|---|---|---|

Why Does 1 Cup of Buttermilk Vary?
The weight of 1 cup depends on how you measure. USDA standard (spooned) = 245g.
Standard pour
Pour liquid into measuring cup at eye level. For liquids, density is consistent regardless of technique.
ConsistentAbout Buttermilk Density
Buttermilk is similar in density to skim milk. 1 cup = 245g. The acidity (pH 4.5) activates baking soda and tenderizes gluten. No buttermilk? Mix 1 cup milk + 1 tablespoon white vinegar/lemon juice, wait 5 minutes.
Pro tip: For consistent baking results, use a kitchen scale. Weight measurements eliminate the variability of cup measurement entirely. USDA values shown are based on the spooned & leveled method.
