Does it have yeast mixed in or something? or will general purpose flour do?
Self-rising flour is just flour with baking powder and salt added. You can make your own by adding 1 1/2 teaspoons of baking powder and 1/2 teaspoon of salt per one cup of flour.
It’s generally used for biscuits and soda bread, don’t use it to make “normal” yeast bread.
thanks!
Because it has lower gluten content. Bread flour in the UK will be labelled as such, or as “strong” flour.
