Measurement notes
- Vegetable oil is a category, not one substance; this record specifically uses refined soybean oil.
- Measure it as a liquid at eye level and avoid retaining oil on another container during transfer.
- Canola, corn, sunflower, and blended oils are close but not guaranteed to match exactly.
Common mistakes
- Not measuring vegetable oil (soybean) the recommended way — poured into a liquid measuring cup at room temperature — is one of the most common sources of error.
- Assuming 1 cup of vegetable oil (soybean) equals 240g like water — it is actually 218g per US cup.
- Measuring cold, hard butter by volume instead of letting it soften first.
