Solved Fruit identification please

Hi
I picked this fruit from underneath a tree in the local park. They are hard to the touch. There were lots that had fallen. Can anyone identify please and also are they edible?
Many thanks in advance.

 

Crab apples. More info, and recipes, here. I can definitely recommend the jelly!

 

Thanks very much for the reply. Crab Apples crossed my mind but they looked somehow different from the ones I've seen before. Thank you also for the link - much appreciated.

 

When in doubt cut one in half.
Cherries and plums are different.

1. Different crab apples.
2 and 3. Apple from the supermarket.

 

I think the term 'crab apple' might have evolved a bit since I was a kid. To me, crab apple used to simply refer to the horrible, tiny, usually a dull green/brown rock hard bitter apple as grows in the wild, probably as close as it gets to the original uncultivated wild apple.

Nowadays it seems to refer to a whole range of native species and cultivars that have been bred for their ornamental, rather than culinary value.

 

To make life still more complicated, some of the new ornamentals have also been bred to produce larger fruit, meant to be especially good for jelly making - e.g. Jelly King or Laura, which is the one I have here.
