Bicarbonate of soda

bicarbonate of soda

This commercially produced white powder is an alkaline substance used primarily as a raising agent. It reacts when mixed with acid foods such as lemonjuice, buttermilk and cream of tartar, or with boiling water, creating carbon dioxide or air bubbles.

Bicarbonate of Soda is often used in addition to baking powder to further boost the raising properties of cake mixes and so on. On its own it is an essential ingredient of recipes for Anzac biscuits, and the sweetmeat honeycomb, known in Scotland.
