I still had a bowlful of sloes standing in the kitchen, and since there is only so much sloe gin you can make (or drink), have looked around for another recipe using the hard little fruits.
Pamela Michael's Edible Wild Plants & Herbs, is the ideal book for this sort of thing as it goes into great detail about the many uses of various wild plants.
One concern with using sloes to make preserves is how to deal with the stones, having had several messy experiences picking plum stones out of stewed plums I wasn't keen to repeat this with the smaller sloe stones. The basis of this jam is a pulp of apples and sloes, which means you conveniently sieve out the troublesome stones.
