For sponges I use McDougall's Supreme Sponge self raising, I find this flour gives my cakes a very light texture. I also tend to get McDougall's for plain flour too. As well as those I always have Gluten free flour in my cupboard, both plain and self raising, Doves Farm I think for my granddaughter's dietary requirements. I've made her birthday cakes, cup cakes and Yorkshire puddings, which she loves. I use the gluten free plain flour to thicken gravy for roasts when she is with us, and it works well in a roux for a cheese sauce with pasta, which she often asks for.
