I usually soak dried mushrooms in hot water for at least a half hour. Why not then put on some olive oil a little fresh thyme and a few bread crumbs sprinkled over them and bake them for 10 min or so in a 350 oven..yummy i would make whatever amount I was going to use in a short period of time if you want to make teaor make an infusion in any strenght desired

That sounds yummy, but I thought reishis were too "medicinal" to be eaten in the quantity you would eat regular mushrooms. Can you eat too much reishis?

I have never used reishi but from my understanding they can be very bitter...so I doubt cooking is going to be the way to go. I believe the dried bits are normally used to make a tea.
