This jam recipe takes the exact amount of juice that is extracted from the fruit to calculate the required sugar to create this beautiful jam.
I made this with just blackberries. It turned out well in spite of me being new to jam making and not quite getting the setting point right, went over a bit, so mine is very thick jam, but tastes great. I'm planning to try it as written with the elderberries next time. Really simple recipe to follow. - 30 Aug 2014 (Review from Allrecipes UK & Ireland)
This is the second year I have made this jam, love the simplicity and the fact most of the ingredients are free, I use a plate in the freezer to check for the setting point, doesn't take long, really recommend this recipe, I make them for Christmas pressies. - 22 Aug 2014 (Review from Allrecipes UK & Ireland)
Just made this for the first time, but I'll definately be making it again. Absolutely gorgeous! I didn't have the quantities in the recipe, so I just measured the juice and divided the weight of sugar accordingly. - 09 Sep 2014 (Review from Allrecipes UK & Ireland)
