The spinach plant, whose famous leaves are harvested, is native to the Middle East and, more precisely, according to several historians its origin is to be found in Persia, from where it was then brought to Europe by the Arabs. There are different varieties of the spinach plant, among which the most famous are the following: the virofly, characterized by opaque leaves; the blackbird, whose leaves are folded; the matador, which is typical of the spring period; the rich one of Castelnuovo, with its typical thick leaves; and, finally, the winter giant, famous for its large leaves. Spinach can be cooked in many different ways, being an ingredient particularly chosen for preparing omelettes, soups, stuffed pasta and, again, many other delicious recipes.
