hmmm its good for you natural fromage frais. I should of looked at it properly. Don't think this one is syn free? Will buy one tomorrow. my cake will have to wait.
What is the point of the quark in the recipe? Its just that fromage frais is a lot runnier than quark and if the quark is for 'substance' it wont work. Quark is a cheese. Fromage frais is a yoghurt.
