They are almost exclusively used in the form of a watery distillate called kewra water. Flowers have a sweet, perfumed odor that has a pleasant quality similar to rose flowers, but kewra is more fruity. The distillate (kewra water, pandanus flower water) is quite diluted; it can be used by the teaspoon, often even by the tablespoon. Most delightful, richest, and powerful of perfumes even when dried.
