This recipe is from Liana Krissoff's book "Canning For A New Generation". You can use it instead of powdered pectin in jelly and jam recipes (I wouldn't try using it in Pepper Jelly, though. I'm not sure if it would work in that). I add one cup of this to any recipe which produces 3 pints or less of product (jam, jelly). If the recipe produces more than 3 pints, add an extra 1/2 cup of pectin stock for every 24 ounces of extra product. If you use this pectin, you will need to use the cold plate test to check the set of your jelly or jam. The instructions for this are included below.
