Just a couple of things to preserve some more of the summer fruit. I recently made Cherry Plum Jam. It's perfect for breakfast on your morning toast. Some sweet plums, some tart cherries, and you have a perfect breakfast spread.
Chop 3 of the plums into small cubes to give the jam texture and color.
Puree the cherries and the peeled plums in the blender. Cook the fruit with 3 cups of sugar and one packet of pectin until it reaches 220° on a candy thermometer.
