तेज पता / Bay Leaf come from several plants, such as:
Bay laurel (Laurus nobilis, Lauraceae). Fresh or dried bay leaves are used in cooking for their distinctive flavour and fragrance. The leaves should be removed from the cooked food before eating (see Safety section below). The leaves are often used to flavour soups, stews, braises and pâtés in many countries. The fresh leaves are very mild and do not develop their full flavour until several weeks after picking and drying.
California bay leaf – the leaf of the California bay tree (Umbellularia californica, Lauraceae), also known as California laurel, Oregon myrtle, and pepperwood, is similar to the Mediterranean bay laurel, but has a stronger flavour.
Indian bay leaf or malabathrum (Cinnamomum tamala, Lauraceae) differs in that bay laurel leaves are shorter and light to medium green in colour, with one large vein down the length of the leaf, while tejpat (Cinnamonum tamala) leaves are about twice as long and wider, usually olive green in colour, and with three veins down the length of the leaf and is culinarily quite different, having a fragrance and taste similar to cinnamon (cassia) bark, but milder.
Indonesian bay leaf or Indonesian laurel (salam leaf, Syzygium polyanthum, Myrtaceae) is not commonly found outside Indonesia; this herb is applied to meat and, less often, to vegetables.
West Indian bay leaf, the leaf of the West Indian bay tree (Pimenta racemosa, Myrtaceae), used culinarily (especially in Caribbean cuisine) and to produce the cologne called bay rum.
Mexican bay leaf (Litsea glaucescens, Lauraceae).
Chemical constituents: The leaves contain about 1.3% essential oils (ol. lauri folii), consisting of 45% eucalyptol, 12% other terpenes, 8-12% terpinyl acetate, 3–4% sesquiterpenes, 3% methyleugenol, and other α- and β-pinenes, phellandrene, linalool, geraniol, terpineol, and contain lauric acid also.
Taste and aroma: If eaten whole, bay leaves (Laurus nobilis) are pungent and have a sharp, bitter taste. As with many spices and flavourings, the fragrance of the bay leaf is more noticeable than its taste. When dried, the fragrance is herbal, slightly floral, and somewhat similar to oregano and thyme. Myrcene, which is a component of many essential oils used in perfumery, can be extracted from the bay leaf.
Uses: Bay leaves can also be crushed or ground before cooking. Crushed bay leaves impart more fragrance than whole leaves, but are more difficult to remove, and thus they are often used in a muslin bag or tea infuser. Ground bay laurel may be substituted for whole leaves, and does not need to be removed, but it is much stronger. Bay leaves are also used in the making of jerk chicken in the Caribbean Islands. The bay leaves are soaked and placed on the cool side of the grill. Pimento sticks are placed on top of the leaves and the chicken is placed on top and smoked. The leaves are also added whole to soups, stews, and other Caribbean dishes.
