In most supermarkets, you can buy pain flour or self raising flour but
if you are in a foreign place, self raising flour might not be readily
available.
The quick and easy way is to convert plain flour into self raising
flour by adding two teaspoons of baking powder into each cup of plain
flour.
Alternately, you can add one teaspoon of cream of tartar and half a
teaspoon of bicarbonate of soda to one cup of plain flour.
But there will be baking powder ?
