Vietnamese Egg Coffee (Ca Phe Trung) combines coffee with a rich, creamy egg-based foam resulting in a thick and decadent concoction that is almost similar to a dessert.
In a narrow container with high sides, add egg yolks, condensed milk, sugar and vanilla extract. Use a milk frother or a hand mixer and beat until it has thickened and doubled in volume (Note 2).
In a cup, add ice cubes. Then pour the milk, and the espresso shot.
Then pour the foam on top and sprinkle some cocoa powder.
Notes
1. coffee - you can replace the espresso with instant coffee, simply dilute 2 tsp of instant coffee into 2½ tbsp of hot water. You don't have to make a latte for this recipe, you can use the coffee of your choice such as a lungo or your regular everyday coffee.2. hand mixer - you can also use a frother but note that some frothers aren’t powerful enough to thicken the egg yolks. If this is the case with yours, use a hand mixer.3. hot coffee - you can also make this recipe with hot coffee. Add hot milk instead of cold milk and ignore the ice cubes.
