I have a friend who has had to go on a gluten free diet. She is my regular cat sitter and also she and her partner have been really helpful to me in all sorts of ways and I like to do things for them that they don't do, such as have them to home cooked meals and bake for them, which they love. But now I can't make them their favourite cakes from my well tested recipes. I have tried substituting spelt flour and it is horrible. Can I use corn or rice flour? What should I change? Does anyone have some good recipes for baking scones or cakes without using wheat flour?
