Salsa golf is a creamy Argentinian sauce which usually consists of a mix of mayonnaise and ketchup. It can be prepared with homemade or store-bought ingredients, and can also include mustard, lemon, and a variety of fresh and dry spices and herbs.

According to the famous legend, the sauce was invented by the Nobel-awarded scientist Luis Federico Leloir, who (in search of a more imaginative condiment) came up with the idea of mixing mayonnaise and ketchup. Today, salsa golf is one of the Argentinian national sauces, while store-bought versions are available in supermarkets and grocery stores throughout the country.
