Why Weigh Buttermilk in Grams?
When a recipe calls for ½ cups of buttermilk, using a kitchen scale to measure exactly 120 grams will give you far more consistent results than volume measurement alone. This is because buttermilk can be packed, sifted, or scooped differently each time, leading to weight variations of up to 20%.
How to Measure Buttermilk by Weight
Place your mixing bowl on a digital kitchen scale and press "tare" to zero it out. Then add buttermilk until the scale reads 120g. This method is faster than measuring cups and eliminates the guesswork entirely.
