Plums and tart apples cook down together with sugar, cinnamon, nutmeg and a touch of cloves into a smooth, spreadable fruit butter with a striking purple color. The plums bring tang and color, and the apples add body so the butter sets up thick without any added pectin.
This autumn recipe from the KitchenSimplicity archive is a good way to use up a few ripe plums. It makes a single jar, so there is no canning equipment involved; keep it in the fridge for toast, oatmeal and cheese boards, or tie a ribbon on the jar and bring it as a hostess gift.
Tips
- Store in the refrigerator for up to 3 weeks, or freeze in a freezer-safe container (leave 1/2 inch of headspace) for up to 6 months.
- This small batch is meant for the fridge or freezer, not for shelf storage. For water-bath canned fruit butter, follow a tested recipe and processing time from the USDA or the National Center for Home Food Preservation rather than adapting this one.
- Stir more often toward the end of cooking, when the thick butter is most likely to scorch and spatter.
- Double the batch in a wider pot if you have extra plums; the simmering time may run a little longer.
