Why measuring baking powder by cup goes wrong
Baking powder is a chemical leavener that combines baking soda with one or two acids. Double-acting powder reacts twice — once with liquid, once with heat. A cup weighs about 192 grams, but you'll never measure a cup; the working unit is the teaspoon.
Practical tips for working with baking powder
The baseline ratio is 1 teaspoon of baking powder per 1 cup of flour in a quick bread, biscuit, or muffin. Doubling the powder doesn't double the lift — it just leaves a metallic, soapy aftertaste. Baking powder loses potency over time; test an old can by dropping a teaspoon into hot water. If it doesn't fizz aggressively within seconds, it's tired.
Note from this ingredient's record: Rarely measured by the cup — listed for completeness. Use 1 teaspoon (4 g) per cup of flour as a baseline for biscuits and quick breads.
