Baking powder
Pronounce it: bay-king pow-dah
A raising agent used in baking that combines mild acid (usually cream of tartar) with mild alkali (such as bicarbonate of soda). When mixed with liquid the powder generates carbon-dioxide forming bubbles that cause a mixture to expand.
Availibility
Can be bought in a packet or tin or buy a self-raising flour that already contains it.
Prepare it
Make it yourself by combining half a teaspoon of tartar and quarter of a teaspoon of bicarbonate of soda. This will make the equivalent of 1 teaspoon of baking powder.
Store it
In a cool, dry place.
