Method
- Make the palm sugar syrup: combine palm sugar, water and pandan leaves in a small pot. Simmer 8 minutes until the sugar dissolves and the syrup thickens slightly. Cool. Discard pandan.
- Warm the coconut cream gently with salt — never boil. Cool to room temperature.
- Prepare the toppings: have the jackfruit, palm seeds, beans, sticky rice, tapioca pearls and grass jelly in separate bowls.
- To serve: in each tall glass, layer 2 tbsp of red beans at the bottom. Add a generous spoonful of jackfruit. Add 1 tbsp each of palm seeds, sticky rice, tapioca pearls and grass jelly.
- Add a generous amount of crushed ice — to the brim. Drizzle 2 tbsp palm sugar syrup over the ice. Pour cool coconut cream to fill three-quarters.
- Serve immediately with a long spoon. The drink is meant to be stirred together by the diner — the various textures against the sweet coconut and ice is the architecture. Eaten as an afternoon dessert in Vientiane's hot season.

Cultural Note
Nam vahn — 'sweet water' — is the Lao street dessert, the Lao counterpart to Cambodian cha houy teuk and Vietnamese che. The dish has dozens of variations across Laos; vendors in Vientiane and Pakse have their preferred toppings. The pile of mixed components is the architecture; eating with a spoon and stirring is the eating method. Nam vahn stalls operate from afternoon through evening in Lao cities, serving customers seeking respite from the tropical heat.
