Been chopping and adding these to meatloaf and other dishes but can't always have fresh packaged on hand so which is better canned or dehydrated? Canned doesn't leave any choice of type but dehydrated does but is one better than the other. I remember Jac Pepin said buy the white mushrooms only better flavor than other verities. I know mushrooms are like spongers sucking up what ever they are cooked in but how do you rehydrate mushrooms properly? So far never had dehydrated anything work, celery has failed every time.
