Mayonnaise is a creamy condiment made primarily from oil, egg yolks, and vinegar or lemon juice. It has a smooth texture and a rich flavor, making it a popular addition to sandwiches, salads, and dips. The process of making mayonnaise involves slowly whisking oil into the egg yolks, which helps to emulsify the mixture, creating a thick and stable sauce. This versatile spread can be used in various recipes, from classic tuna salad to deviled eggs. Many people also enjoy using mayonnaise as a base for other sauces, such as aioli or tartar sauce, enhancing the flavor of their favorite dishes.
