Bay Leaves

Introduction

Bay leaves are aromatic leaves commonly used in cooking and traditional medicine. Derived from various plants, the most well-known variety is the Laurus nobilis, or true bay leaf, which has been a staple in Mediterranean, Indian, and Middle Eastern cuisines for centuries. Other varieties, such as Indian bay leaf (Tej Patta) and West Indian bay leaf, offer unique flavors and applications. Bay leaves add depth to soups, curries, and stews, and are also used in herbal teas, baked goods, and medicinal remedies.
