When we think of homemade preserves and spreads, we often picture the sweet fruits of summer, like berries and cherries. But they can be so much more, especially in fall. Late-ripening tomatoes and peppers and fall-harvested onions, apples, and plums are just a few of my favorite ingredients in jams, jellies, and other spreads.
You might be thinking, “Do you really put vegetables in jam?” Yes, I do! These savory spreads are thick with flavor but not as sweet as spring and summer spreads. Because many of the vegetables are low in acid, they need to be treated differently from fruit preserves. Some have a fair amount of sugar, some are heavy on vinegar or another acidic ingredient, and many use a combination of both to create a sweet and savory blend that’s safe to process in a boiling water bath.
