Stone Fruit
Stone fruits, including the likes of peaches, apricots, nectarines, and plums – all ripen best at room temperature. This means that it is best to avoid putting them in the refrigerator. This holds unless you have no plans to eat them right away. Either way, these fruits should ripen at room temperature first for the best eating experience.
Stone fruits are unique, and when left to ripen in a fridge – they get what we call “chill damage.” Here’s some science for you, when fruit gets left to ripen below 50 degrees Fahrenheit, the ripening process stops altogether, resulting in mostly flavorless fruit.
