Greengage Tart

In the 18th century, Sir William Gage planted some French plum trees at Hengrave Hall, near Bury St. Edmunds, without knowing exactly what type of fruit to expect. The plums turned out to be green and became known as the green Gage's plum, which eventually became shortened to greengage. They are sweet, oval and yellowy-green with a good flavour and are in season late August and early September.
