- Buttercream
- Sauces and pan cooking
Butter has a stable reference weight, but recipes can specify cold, softened, melted or clarified butter. The weight stays close, while the best measuring method and the ingredient's behavior in a recipe can change.
The converter does not assume that every cup weighs 237 or 250 grams. It uses the documented value for the exact ingredient and state selected.
If a product label or recipe publisher supplies a different gram weight for one cup, follow that recipe-specific value for the closest match to the original testing.
