Prune Conserve I

This prune conserve is a heritage preserving recipe from an era when cooks used every fruit available, including watermelon rind, to build complex, layered preserves. Six fruits combine here: prunes, apples, quinces, oranges, watermelon rind, and raisins. The result is a thick, jammy spread with a depth you won’t find in any single-fruit jam.

The base starts with prunes simmered until tender, pitted, then cooked down with chopped apples and quinces until soft enough to push through a sieve. That sieved puree gives you a smooth, velvety foundation. Diced watermelon rind and oranges go in next, adding texture and brightness to the dark fruit base.

Sugar goes in at three-quarters the volume of the fruit mixture, not a fixed amount, so taste as you go. The conserve simmers slowly with constant stirring until thick enough to mound on a spoon. Chopped nuts stirred in at the very end add crunch to every jar.

Chef Tips

• Use dried prunes (not fresh plums). They have concentrated sweetness and the right texture for a thick conserve.
• Quinces need longer cooking than apples. If you can, start the quinces a few minutes before adding the apples to get them to the same softness.
• Stir constantly once the sugar is added. This thick mixture scorches easily on the bottom and burned conserve is unsalvageable.
• To test thickness, drop a spoonful on a cold plate. If it holds its shape without spreading, it’s done.

Variations

• Skip the watermelon rind if it’s out of season and add an extra apple or two.
• Use walnuts or pecans for the nut addition, toasted beforehand for stronger flavor.
• Add a splash of brandy or port wine in the last 5 minutes for a boozy preserve that pairs beautifully with cheese boards.
