The damson is actually one of many varieties of plum. The fruit is harvested in late summer to early fall.
This plum variety has a slightly acidic taste and a stronger flavor, making this pudding a very fun recipe to try. Of course, if you can't find damson plums, choose another variety. This is a tasty pudding no matter what plum you use!
