Measuring Baking Soda Accurately

Why weight matters: 3/4 cup of baking soda can weigh anywhere from 147g to 207g depending on how you measure it. The USDA standard is 172.5g (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.

About 3/4 Cup as a Measurement

3/4 cup = 12 tablespoons = 180ml. This is one of the four standard cup measures (1/4, 1/3, 1/2, 3/4, 1). Common in cookie recipes where the flour amount sits between 1/2 and 1 full cup.

Three-quarter cup is a frequent flour amount in drop cookies, scones, and coffee cake toppings. At 180ml, it is exactly 3/4 of a standard US cup (240ml) and 12 tablespoons precisely.
