Unlike other typical northern Thai food,klao soi uses coconut cream for the broth,chicken or beef instead of the ubiquitous pork,and wheat egg noodles rather than rice flour ones.The curry base involves roots like coriander,turmeric,and ginger and is simmered with coconut cream,stock,soy sauce and palm sugar,then poured over blanched noodles.Khao soi is served with pungent accompaniments like raw shallots,pickled mustard greens and chilli paste.
