How to make a buttermilk substitute
No buttermilk on hand? Make a quick stand-in: stir 1 tablespoon of lemon juice or white vinegar into 1 cup of regular milk, then let it rest 5–10 minutes until it thickens and curdles slightly. It won't be as rich as cultured buttermilk but works in almost any baking recipe. A cup of buttermilk weighs about 245 g — a touch heavier than milk because of its body. Always shake the carton and measure to the line, since buttermilk separates as it sits.
