Plum jam is a sweet spread made from ripe plums, sugar, and sometimes pectin, which helps it thicken. The process involves cooking the fruit and sugar together until it reaches a desired consistency. This delicious jam can be enjoyed on toast, in desserts, or as a filling for pastries. Plum jam is often made during the harvest season when plums are abundant. It can vary in flavor depending on the type of plum used, ranging from tart to sweet. Homemade versions allow for customization, such as adding spices like cinnamon or vanilla for extra flavor.
