Homemade Baking Powder mamabake

by Emma Chow

Baking powder turns up in most of the biscuit, cake and quick-bread recipes we have in our arsenal.

As a combination of a bicarbonate and acid, baking powder leavens and increases the volume of baked treats through the chemical reaction of an acid and base which releases carbon dioxide gas into your dough or batter. Think of it as a less explosive version of what happens when you add vinegar to bicarb for cleaning purposes.

Baking powder is generally made of sodium bicarbonate, otherwise known as baking soda, and cream of tartar. Cream of tartar is the acid component and is a by-product of wine-making; cream of tartar forms from the tartaric acid of the grapes as they ferment. Cream of tartar is often used when making meringue, as a small amount of acid can help stablise the egg whites and achieve a meringue that is crisper on the outside and marshmallow soft on the inside.

You’ll probably notice that some recipes only use baking soda and not baking powder. These are generally recipes that already have an acid component in them, such as vinegar, lemon juice, buttermilk and non-alkalised cocoa.

Baking powder also generally contains corn starch or some starch. This is used to absorb moisture and allow baking powder to last longer by prevent the acid-base reaction from occurring before it hits your batter.

With just a few pantry staples, you can make your own baking powder when the urge to bake strikes!
