I can never resist making jam when summer fruits are in season, but we don’t actually eat that much of it, so it accumulates in the larder till I give it away or cook with it. This recipe, based on one in Nadine Abensur’s Cranks Bible, used up most of a four-year-old jar of marmalade. American-style muffins, but unlike those, these are not over-sweet; the only sweetener is the marmalade plus a little maple syrup, and my home-made marmalade is true bitter-orange marmalade. The crunchy topping is interesting too.
You can use this as a basic muffin mix, replacing the marmalade with other not-too-sweet preserves, or fresh or frozen berries. Also, if you are like me and always have sourdough starter hanging around, try replacing part of the flour and buttermilk with it (see recipe for details).
