Sorry to post in AIBU but need quite urgent responses so I make it to Waitrose in time! I made nigellas chilli jam. Well, tried to. Made it once years ago and it worked beautifully so I thought I would do it again. But because I was being silly and in a rush, I used granulated, not jam, sugar. As Soon as I realised, I took it off the boil as It won't set.
I'd say I've made about 4-5 mugs. Google tells me I can add some pectin, but how much should I add?
