Easy, peasy method of saving your mushroom harvest for later.
Take out your dehydrator and take out the trays, lay them out on a table.
With a sharp knife, cut EVERY puffball in half lengthwise (from top to bottom) Look inside to make sure they are indeed puffballs, marshmallow-like white interior with no baby gills or discoloration!
On a large cutting board, peel the thin "skin" off your halved puffballs with a potato peeler.
Slice your mushrooms thin with a sharp knife.
Spread out your slices on the food dehydrator trays, do not crowd.
Stack trays, not tightly and turn on machine. Check after each hour, they should be done in about 2 hours, maybe 3 depending on your machine.
Allow to cool completely, sliced should break easily. Store in glass jars until you wish to grind or use.
