How to make Jam with Knox

Question

I want to make Jam with Knox, but make it capable of being stored on a shelf, is this possible?

I read online that applejuice is a natural source of Pectin, and adding it will increase the shelf life.

Any thoughts or ideas?

I have 5 cups of pureed raspberries waiting to be canned, the cans, and a pot of hot water to give the mason jars a bath and seal.

TIA!

Answer 1

If I were you I wouldnt use knox.  Your making a jelly or jam?? Jam is tastier and you sure dont have to use knox in it...ewww

Answer 2

There is no need to use anything but sugar.  Just have equal amounts of white sugar and crushed berries.  Mix well and boil until thick.  Put in jars.

Answer 3

You don't actually have to jell your jam. You do have to add some sort of jell compound to jellies. I have never used either Knox unflavored gelatin or Jello to make jams. I have always used either Sure Jel or Certo.

It isn't the apple juice that has the pectin in it. It is the peels and core that contains the natural pectin. This is what Sure Jel and Certo have in them to "set" the jams and butters.

You might be able to find a recipe for your jam at recipezaar.com  just put in raspberry jam or raspberry preserves and see what you find. You can always click the ingredients tab also and put in raspberries and unflavored gelatin and see if that brings up anything.
