Gazpacho is a cold Spanish tomato-based raw vegetable soup, originating in the southern region of Andalusia. Gazpacho is widely consumed throughout Spain, neighboring Portugal (where it is known as gaspacho) and parts of Latin America. Gazpacho is mostly consumed during the summer months, due to its cold temperature and acidic bite.
Gazpacho has ancient roots. There are a number of theories of its origin, including as an Arab soup of bread, olive oil, water and garlic that arrived in Spain with the Moors, or via the Romans with the addition of vinegar. Once in Spain it became a part of Andalusian cuisine, particularly Seville, using stale bread, garlic, olive oil, salt, and vinegar, similar to ajoblanco.
Gazpacho remained popular with field hands as a way to cool off during the summer and to use available ingredients such as fresh vegetables and stale bread.
There are many modern variations of gazpacho, often in different colors and omitting the tomatoes and bread in favor of avocados, cucumbers, parsley, watermelon, grapes, meat stock, seafood, and other ingredients. Gazpacho has become an almost generic term for chilled vegetable soup.
