Crab apple jelly - NOT amateur radio

A few days ago I collected the crab apples from our single tree. 

Yesterday, I turned them into crab apple jelly as the photo shows. It is delicious on some meats.

I have no idea why they are called crab apples. They are tiny compared with more usual apples. I would guess 2cm diameter or less would be more typical.
