Queen Anne's Pocket Melon, a photo by
gorydetails on Flickr.
Unusual heirloom melon, very small - softball sized or less - and very fragrant. In fact, it's meant to be used for its scent rather than for eating, which is rather a shame! [I did taste one and found it very bitter, odd since it gives off the scent of a perfectly ripe, sweet muskmelon...]
