About measuring baking soda
Baking soda is a dense, fine powder, so a full cup weighs about 220 grams. In practice you almost never measure a cup of it: recipes call for teaspoons, and one teaspoon is about 4.6 grams. Precision matters more than for most ingredients, because too much baking soda leaves a soapy, metallic taste and can make a bake rise then collapse. When you scale a recipe up or down, weighing the leavening keeps the balance right.
Baking soda is powerful. Too much tastes soapy, so measure teaspoons carefully or weigh them.
