Not used these before.
Normally I make jelly from the cubes, and I add a tin of fruit, and use the juice from the tino make up the liquid to a pint.
I made this using a sugar free sachet and a tin of mandarins about 2 and a half hours ago and it isn;t showing the slightest sign of setting.
Am beginning to think i hve done something wrong an dit is never going to set.
Should I wait it out or serve a raspberry and mandarin drink ?
