Why Weighing Buttermilk Beats Measuring Cups
Measuring dry or compactable ingredients like Buttermilk by volume (cups or spoons) is notoriously inaccurate. Depending on how you pack the ingredient, or the ambient humidity in your kitchen, a cup of Buttermilk can vary in weight by up to 30%.
Weighing your ingredients in grams gets rid of all that guesswork. When you use exact weights, your recipes will turn out exactly the same way every time, no matter how packed your flour is or how humid your kitchen feels.
This converter uses real density numbers for Buttermilk. When you swap cups for grams, you're getting actual weight conversions that real bakers use, not just a generic guess.
A simple kitchen scale takes the guesswork out of baking and cooking.
Frequently Asked Questions
There are about 242 grams in 1 standard US cup of Buttermilk. However, this weight depends on the cup system you are using: for example, a metric cup is larger (250 ml) and weighs about 256 grams, while a US Customary cup is about 236.6 ml.
The weight of a cup of Buttermilk can change depending on how tightly it’s packed, humidity, and even how long it’s been sitting in the pantry. For dry ingredients like flour or sugar, scooping directly with the cup packs it down, adding up to 25% more ingredient than a recipe calls for. Using a kitchen scale is the only way to get the exact amount every time.
If you don't have a kitchen scale, use the "spoon and level" method: gently fluff the Buttermilk in its container with a spoon, spoon it into your measuring cup until it overflows, and sweep the excess off the top with the flat back of a knife. Never shake the cup or pack it down, or you'll end up with too much.
