The mirabelle plum is a small round fruit with a yellow color and a sweet taste. The tree is medium sized but it produces many fruit. When to be eaten fresh, harvesting is done by hand, while mechanical harvesting methods are used for fruit that will be dried. The fruit mature more or less at the same time, which explains why a large number of mirabelles are made into marmalade.
Mirabelles are rich in vitamins A and C, contributing to bone and immune system health. They also contain niacin, which maintains a healthy metabolism and nervous system. Mirabelles are an important source of fiber, and thus help bowel function.
