Only made 4 bottles of 125 mls though.
However , I had the damsons ,and made some damson chutney with them. One red onion, finely chopped, a good pinch of salt, the same of mixed spice, pepper,and a shake of Turkish Chilli peppers., they are not too hot,and add a warmth to the mix. Let it all soften in the pan with the fruit, add cider vinegar to just cover the mixture, and enough sugar to taste. I never like an over sweet chutney, and as usual, the picture is somewhat lopsided. It has made 2 jars.
Will keep till Christmas easily.
