Method
- Stone the damsons. Be prepared, this is a horrible job as it takes ages and stains your fingers! I hope you'll agree it's worth it.
- Use a food processor to grate the onions, garlic and apples (take the cores out first).
- Put everything into a large preserving pan and bring to the boil. Simmer for several hours, stirring it occasionally so it doesn't stick to the bottom of the pan.
- When it's greatly reduced, it's ready to put into hot sterilised jars.
The flavours will mature when stored for a few months, if you can wait that long!
