Chiang Mai reveals its Chinese heritage with its devotion to pork products, most obvious in the northern Thai speciality of sâi òo·a (pork sausage). Good quality sâi òo·a should be zesty and spicy with discernible flavours of lemongrass, ginger and turmeric. One of the famous sausage makers is Mengrai Sai Ua, near the Holiday Inn on the east bank of the river.
