Salsa golf

Salsa golf is a cold sauce of somewhat thick consistency, common in Argentina. It is made from mayonnaise with a smaller amount of tomato-based sauce such as ketchup, as well as seasonings including pimento, oregano, and cumin. According to legend, the sauce was invented by the physician Luis Federico Leloir in the mid-1920s at the golf club of the seaside resort Mar del Plata. Tired of eating shrimp and prawn with mayonnaise, he asked the waiter to bring various ingredients and experimented with different mixtures. The favourite was ketchup and mayonnaise. Leloir's companions named the result salsa golf, and its fame grew. Soon it spread to neighboring Uruguay while also being common in Chile. There are several recipes, but the sauce is always mostly mayonnaise with a tomato-based sauce like ketchup. Seasoning is added to give the sauce an Argentine flavor, such as pimento, oregano, and cumin. The mixture can also include Worcestershire sauce and mustard.
