Baking powder: what it is, how to pick and store it

Baking soda with its own acid mixed in, so it lifts a batter without an acid ingredient. Most is double-acting: it bubbles once when wet and again in the oven.

How to pick it

Check the date: old baking powder makes flat cakes. To test it, stir ½ teaspoon into a little hot water; it should fizz right away.

How to store it

Lid on, in a cool, dry cupboard. Moisture uses it up.

Out of baking powder? What to use instead

  • Baking soda + cream of tartar: ¼ tsp baking soda + ½ tsp cream of tartar for each 1 tsp baking powder. Rises the same if you don't let the batter sit.
  • Baking soda + buttermilk or yogurt: ¼ tsp baking soda for each 1 tsp baking powder, and swap ½ cup of the recipe's milk for buttermilk or thinned yogurt. Good rise with a light tang.
  • Self-rising flour: Use it for the flour and leave out the baking powder and salt. Each cup has about 1½ tsp baking powder and ¼ tsp salt built in, so it only fits recipes close to that ratio.
