Coriander
The leaves and seeds of the coriander plant are one of the most essential in Thai cooking. The root is also used, often pounded with garlic and other ingredients, to make a marinade. It is widely used as topping of many thai recipes such as Fried Fish with Tamarind Sauce [Pla Rad Prik], Thai Steamed Curried Fish [Haw Mok], etc.
