Bay Leaves

Bay Leaf

Bay leaf, (Laurus Nobilis), refers to the aromatic leaves of the bay laurel tree, scientifically known as Laurus nobilis. These leaves are commonly used as a culinary herb to impart flavor and aroma to various dishes. Bay leaves are native to the Mediterranean region and have been used in cooking for thousands of years.

History of Bay Leaf

Bay leaves have a long and noble history. The ancient Romans and Greeks used to make crowns out of true bay leaves to crown great and accomplished people. These great people usually included kings, war heroes and Olympians. The term ‘baccalaureate’ originates from this giving of bay leaf crowns to signify success, as does the term “poet laureate”.

Cooking with Bay Leaves

Bay leaf not only has medicinal properties but is also used in cooking. The freshly dried bay leaves have a warm aroma, which is infused into cooking. The leaf is crushed before being used. The leaf is used for flavoring stews, dishes that need a long time to cook and soups. However, it is removed from the dish before serving.

The aroma of the leaves is much more noticeable than the taste. The fragrance of the dried leaf is herbal and floral.

Bay Leaf Habitat & Types

Although a native of Asia Minor, the Laurus nobilis tree can be found in the Mediterranean owing to its partiality for warm climates. This is generally referred to as Mediterranean Bay Leaf. The Bay leaf tree is an evergreen tree that grows up to a height of 12m. The growth rate is very slow. A mature bay leaf is approximately 5cm wide and 10 cm in length.
