Glutafin gluten free flour mixes can be used as a substitute for self raising flour when baking cakes, biscuits and pastry. This is because Glutafin flour mixes are a blend of gluten free flours, specially developed to mimic mainstream flour. It is best to check depending on which gluten free flour you use, as gluten free flours which are just a single ingredient e.g. rice flour will not behave in the same way as self-raising flour.
