Greengage

"The Greengage (Prunus domestica or the 'Reine Claude') is an edible drupaceous fruit, a cultivar of the plum. It was developed in France from a green-fruited wild plum (Ganerik) originally found in Asia Minor. It is identified by its small, oval shape, smooth-textured flesh, and ranging in colour from green to yellow, grown in temperate areas. They are known for their rich, confectionery flavour that causes them to be considered one of the finest dessert plums." Reference: Wikipeida.org
