Baking Powder
This is for those times when you have baking soda (bicarbonate of soda) and tartaric acid (cream of tartar) in the pantry, but no baking powder. Make your own by combining 2:1 ratio of tartaric acid to baking soda. To make self-raising flour, add one teaspoon of your baking powder mixture per 110g of plain flour.
