Plum-Strawberry Jam
In my humble opinion, red plums make the best preserves, and certainly one of the easiest. Their skins give the jam a pleasant tartness and contain so much pectin that even inexperienced jam makers will be blushing like rosy plums with the pride of success. Tossing the fruit with sugar and letting it stand for a few hours intensifies the color of the strawberries so that the jam cooks up with a vivid crimson color.
