Pandan is widely used in a variety of foodstuffs. The screw-pine leaves gives a unique flavor and aroma which enhances the flavor of our favorite sweets and refreshments.
Pandan extract and powder forms are now readily available from almost every grocery store and baking supply.
If you have access to pandan leaves and really want the real one which is far way better than the expensive leading brands, there are two ways of making pandan extract: 1. Boiling it with water, the traditional way, 2. The use of blender.
Do it however you like at your convenience. But I guess boiling it releases more flavor and aroma.
