Single-conversion pages for buttermilk
Working with buttermilk
Buttermilk sits in the liquids group, where the ingredient is denser than water, so a cup weighs more than 240 g and volume errors translate into large weight errors. Cultured buttermilk is thicker than milk but almost identical in weight per cup.
If you are converting a whole recipe rather than a single line, the Recipe to Metric converter matches every ingredient to its own density in one pass, and the Recipe Scaler resizes the batch first so you only convert once.
