret supplier is Amazon.They gave us sample of three types of dashi: kelp, bonito, and mushroom. Only the bonito one tasted like anything to me. Some salt would have been nice.The Japan Society seemed pretty nice. They offer Japanese classes there too!
