I am making Nigella's smoked sea salt chocolate tart and wonder if I can use cornstarch rather than cornflour as she uses in the recipe? Cannot find cornflour. Has anyone made this recipe?
Yes, they're the same thing.
According to someone with a Brittish husband in a recent thread, cornflour is the common term for cornstarch in England (assuming my memory is working today).
thanks so much Smaug for your reply !!! Appreciated !
