kgb Posted September 15, 2019 Share Posted September 15, 2019 Yesterday the wife and I put up a batch of ginger pear jam, or tried to, and it hasn't really set. We've had other episodes in the past where jam failed to set and chalked it up as ice cream topping. Today we made some caramel spiced pear jam and it's still warm from the final bath, wondering if there is a way to set that first batch. I've searched a bit and found this page http://pickyourown.org/how_to_fix_runny_jam.htm that seems to offer a solution or two, what have you done to get jam to set? Link to post Share on other sites
SelbyLowndes Posted September 15, 2019 Share Posted September 15, 2019 Add pectin, maybe sure-jell and mix. Reheat it of course to mix...SelbyLowndes Link to post Share on other sites
RJR Posted September 15, 2019 Share Posted September 15, 2019 Make sure you get it to a rolling boil after adding correct amount of pectin. Also don’t make it all in one batch. A couple qts at a time works better. Link to post Share on other sites
kgb Posted September 16, 2019 Author Share Posted September 16, 2019 The recipes call for one packet of Sure-Jell and yield is usually 6 half-pints plus part of a 7th. Slight differences in cooking instruction and ingredients in the 3 recipes we've been using, all however say the same for cooking with medium-high heat and one minute after rolling boil you take it off the heat to skim/cool for 5 mins before putting into jars then jars into the canning pot. One recipe is very specific about that one minute and not more than a couple seconds additional, but there are a few ticks of the clock where "rolling" is in question and I figure when the lava starts spitting out of the cauldron when you halt stirring for a second, that's a roll and I start the clock. Not just the first sign of bubbles. The linked article describes the 3 elements required to set jam, plus the heat requirement. Says riper fruit has less natural pectin, we were processing some pretty soft pears and I would think if the combination depends on natural pectin from the fruit we might have been a bit short in that batch. It also describes going to a "hard boil" beyond the roller, indicating higher heat than our other instructions. Finally, it shows a lesser time in the water bath, based on our altitude, the first time I've seen that and maybe the extra time in hot water was undoing some part of the process. We'll find out. Appreciate any and all practical experiences in the fix process. Link to post Share on other sites
kgb Posted September 16, 2019 Author Share Posted September 16, 2019 Also, how long does this stuff last? In digging out the supplies I ran across a few jars from 2015 that we'd set in a box and buried in a cabinet underneath the new jars. Does it have a particular odor when it's "turned"?

browndrake Posted September 16, 2019 Share Posted September 16, 2019 Jam/jelly is pretty high in sugar and lasts quite a while. I think officially, it is good for two years. I just opened, and am using, a case of pomegranate jelly that we put up in 2012. Looks/tastes like new. If I have a batch fail to set,I will often add more pectin or some more lemon juice and cook a bit longer. Link to post Share on other sites
kgb Posted September 23, 2019 Author Share Posted September 23, 2019 The pickyourown solution worked, seemed a bit more pectin than should have been necessary but a success it was. The light jam is the crystallized ginger variety we treated, the darker version is "spiced caramel" (allspice, nutmeg, cinnamon and substitutes brown sugar for some of the white) and set up fine the first shot. It boiled a little longer, maybe 15-20 seconds and that might have made the difference. We have a solution for future failures at least. Link to post Share on other sites
Spin Posted September 27, 2019 Share Posted September 27, 2019 This minor disaster happened to me when making a large batch of Elderberry Jelly. I tried twice to add more pectin and a bit more sugar. Still too thin. However it wound up being the best pancake/waffle/French toast syrup I ever tasted and I continue to make it every year. There is bag full of ripe elderberries in the freezer as I write this, waiting to be rinsed off, stemmed and cooked and then put up. Link to post Share on other sites
kgb Posted September 27, 2019 Author Share Posted September 27, 2019 How big was the large batch? Most suggestions I've encountered limit batches to 4 cups of fruit or a little more, one claim being it's too hard to get a uniform distribution of the pectin, acids and sugars throughout.
