Measuring baking soda by cup and by weight
Baking soda is roughly 6 g per teaspoon, or about 288 g per cup. It is about three to four times stronger than baking powder, and it needs an acid in the recipe, such as buttermilk, yogurt, brown sugar or cocoa, to do its job. Too much leaves a soapy flavor and a yellowish crumb. Measure it with care and break up any lumps.
