Kaeng som is probably the most well known southern dish within Thailand. Kaeng som is actually the name of a similar central Thai dish, so central Thais tend to refer to the southern version as kaeng lueang, or “yellow curry”, because of its color. This is not to be confused with the yellow curry that most foreigners are familiar with, which is a coconut-milk based curry of Indian origin called kaeng karii “curry curry” by Thais. Confused? Good, now we can begin.
