Bought a bag of these. They are sliced and dehydrated. The instructions say to rehydrate them, place in boiling water for 15 minutes. Did that and they are "rubbery" when eaten. I have boiled and simmered for 2 hours. still "rubbery". Does anyone know if this is the character of this mushroom? Does anyone know about this mushroom? Guess I could chop them finely and try it that way. Was hoping to add these to some shreaded chicken. Thanks.
