Mayonnaise is a thick sauce. It is an emulsion of vegetable oil and egg yolk, with either lemon juice or vinegar. It is often used as a condiment for food such as salads, sandwiches and french fries.


  • Mayonnaise is prepared using several methods, but on average it contains around 700 kilocalories (2,900 kJ) per 100 grams, or 94 kilocalories (Cal) per tablespoon. This makes mayonnaise a calorically dense food.
