One of the tastiest and most popular Thai dishes; Tom Kha Kai simply requires fresh lemongrass; dried galangal (a plant in ginger family with refreshing milder odor), mushrooms and coconut milk. Although technically it is called a soup, it is most often served with rice and eaten like a curry, spooned over rice and then eaten. It is Thailand's answer to chicken soup, and like most Thai dishes, enhances a common soup well beyond the typical.
Warning!: Despite of their shape and rhizome family, this key galangal in Tom Kha Kai is irreplaceable with Ginger.
