The Greengage is a strange fruit, I really don't know why I bother to keep the tree in front of the house. The trunk is rotting, and clearing up all the mess from the dropping fruit is an annual nuisance.
Either they have worms inside them, or they are so sweet that they make your hair curl.
The only way to eat them is to catch them semi-ripe, open them in half (to check for lodgers), and consume them directly underneath the tree. I probably eat a maximum of 20 each year. Like that they are delicious, but hardly worth all the hassle of clearing-up the mess they produce.
I always look forward to their arrival, then wish I hadn't. Bok eats a few.
