The plum is a stone fruit that grows on trees in the Prunus genus. Depending on the variety, a plum may be green, red, purple, or yellow, and all have smooth, edible skin and sweet flesh surrounding a pit. The fruit is grown throughout the world, though China, Romania, Serbia, and the United States lead commercial cultivation. It's a global ingredient, found in cuisines from Eastern Europe to Asia, as well as North and South America. Plum can be eaten raw as a fresh, sweet-tasting snack. In the kitchen, the fruit is most often used in baked goods or boiled to create jams and sauces for both sweet and savory dishes.
