I love making jam, but I only eat about two pints per year. In physics terms, this would result in a net positive flux of jam, except that it turns out that homemade jam makes a great hostess gift.
This year I made cherry, apple butter, and, just this weekend, blood orange marmalade. I'll be having the marmalade for dinner tonight, since it is Pancake Day. But there will still be plenty left in my larder. And if you'd like some, now you know what to do- just invite me over for dinner.
