Look for plums that are free of blemishes, discoloration, and soft spots. You can ripen plums at home, so the important thing is to make sure you’re picking plums from a good batch – it’s okay if they’re still a little hard.
Rinse thoroughly under cool water removing any dirt by gently scrubbing with your finger.
Store fruits at room temperature, stem-end down. Ripe plums have dull skins and will last in the refrigerator for three to five days.
