Keep peaches at room temperature until ripe for best flavor and texture. Ripen peaches in a loosely closed paper bag. Add an apple or banana to speed ripening. Check daily until soft, then eat or refrigerate.
Store ripe peaches in the refrigerator in a plastic bag with holes to prevent moisture on the surface. Use within a few days.
Wash peaches just before using by gently rubbing under running water.
To keep them from browning, cut peaches just before serving or dip cut peaches in water with lemon juice (2 Tablespoons/quart).
To freeze cut peaches, first treat the slices to prevent browning (see above). Then freeze them on a baking sheet. Once frozen, transfer the slices to a freezer bag or container. Use within 12 months. Thaw in the refrigerator.
