Similar cold raw soups such as arjamolho in Portugal, porra antequerana and ajoblanco, are also popular in Andalusia, although not as widespread as gazpacho. Gazpacho and salmorejo are especially similar, since they are both tomato-based cold soups that are widely popular in Spain; the main difference between gazpacho and salmorejo is the culinary technique used since gazpacho is a soup whereas salmorejo is an emulsion. In addition, while both dishes share the main ingredients of tomato, olive oil, bread, and garlic, gazpacho can also be prepared with cucumber, peppers, and vinegar, whereas salmorejo cannot.
