What is a "greengage"?

The greengage is a small, round fruit with a smooth green skin and juicy, sweet flesh. It is a type of plum belonging to the species Prunus domestica, known for its distinctive flavor that balances sweetness with a hint of tartness. Greengages are often enjoyed fresh as a snack or used in culinary applications such as desserts, jams, and preserves. They are prized for their delicate texture and unique taste. Originating in Europe, greengages are now cultivated in various regions around the world and are typically available during the summer months.
