Prune vs. Plum: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on November 6, 2023
"Prune" is a dried plum, typically used as a snack or in cooking, while a "Plum" is a fresh, juicy fruit from the Prunus genus.

Key Differences

"Prune" refers to the dried version of certain types of plums, from the Prunus genus, and is often used in cooking and baking because of its sweet flavor and health benefits. "Plum," however, is the fresh fruit, known for its juicy texture, sweet taste, and deep color.
A "Prune" typically has a wrinkly texture, a result of the drying process which removes much of the water content found in the succulent "Plum." As a result, prunes are smaller and denser than their plum counterparts.
In terms of nutrition, "Prunes" are known for their high fiber content and are often recommended as a remedy for constipation. "Plums," being fresh fruits, contain more water and vitamin C, but less fiber compared to their dried counterparts, the prunes.
When talking about culinary uses, "Prunes" are often used in dishes like stewed prune, tagines, or even in stuffings because they hold their shape and offer a sweet flavor. "Plums," on the other hand, are more versatile in fresh culinary applications – they're eaten as is, or used in recipes for cakes, tarts, and jams.
From a botanical standpoint, "Prunes" and "Plums" come from the same family of fruit-bearing trees, but not all plum species are used to make prunes. Only specific varieties of "Plums" that are high in sugar, low in water, and free of bitterness are dried to become "Prunes."
