Though the word salsa means any kind of sauce in Spanish, in English, it refers specifically to these Mexican table sauces, especially to the chunky tomato-and-chili-based pico de gallo, as well as to salsa verde.[2][3]
The use of salsa as a table dip was popularized by Mexican restaurants in the United States. In the 1980s, tomato-based Mexican-style salsas gained in popularity. In 1992, the dollar value of salsa sales in the United States exceeded those of tomato ketchup.[6]

Tomato-based salsas later found competition from salsas made with fruit, corn, or black beans. Since the 2000s sweet salsas combining fruits with peppers like habanero, Scotch bonnet and datil have grown in popularity and are served with frozen dessert, cheesecakes, and pound cakes.[7] In the United States, salsa is used in marinades, salad dressings, stews, and cooked sauces. In addition to accompanying various fish, poultry, and meat dishes, it is also used as a condiment for baked potatoes, pasta dishes, and pizza.[8]
Salsa is a common ingredient in Mexican cuisine, served as a condiment with tacos, stirred into soups and stews, or incorporated into tamale fillings. Salsa fresca is fresh salsa made with tomatoes and hot peppers. Salsa verde is made with cooked tomatillos and is served as a dip or sauce for chilaquiles, enchiladas, and other dishes. Chiltomate is a widely used base sauce made of tomatoes and chiles. The type of pepper used for chiltomate varies by region, with fresh green chiles being more common than habaneroinChiapas.[9] Tamales are often identified according to the type of salsa they are filled with, either salsa verde, salsa roja, salsa de rajas, or salsa de mole.[10]
Mexican salsas were traditionally produced using the mortar and pestle–like molcajete, although blenders are now used. Mexican salsas include:
The WHO says care should be taken in the preparation and storage of salsa and any other types of sauces, since many raw-served varieties can act as growth media for potentially dangerous bacteria, especially when unrefrigerated.[12]
In 2010, the CDC reported that 1 in 25 foodborne illnesses between 1998 and 2008 was traced back to restaurant sauces (carelessly prepared or stored).[14]
A 2010 paper on salsa food hygiene described refrigeration as "the key" to safe sauces. This study also found that fresh lime juice and fresh garlic (but not powdered garlic) would prevent the growth of Salmonella.[15]
