Kem xôi (Hanoi coconut ice cream on sticky rice)
In the Old Quarter of Hanoi, kem xôi shops on Hàng Bài and around Hoàn Kiếm lake serve it from late morning to late at night through the hot season: a bed of warm, salty sticky rice, a scoop of coconut ice cream melting into it, then crisp toasted coconut and crushed peanuts. The contrast of warm and cold, chewy and creamy, is the whole point. This is a no-churn ice cream with no eggs and no custard. Sweetened condensed milk is the base: its sugar and milk solids lower the freezing point and keep crystals tiny, while whipped cream folded through traps air so it freezes soft without stirring, and coconut milk gives the flavour. Make the ice cream the day before and steam the rice just before serving. Chef's tip: whip the cream only to soft peaks; the common mistake is overwhipping it until stiff, which turns grainy and buttery once it freezes.
