Baking powder

Baking powder

This is made from bicarbonate of soda (baking soda) and a mild acid (usually cream of tartar). When moist and warm, these chemicals react and give off carbon dioxide, causing foods to rise.

Scones, cakes, puddings, biscuits and batters. The proportion of baking powder required will differ depending on the recipe.
