 The sword-shaped leaves own a pleasant slightly vanilla-nutty odor, fresh or dried. They are used in many cuisines of Southeast Asia as a condiment. The fresh leaves (indonesian Daun Pandan, thai bai tooey, ใบ เตย) are either cooked with the food or the food is wrapped in leaves and steamed within or fried; in all cases the leaves serve only for adding flavor and are not consumed. Pandan leaves are frequently used in the preparation of less high-quality rice varieties, to improve their taste. [[https://de.wikipedia.org/wiki/Pandanus_amaryllifolius]]
-"The leaves are also used as a flavoring for desserts such as pandan cake and sweet beverages." [[https://en.wikipedia.org/wiki/Pandanus_amaryllifolius]]

-The scent of pandanus leaves develops on wilting, the fresh plant is virtually odorless. However, the flavor (nutty-hay-like) evaporates pretty quickly after complete drying. [[http://gernot-katzers-spice-pages.com/germ/Pand_ama.html]]

+"Pandanus amaryllifolius, an herb, is cultivated in home gardens in coastal regions of India. The leaves are added to ordinary rice while cooking to impart basmati rice aroma. The plant bears the same aroma principle 2-acetyl-1-pyrroline (2AP) that has been reported in Basmati and other scented rice. Quantitatively the 2AP  contents are highest in this plant among the plant kingdom. Therefore, it has good scope for commercial cultivation." \\

+"... 2AP, hexenal and nonanal were found to be major compounds present in elevated amounts than scented rice. 2AP (popcorn-like, pleasant odour) accounted for 8.52% of total volatiles besides hexanal (green tomato, grassy odour, 6.63%), 2-hexenal (green, apple, grassy odour, 21.87%), nonanal (floral, soapy, citrus-like odour, 10.50%), 2,6-nonadienal (cucumber-like odour, 3.11%), 3-methyl-2(5H)-furanone (caramel, sweet honey odour, 3.12%) and phytol (5.28%) being major components. Adding the raw leaves of P. amaryllifolius in ordinary rice to impart basmati aroma has remained as an old practise in south-east Asian countries." \\
