Food That Makes Harvest Last
There always comes a time when I can't pay anyone to take another zucchini.
That’s about the time every summer that I start dehydrating my extra produce. Although the frontrunners of food preservation have always been canning, freezing, and pickling, dehydration offers its own benefit: versatility. Whether you buy a dehydrator or use your kitchen oven, dehydrating transforms the bounty of the garden into powders; chips; and prepped, presliced, ready-to-cook vegetables.
Harnessing low, slow heat to coax out moisture morphs vegetables into ultracrisp versions of themselves—ready to munch on or store for another day. Dehydrators come in two common styles: stackable tray units and box. Using temperatures from 105°F to 145°F, both circulate dry heat to slowly draw out the moisture of various produce. Circular, stackable tray units are the old-school workhorses. They have a top-mounted fan that pushes hot air downward and can be easily expanded by adding extra trays. Box-style dehydrators include silicone-lined trays that slide into the unit much like oven racks. The fan unit located on the back circulates heat evenly among the trays for efficient and precise drying.
Herbs can be dehydrated, too. Basil, parsley, cilantro, and other tender herbs dry in a flash and can be crushed or ground into fragrant powders. It’s hard to go back to purchased versions of dried crushed herbs once you’ve made your own. Onions and garlic are also great candidates for dehydrating. Both make fresher versions of store-bought powders, but when left sliced, they can be whipped into dishes, such as garden-fresh Ratatouille Frittata, long after summer is gone.
Some vegetables need a little preparation before dehydrating to produce the best results. Because they are water-rich, eggplant, zucchini, and tomatoes take longer to dehydrate, so slice them thin to reduce drying time. To prevent oxidation, these veggies should first be blanched or given a dip in water laced with lemon juice to remove the enzyme that causes browning.
I believe the timeless tradition of dehydrating brings a new element to the joy of gardening. When you bite into a dish made with a dried tomato harvested at its peak flavor, the magic of the garden lingers.
