gazpacho became a very deeply rooted food for peasants and shepherds in the south of Spain. The basic gazpacho gave rise to many variants, some also called gazpacho, others not; some authors have tried to classify all these variations. Gazpachos may be classified by colour: the most usual red ones (which contain tomato), white ones (which contain no tomato, but include dried fruits), and green ones (which are white but contain some spices that make them green). These variants have their basic ingredients in common, garlic paste which works as an emulsifier, bread, olive oil, vinegar and salt. To the traditional ingredients red fruits such as strawberries, muskmelon, etc., may be added, making the gazpacho a bit sweeter. Gazpacho may be served as a starter, main dish, or tapa.
