My friend Summer emailed me recently to talk about the possibilities of making jam with glucose. I've never made jam before, though hope to one day, so really didn't know what I was talking about. Summer has, however, and we had quite a discussion about the properties of sugar and about pectin in fruit and decided it was well worth a try. So she went away and did the hard work, while I just watched my letterbox for a few days until some was delivered.
