How to Measure Mayonnaise Correctly
Mayonnaise should be measured by spooning it into the measuring cup and levelling it off. Unlike some ingredients, it shouldn't be packed down. For the most accurate measurements, especially in recipes where mayonnaise is a key ingredient, use a kitchen scale. Mayonnaise's thick consistency means it can be difficult to measure precisely by volume.
Understanding Mayonnaise Measurements
Mayonnaise is an emulsified sauce made from oil, egg yolks, and acid (usually vinegar or lemon juice). Recipes often say "mayo" — it's the same product. One US cup of mayonnaise weighs about 220 grams; half a cup is about 110 grams; one US tablespoon about 13.8 grams. Its creamy, dense texture means it measures differently than lighter ingredients, and accurate measurement matters when mayonnaise provides structure and moisture.
Common Uses in Baking & Cooking
Mayonnaise is used in sandwiches, salads, dips, and dressings. It's also used as a base for other sauces like aioli and remoulade. In baking, mayonnaise can be used as a substitute for eggs and oil in some recipes, adding moisture and richness. If you need a substitute, see our Mayonnaise substitution guide.
Storage and Handling Tips
Store mayonnaise in the refrigerator at or below 4°C. Once opened, it should be used within 2-3 months. Never leave mayonnaise at room temperature for more than 2 hours. If it develops an off smell or separates, discard it immediately.
