So nice really! Onion jam! Almost a contradiction in terms, as we usually associate sweet fruit with jam. But the result is also sweet when you cook onion jam, but with fine spicy notes and a little acidity from the vinegar. If you look very closely, jams are only made from citrus fruits and jams from other fruits. That would make our onion recipe more of a spread. In common parlance, however, jam has become established for the fine, sweet things in the jar and we are sticking with it.
In the English-speaking world, things look a little different. There you can find “onion jam” or “onion marmalade” as well as “onion chutney” and that is often served as a companion to burgers. We love that too, but are enthusiastic about the onion jam as an accompaniment to a fine cheese platter.
