A sweet-savory jam that you can—and should—make in the middle of winter. Canned, diced tomatoes star here, yielding a chunky texture that reminds me of a rustic chutney. If you want to skip the vinegar, well, don’t! Just like the salt, it helps balance the sweetness, making all the flavors pop.

In This Recipe
Set a large (roughly 12-inch) skillet over medium heat. Add the olive oil, then chopped onion. Season with a pinch of salt. Sauté, stirring occasionally, until soft, about 10 minutes.
Add the tomatoes, sugar, and vinegar. Stir. Adjust the heat as needed to keep at a steady simmer and cook, stirring often, until the syrup is thick and dragging a spoon along the pan leaves a distinct trail (about 25 minutes). Transfer to a heat-proof container and refrigerate to cool completely.
