Pandan Essence is delightful scent that's used in flavoring many desserts throughout Southeast Asia especially Thailand (known as "Bai Toey").
Pandan (screwpine pandanus) is a type of plant that grows in tropical areas of Asia. Pandan leaves have a sweet, unique flavor that is commonly used in Southeast-Asian countries to enhance both desserts and savory dishes. The leaves are long and bright green, and when pounded or ground, they lend a sweet taste and aroma to many Thai desserts, some drinks, cakes, and pastries. One bottle of this will last a long time as it only needs a few drops.
