This worked very well for me - I had some jam which had not set, and this did the trick. FYI - this scales down well. I only had 4 half pints of jam to work with, so I just used the formula of 1/2 ounce each of sugar, lemon juice and pectin per half pint, and it set up beautifully. Thanks so much for posting this; it's so disappointing when jelly or jam does not set, and this does the trick to fix it!

I made a jam that had pretty expensive ingrediants and was upset when ti didn't set the way I wanted. Then remembered I'd saved this a long time ago and decided to try it. Awesome!!! It worked like a charm. Can't thank you enough for posting this. I do have a photo but my computer is giving me nightmares right now so will post later. This is a true life saver and I'll not forget it when (I hope never) the need arises.

tHANK YOU! I was making homemade applesauce and red current jelly at the same time. Hubby asked how long in the water bath, I said 20 minutes, thinking about the applesauce, the jelly should have been (5) minutes in the hot water bath. was syrup! Now thanks to this recipe I have nice, real nice red currant jelly.
