The Greengage plum is deceptive in its looks, perhaps suggesting sour flavors with its unripe shades of mottled green and a taste similar to that of a tart granny smith apple. Rather, they have some of the highest sugar levels measurable, some reading almost 30 brix on the refractometer. They are a relatively small plum and depending upon variety can range from pale yellow-green to bright lime with rusty red speckling on their exterior. The amber colored inner flesh is dense and juicy with a tender yet firm texture, bursting with syrup-like juices. The Greengage's flavor is the perfect balance of candy-like sweetness and subtle acidity offering notes of honey, dried apricot, ripe mango and citrus marmalade.
