Raw egg yolk, whipped and floated on hot coffee, sounds like a bodybuilder's mistake. Hanoi has ordered it daily since 1946.

Whipped yolk and condensed milk make a sabayon: fat, sugar, and air. Bitter, chocolatey robusta needs exactly those three things, which is why the combination lands as liquid tiramisu rather than coffee with egg in it.

The story

In 1946 Nguyen Van Giang was tending bar at Hanoi's Metropole hotel when fresh milk became scarce in wartime Vietnam. He whipped egg yolk with sugar and condensed milk as a stand-in for the milk foam in a cappuccino, and the substitute outlived the shortage.

Giang left the hotel to open Café Giảng, which his children still run, and the drink became a Hanoi institution copied across Vietnam. The classic serve is a small glass standing in a bowl of hot water to keep it warm while you work through the foam with a spoon.

Fair warning: The yolk is essentially raw, only warmed by the coffee, so this stands or falls on very fresh or pasteurized eggs, and a faint eggy aroma is part of the deal.
The recipe

Ingredients

  • 2 very fresh egg yolksor pasteurized yolks if raw egg worries you
  • 50 ml (3.5 tbsp) sweetened condensed milk
  • 25 g (4 tbsp) ground Vietnamese robusta coffeea dark French roast works too
  • 200 ml (about 1 cup) just-boiled waterfor brewing
  • 1 pinch cocoa powderoptional, for dusting

Method

  1. Brew the coffee strong: put the grounds in a phin filter over a small glass, wet them with a splash of hot water, wait 30 seconds, then fill the phin and let it drip 4 to 5 minutes; a moka pot or 60 ml of espresso per cup also works.
  2. While it drips, put the yolks and condensed milk in a small, deep bowl.
  3. Whisk hard for 5 to 10 minutes by hand, or about 3 with an electric whisk, until pale, roughly tripled in volume, and thick enough to fall in ribbons.
  4. Stir a tablespoon of the hot coffee into the foam to loosen and slightly warm it.
  5. Divide the rest of the coffee between two small heatproof glasses.
  6. Spoon the egg foam on top so it floats in a thick layer.
  7. Set each glass in a small bowl of hot water to keep the drink warm, the traditional Hanoi serving trick.
  8. Dust with cocoa if you like.
  9. Eat some of the foam with a spoon first, then sip so the coffee and cream come up together.
Shopping notes
Ground robusta such as Trung Nguyen is at Vietnamese and many Asian markets, and phin filters cost a few dollars online; chicory coffee like Café du Monde is a well-known stand-in. Use the freshest eggs you can find, or pasteurized yolks.
