how to make a liner for drying onions
Onions are easy to dry, and being lightweight, they reconstitute easily. Peel and slice them in rings about 1/8 inch thick and put them in a dehydrator at about 140Â°F until they're nearly dry. To keep the pieces from browning, bring the temperature down to 130Â° F for the last hour or so and keep testing for dryness. If you don't own a dehydrator, try drying onions in your oven.
