Measuring buttermilk by cup and by weight
Buttermilk weighs about 245 g per cup, almost the same as milk. Its acidity is what matters in baking: it reacts with baking soda to give pancakes, biscuits and soda bread their lift. Thick, cultured buttermilk pours slowly and clings to the cup, so scrape it out or weigh it. Powdered buttermilk is a different measure and needs water added back.
