Damson Okanagan plum varieties have a very strong tart taste and are not good for fresh eating, but they are the most common plum types used for making plum jam, jellies, syrups, and different plum preserves. They can also be stewed and used in pies, tarts, and ice creams.
The tartness of Damson plums makes them especially suitable for savory dishes such as lamb, pork, or other meat dishes such as a delicate Moroccon beef stew.
Damson's ripen fast and quickly become over-ripe, so they need to be stored in a cooler for only a day or two, between 0° - 2° C (32° - 36° F). The plum types are generally available in the Okanagan Valley beginning in early to mid August."
