Ok, I'm googling as we speak but getting overwhelmed with too many varying results and there used to be a tradition of LPSG recipe-swapping. I've got about a pint of home-made cranberry sauce (300g/12oz cranberries, 200g/8oz sugar, a bit of water and a glass of good rioja red wine) and a pint of double cream left over from New Year's Eve. What proportion of sauce/cream should I use? Should I add milk/egg yolks? I don't have an icecream machine but I'm prepared to fork/whisk every now and again as it freezes. Or should I make a cheesecake?
