Plumsapples

Or:
Damsapple Tree?

From Pomona's Store

We'll rather taste the bright Pomona's store,
No fruit shall 'scape
Our palates, from the damson to the grape.*

From An Ode to Master Anthony Stafford to hasten him in the Country by Thomas Randolph (1605 - 1634)

Damson and no Selilah

Lots of damsons* this year.

Here but a few I picked yesterday

to cook them four hours

and in between bake a cake

and finally get six glasses of damson butter.

* Before anyone asks: What are damsons?

Plums they are both. Actually the plum-family is quite big. For example, the mirabelle is also a member. :)

As for the difference:

The damson is the more juicy sister of the plum. :)
Plums are almost round and bigger; and their flesh tends to be reddish;
damsons are oval, and their flesh is yellow.
