Gazpachuelo is a soup originating in Málaga, Spain, and is a typical fisher's dish, consisting of mayonnaise, garlic, egg yolk, and olive oil. The egg white is added to thicken the mixture, along with cubed potatoes.[1][2]
Although it is consumed hot, gazpachuelo owes its name to the fact that it contains the four basic ingredients of gazpacho: bread, garlic, oil, and water. The bread is dipped into the soup. It is a typical dish of the lower classes because of the low cost of its basic ingredients. Variations of the soup include adding shellfish, peeled shrimp, or whitebait.
