There’s a simple way to preserve summer’s ripe berries that requires no cooking, no jars, and best of all, no time. The only thing you need is a freezer large enough (or empty enough) to hold a single baking sheet.
Choose ripe berries without blemishes or bruises. Rinse the berries quickly if necessary, and then arrange them in a single layer, without touching, on a baking sheet. (A sheet of waxed paper or parchment will keep the baking sheet clean.) Set the berries in the freezer until they’re frozen solid—this will take anywhere from thirty minutes to two hours, depending on your freezer. Once the berries are hard, slide them off the sheet and into a zip-top freezer bag. The berries won’t stick together, and you can take out as many as you want at any given time. Use the berries as a dessert topping, in sauces, and in other recipes calling for fresh berries. Expect them to last up to a year in the freezer if kept tightly wrapped.
