crab apples! (Wandsworth Common SW12)
Enough for making crab apple jelly.  If you haven't had it it's a delicate flavour, our family used to love it.  I just loved the jelly's colour:  a pinky apricot.  I have jars if you need them, but not lemons which I remember are needed too.  I have them in a bucket but they will need to go and be cooked very soon as they won't keep off the tree.
