The first infusion is fine at 6:30 and lets the next two infusions expand somewhat, keeping it nice, full, and honeyed. The flavors are similar and still drop consideraby after the first but they are so complex and satisfying! Fourth is a fight between caramel and konbu stock. Konbu wins by a dash of hijiki.
Fifth infusion: Stopping here because I need a dash of caffeine and I doubt rabbits like chipotle quinoa. Still some honey lazing about my gaiwan but even with lower temperatures this is broth by infusion four.
