Exposing stone fruits to cold too early can cause them to take on a grainy texture.
Store nectarines, peaches, apricots, and plums on the counter at room temperature until they are fully ripe. This can take up to 3 days. Once ripe, place them in a sealeable bag or container in the fridge for up to 5 days.
You will know when a peach or a nectarine is fully ripe by the fragrant smell and soft flesh that should give a little when pressed gently.
