An update: brandy and plum jam do not mix
Just can't taste any difference, waste of decent brandy imho
Leave it for a while ........
Oh it'll get left for a while. We have LOADS of plum jam. Fair decent it is too
Just took several cycles of cook, pour into jars ailing when it doesn't set, empty out, boil again
BUT
It has given Mrs K great fun and in my book what puts a smile on Mrs K's face is always good
