This is an amazing recipe that's largely been forgotten and is very easy to make, but you won't find in a book. In the old days we used to cook a lot with lavender, but for some reason no one thinks of it as a herb any more. This is a real shame as it is an excellent flavouring if used in moderation. So if you fancy something truly different and very, very old school, then try out this recipe - you will not be disappointed!
1. The first thing you need to do is pick some plums and then wash them. Now the key thing to realise is that you need the plum stones in the mix you boil or the jam won't set. So the easiest thing to do is to just slice every plum along it's length and then bung it in the pot, don't bother to remove the stones (you can if you want, but make sure you bung them in the pot too).
7. Now your jam is ready, just fish out all the plum stones from the pot with a spoon - you're ready for bottling. Ladle the jam while still hot into your d jam jars filling each on to the top so there is only a little air space when the lid goes on. Now cut some round jam caps from some baking paper (grease proof paper) and place each one on the surface of the jam in the jam jar. Finally put the jam jar lid on and you're done - but do all this while the jam is still hot so everything stays serialized.
