Bay leaves are the aromatic leaves of the bay laurel, an aromatic evergreen shrub native to the Mediterranean. Fresh leaves have minimal flavor, but whole dried leaves are commonly used in soups, sauces and stews in Italian, North American and Asian dishes. The dried leaves impart a mild herbaceous taste to a dish but they must be removed prior to serving, as they retain sharp edges that can damage the digestive tract. Bay leaves are also valued for their use as a natural insect repellent in kitchens and pantries.
