Drying Mushrooms and Onions

I love the rich, earth taste of mushrooms in a homemade soup or stew. Canned mushrooms are just not the same as fresh, and sometimes fresh mushrooms aren't the easiest thing to have around all the time. So, I'm dehydrating 3 containers' worth of Baby Bella mushrooms I got on sale last week, and since I have two extra trays begging to be filled (and I'm using the electricity anyway), I also chopped up 2 onions and put them on to dry! They are also great for use in soups and such!
