Measuring Baking Soda Accurately

Why weight matters: 1/4 cup of baking soda can weigh anywhere from 49g to 69g depending on how you measure it. The USDA standard is 57.5g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.

About baking soda density: Baking soda (sodium bicarbonate) is 3-4x more powerful than baking powder. 1 teaspoon = 4.6g. Requires an acid (buttermilk, vinegar, lemon juice) to activate. Substituting requires adjusting recipe acid content.
