Grape Jelly / Jam - how to thicken?

makinmoney, Apr 18, 3:48am
I had 2 supermarket shopping bags of grapes and decided to make one of them into jam / jelly.The problem i had is that i was unable to thicken it properly!I even tried with jam making sugar as i know it normally thickens faster than regular white sugar.Any suggestions on what else to do!At this stage i have ended up with a very nice grape syrup that is fantastic as a hot drink by simply adding hot water - but i would have preferred to have something i could spread on toast.

Pectin stock i posted recipe few weeks ago search in the search box.or pectin powder
you can even leave out sugar and make some sugar free

Try adding some citric or tartaric acid. I am having the same problems with the quince paste I made last night!

It is a real hassel, but reboil, adding packet of the jam setting mix.
follow the instructions tho.
