Curry powder is the heart of this recipe, obviously. Different brands of curry powder have different strength of curry and slightly different taste. As it's difficult to always have my Malaysian brand of curry powder fully stocked in my kitchen, so I started to use the local brand which is Carmencita, which is in the reasonable price range compared to other brands here. I have to use more amount of Carmencita's curry powder because it is quite mild and the end result is delicious :)
