Cà phê trứngEgg coffee
Hanoi's old-quarter cafés, up narrow stairs and in tiny back rooms, serve cà phê trứng in a small cup set in a bowl of hot water so it stays warm while you spoon through the custardy foam into bitter coffee below. The topping is egg yolk whisked with condensed milk until pale and thick, a trick that began when fresh milk was scarce in the 1940s. Because the yolk is not cooked, use pasteurised eggs for pregnant women, young children, older people or anyone with a weakened immune system. Chef's tip: whisk longer than you think; under-beaten yolk tastes eggy and sinks straight into the coffee instead of sitting on top.
