Leek is categorized as a bulb vegetable but botanically speaking, it is a member of the lily family.  Leek was cultivated in ancient times in its original form as elephant garlic.  It probably originated in the Near East.  

Leek is a frost resistant plant and that is why it is mostly planted in open fields. Depending on the growing season’s length, its consistency and taste may slightly change.  Its aromatic essential oils can be pungently sharp, especially in the winter leek, resulting in potential irritation that could lead to tears during its preparation. While it grows, leek is constantly being covered by new layers of earth, in order to avoid chlorophyll production and to keep the lower edible stems white in colour. When cleaning, leek must be cut and washed several times especially between its layers.
