Pandan is the flavour of this cake. They are leaves, found in most asian stores. However, living in the UK, it isn't as easy as you think when looking for pandan leaves.
But nothing will stop me from making this fluffy cake, so I moulded around what I had which happens to be pandan flavouring.
Although I'm not 100% with the artificial "greeness" of this cake, the texture satisfies me enough :)
