From 1700, in Sicily, citrus growing became so profitable that it prompted farmers not only to spread it but also to enrich it with new types such as "blood orange" or pigmented.
The first treatises were published at the beginning of the last century.
In October 1929, a study was published which describes the history of the origin of the cultivation of the tarocco orange, which dates back to the late 1800s.
In March 1933 an article was published in "l'Italia Agricola" describing the varieties called "Sanguinello", "Tarocco" and "Moro".
In 1935 a monograph was published in the "Annals" of the "Royal Experimental Station of Acireale fruit growing and citrus growing ”where it is specified that the cradle of this variety is the town of Pedagaggi, a fraction of Carlentini in the province of Syracuse.
