Pandan has specific flavour and fragrant aroma that can not be replaced with any other ingredients. Pandanus leaves commonly grow in South East Asia but we can find easily the Pandan extract everywhere in Asian store, usually in a small bottle.
In Indonesia, Pandan use for many kind of dishes and dessert.
The fresh Pandan leaves look like these.
In this recipe I used Pandan extract. If using Pandan juice, use as replacement of water in the dough making.
