Your Dried Fruit Beats the Store's When You Make It With This

The same thermostatic dehydrator from the herb page earns its counter space all over again in fruit season - fruit runs hotter than herbs, 135F for most of a day, and the thermostat is again what separates chewy-perfect from case-hardened. If you bought it for the basil, September is when it really pays.

Run it in the garage in summer - a day of 135F warms a small kitchen.

Drying time follows thickness, so a hand-cut batch of thick-and-thin slices finishes as a mixed bag of moist (mould risk) and shattered (crumbs). A mandoline set to a quarter inch makes every apple ring identical, the whole tray finishes together, and a bushel gets sliced in an evening at the kitchen table.

Use the guard. Every mandoline story that starts without it ends the same way.

Apples and pears oxidize brown between the knife and the tray, and while brown rings taste fine they look like 1974. A quick dip in citric-acid water keeps them cream-coloured through the dry, brightens flavour a notch, and the same tub is the canning-acidity and cheese-making supply.

Lemon juice in water works; citric acid is just cheaper per batch.

Sauce season always makes more sauce than shelves, and the overflow poured thin on silicone sheets dries into fruit leather - the lunchbox item children trade upward for. The sheets also catch drippy things like tomatoes that would otherwise lacquer the trays permanently.

Pour thin at the middle, thicker at the edge - the edge dries first.

Dried fruit stored soft goes bad; stored open it goes hard. The same big jars from the ferment shelf hold a season of rings and leathers airtight where you can watch for the condensation that says 'not quite dry' - catch it in week one and the batch goes back for an hour instead of into the bin.

Shake the jar daily the first week - conditioning evens out the moisture.
