Buttermilk

Buttermilk is a cultured, acidic dairy product thicker than milk. Its acidity is vital for reacting with baking soda to create lift. Because of its viscosity, a significant amount clings to measuring cups. Weighing ensures you add the precise amount of acid needed for the chemical leavening reaction.

Weigh for pancakes, cakes, and marinades; acidity activates baking soda and tenderizes.

How this conversion works

Milliliters measure volume while grams measure weight. Because Buttermilk has a density of 1.03 g/mL, 10 mL weighs 10 g — not 10 g as it would for water. This converter uses the real density of Buttermilk so every measurement is accurate.

Measurement notes

Values are rounded to the nearest whole gram. Actual weight can vary slightly with compaction, temperature, and brand. For precision baking, a kitchen scale is always more reliable than volume measurements.

FAQ

Can I make a DIY substitute?
In a pinch, yes: add 1 tablespoon of lemon juice or vinegar to 1 cup of milk and let sit for 10 minutes. However, real cultured buttermilk is thicker and yields better flavor.
