Green curry, with its mellow, creamy green color and rich coconut base, has both fresh and mature flavors. Like new growth on plants, it brings brightness, youthfulness, spring and rebirth to the meltdown of flavors created in the curry paste.
The green curry paste uses mainly the same standard ingredients as Thai spicy-red curry paste: lemongrass, coriander roots, kaffir lime zest, galangal, garlic, shallots, white peppercorns, coriander seeds, cumin seeds, salt and kapi.
Many recipes call for coriander root, garlic, and white peppercorns paste. While I have seen commercial preparations available, there is really no excuse not to use freshly made paste when needed. Successful cooking has a lot to do with the attention one gives to the flavor base and these three kings of Thai cooking should be taken very seriously.
I know it is easy to reach to the supermarket shelves and grab a pack of Thai curry paste. I hope that you will consider making your own and I think you should. Things often get lost in translation, and even worse if they are commercially pre-packed for five years of use. Thai cooking is based on freshness and if you are serious about Thai cooking, you will be amazed how with just a bit of an effort your food rises into new levels.
