Nam lamyai (longan drink)
Longan orchards cover the valleys of Chiang Mai and Lamphun, and every August the harvest is smoked and dried in big brick ovens so the fruit lasts all year. That dried lamyai is the base of nam lamyai, sold in plastic bags with a straw at Warorot Market, at roadside stalls on the way to Doi Suthep and in school canteens across the north, especially in the hot season from March to May. It tastes like toffee and smoked honey with a light floral note, and each glass comes with a few plump, chewy longans at the bottom to fish out. The common mistake is boiling the fruit too long with all the sugar at the start: the drink turns syrupy and the longans go mushy. Simmer the fruit first, sweeten at the end and taste before adding everything. It is ready when the liquid is clear amber-brown, the longans have swollen back to roughly their fresh size and the kitchen smells of caramel. It keeps 4 days in a closed jug in the fridge. Chef's tip: a tiny pinch of salt is the street-vendor trick that makes the sweetness taste rounder and brings out the smoky edge.
