Plum jam recipe is easy to make, and uses only a few ingredients, one of which is fresh plums! Great on toast and pancakes!
What you need:
2 1/2 lbs plums, halved
1 1/4 cups water
4 1/2 cups granulated sugar or preserving sugar
pat of unsalted butter
What you do:
Put the plums in a nonreactive pan and add the water.
Bring to a boil, then simmer for about 25-30 minutes, stirring occasionally, until the plum skins are soft and the fruit is really tender. The liquid should be well reduced.
Stir in the sugar until dissolved. Add the butter and bring the jam to a boil. Boil rapidly for about 10-15 minutes until the setting point is reached.
Remove the pan from the heat, remove the pits and any scum from the surface with a slotted spoon.
Let stand for about 5 minutes. Stir the jam gently and remove from the heat.
Prepare and fill the jars leaving 1/4 inch-headspace and heat-process in a boiling water canner.
Let cool, label, and store in a cool, dark dry place.
