Be sure to tell us what you do with them.

imho, most mushrooms r better dried and reconstituted.
chants may be the exception, maybe some of the meatier 1s.
i use my dehydrator a.lot. i dont can or freeze, i dry. it intensifies the flavors. dried tomatoes r more like using paste than canned.
dried shrooms in mushroom gravy? heaven. soaked in stock in a stir fry? kicks it up a notch.

if this is more than u can use right away, get 1. i hear air fryers work for this.
esp if u can go get more, great way to keep.
