Just wanted to say, when i was on cambridge diet i used vege gel but only for jellies not with the sachets. I mixed cold water, vegegel sachet and water flavouring with a drop of colouring and then boiled, poured into little containers and let it set. They were a godsend.
I did wonder about boiling it, but then I thought, it's different to microwaving and about the same as making it with hot water, which a lot of people do, so figured as it should be ok?
