How to choose the best:
Plum

AKA: DAMSON

Touch

A good plum is plump and firm, but not too hard. If it's hard, it's underripe, while mushy, means overripe.

See

Look for glossy, unbroken skin, and a consistent color, with a nice blush over top.

Keep an eye out for any bruises, major discolorations, or shriveled spots.

Smell

Give a good sniff: ripe plums have a nice floral smell. Too sweet or fermented might mean the plum is past its prime.

How to store

Once your plum is fully ripened, store it in the fridge for longest life.

If the plum needs to ripen it a bit more, you can leave it out for a day or two until its good and ready.
