Measuring Tip
For the most accurate results, weigh mayonnaise on a kitchen scale. Volume measurements of thick spreads can vary by 5-10% depending on how firmly they are packed.
Understanding the Units
What is an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
