Most recipes I'm looking at calls for either 400g chopped tinned tomatoes or passata. I don't mind having tomatoes but I can't have too much of it otherwise it tastes horrible. Tried sugar and everything else but it still has that awful tang which my family and I really don't like. What can I replace instead? I don't mind using some tomatoes but what can I use to replace the rest of it? Would stock and corn flour be ok? I've really no idea lol. Thanks in advance
