**If you do not have a dehydrator, you can turn your oven to 175 F and place the macaroons on a baking sheet. Leave the door of the oven slightly ajar (Alessandra's post on dehydrating without a dehydrator
has a good tip for using a foil "snake") and leave them in the oven for 4-5 hours. Test them for firmness and give them another hour if they're very soft. Store as directed.
