This morning I made three jars of jam from some of the fruit collected from my Victoria Plum Tree bought from Lidl. They are really tasty straight from the tree but lovely made into jam so that we can have the taste right through the winter too.
I usually cook large stoned fruit quite well in a little water and lemon juice then when the stones are floating on the top I put the whole lot through a seive and combine it with a little preserving sugar. There is pectin in the stones so no need to add more. Stir the fruit pulp and the sugar until the sugar is melted in then turn on the heat and bring the mixture to a boil. Keep stirring until the setting point is reached, not long with plums, and then pour into your jars using a funnel.
