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

Sodium bicarbonate. It needs an acid in the batter (buttermilk, yogurt, brown sugar, lemon) to make it rise, and it helps cookies brown and spread.

How to pick it

Keep a box just for baking, not the one in the fridge soaking up smells. To test it, drop a pinch into vinegar; it should fizz hard.

How to store it

Close it airtight and keep it dry in a cool cupboard: it soaks up moisture and smells.

Out of baking soda? What to use instead

  • Baking powder: 3 tsp baking powder for each 1 tsp baking soda. It rises, but bakes come out paler and puffier, cookies spread less, and the extra powder can taste a little bitter.
