Self-raising flour has more lifting power than a blend of plain flour and baking powder, so this is the best flour to use for heavy mixtures. Plain flours can raise a light mixture with the aid of baking pwder, especially if the recipe also contains eggs or egg whites which will help to aerate the mix.
If you want to make your own self-raising flour, sift 500 g (4 cups) plain flour with 4 level teaspoons baking powder.
