Measurement notes
- Butter is often sold in sticks in the US, and one stick equals 113g (about half a cup).
- Soft butter should be packed firmly into the measuring cup to avoid air pockets that skew the weight.
- Cold butter is harder to measure accurately by volume — let it soften to room temperature first.
- European-style butter has a slightly higher fat content, which can make it marginally denser than US butter.
