Yam tua plu (wing bean salad)
Wing beans grow on fences in back gardens all over central Thailand, and their frilly, four-edged slices make one of the most loved yam on a family table, eaten alongside a curry and rice at dinner. The beans are blanched for seconds so they stay crunchy and grassy, then coated in coconut cream sharpened with lime and nam prik pao, with peanuts and crisp shallots on top. The usual restaurant version adds poached prawns or minced pork and seasons with fish sauce; this one uses tamari, so it is vegan. Look for wing beans in Asian grocers; fine green beans work too. Chef's tip: the common mistake is overcooking the beans; blanch them for 30 seconds only and plunge into iced water, or they turn olive-grey and limp.
