It’s okay if they touch a bit on the trays, as the pieces will shrink away from each other as they dry, but don’t heap them on in layers.
If you prepped and blanched more than you have the trays for at one time, store them in a sealed container or bag in the fridge for up to 3 days, and dry as dehydrator tray space becomes available.
Let the dehydrated product cool completely to room temperature before packing it into storage containers.
Watch the sealed containers for the first few days for any sign of condensation. If condensation occurs, dehydrate a bit more.
Label jar with name of product and date. Store away from heat and direct light.
Use in soups, stews, casseroles, quiches, rice dishes, etc.
