Wikipedia: Mayonnaise
Mayonnaise (UK: /ˌmeɪəˈneɪz/; US: /ˈmeɪəneɪz, ˈmæneɪz/), colloquially referred to as “mayo” (/ˈmeɪoʊ/), is a thick, cold, and creamy sauce commonly used on sandwiches, hamburgers, composed salads, and French fries. It also forms the base for various other sauces, such as tartar sauce, fry sauce, remoulade, salsa golf, ranch dressing, and rouille.
