Hi there, I am having a difficult time with baking sponge cakes. I can bake a cake using self raising flour from Tesco and it works fine, but if I use any other SR flour they tend to sink or over rise. With the Tesco flour I can use 4 eggs about 200 grams and 300 grams of flour but with the other flour it has to all be equal. I hope this hasn't been asked before, I feel like a Tesco flour addict

the generally accept ratio for self rising flour is
1.25 teaspoons of baking powder to 1 cup of plain flour

a teaspoon in volume if 5 ml; a cup of flour 130-135 grams

of course, it's difficult to know how much "other" flours are using, so if the Tesco brand works, stick with it.
