You will need:
Large handful damsons, stones removed 3 unripe pears Sugar 250g plain flour 125g cold butter A few spoons of cold water 1 beaten eggPut the damsons into a pan with a spoonful of sugar and a little water and heat them gently so they start to soften. While they are cooking, peel and dice the pears and then add them to the damsons. You want to keep them on a heat where the fruit makes gentle pfft pfft noises as it cooks, lid on, for about 20 minutes. You might need to add a little more water if the fruit starts to catch. After 20 minutes give the fruit a little squidge with a masher to puree it a little, keep a few lumps though. Taste it and add more sugar if you think it needs it. Remove from the heat and allow to cool, you don’t want much moisture left in the pan.
