Marrons are fruits of trees growing in the southern parts of Europe: Italy, Spain and southern France. The plant is native to Asia Minor and Caucasus and was introduced in Europe by the ancient Greeks.
Marron fruit starts to ripen in September. A green shell covered with soft and long spines can hold up to four marrons.
Marrons are a rich source of B group vitamins and vitamin K, rarely available in plants.
They can be eaten raw, however, are most delicious when baked or cooked.
