The trick to properly storing fresh stone fruit is to make sure they don't get too cold before they fully ripen.
Exposing stone fruits to cold too early can cause them to take on a grainy texture.
Handle nectarines, peaches, apricots, and plums carefully as they spoil quickly if bruised. Store unwashed and stem-side down in a single-layer on the counter at room temperature until they are fully ripe (some suggest placing a dish towel or bubble wrap underneath to prevent bruising). Ripening can take up to three days. You will know when the fruit is fully ripe by the fragrant smell and soft flesh that should give a little when pressed gently.
Ripe stone fruit is best eaten right away. However, once ripe, stone fruit will keep for 3-5 days in a sealable bag or container in the fridge. Let return to room temperature before eating for best flavor.
