Vietnamese Egg Coffee, also known as "Cà Phê Trứng," is a delightful and unique coffee indulgence that has its roots in Vietnam's coffee culture. The drink is said to have been invented in the 1940s, during a time when milk was scarce, leading a creative bartender to use egg yolks as a substitute. This inventive concoction quickly gained popularity and became an integral part of the Vietnamese coffee tradition.
The cultural significance of Vietnamese Egg Coffee lies not only in its rich history but also in its role as a symbol of hospitality and togetherness. It is often served during family gatherings and celebrations, and as a gesture of warm hospitality to guests. The blending of bitter Robusta coffee with the creamy, sweetened egg layer creates a smooth and velvety texture that has captivated coffee enthusiasts both in Vietnam and across the globe. Today, this beloved beverage continues to be an integral part of Vietnamese coffee culture, preserving a delightful taste of tradition.
Understanding The Art And Science Behind Vietnamese Egg Coffee
The art of preparing Vietnamese Egg Coffee revolves around the careful selection of traditional ingredients and mastering the intricate preparation methods. The traditional recipe typically includes strong Vietnamese Robusta coffee, which is brewed using a drip filter, ensuring a robust and bold flavour. The egg mixture is made by whisking egg yolks with sweetened condensed milk until frothy, creating a luscious and creamy topping. The hot coffee is then poured over the egg mixture, allowing the two layers to beautifully merge.
While the classic recipe remains timeless, modern variations have emerged to cater to diverse tastes. Some variations include using egg whites to create a lighter foam or adding a touch of flavour with coconut milk or chocolate. Creative twists, like incorporating flavoured syrups or toppings like crushed nuts, have also gained popularity. These adaptations showcase the versatility of Vietnamese Egg Coffee while preserving the essence of its original charm.
The science behind Vietnamese Egg Coffee lies in the process of egg emulsification. When egg yolks are whisked with sweetened condensed milk, the proteins in the egg yolks form a stable emulsion with the fats in the milk. This emulsification creates a creamy and velvety texture, transforming the egg mixture into a frothy layer when hot coffee is poured over it. The emulsification prevents the separation of the egg and milk components, resulting in a smooth and consistent texture throughout the drink.
In contrast to regular coffee and other espresso-based drinks, Vietnamese Egg Coffee stands out due to its luxurious and decadent mouthfeel. The combination of the robust Robusta coffee with the silky egg layer creates a unique sensory experience. The drink is neither purely coffee nor a typical milk-based beverage, making it distinct in flavour, texture, and appearance. This innovative approach to coffee preparation highlights the artistry and scientific understanding that elevate Vietnamese Egg Coffee to a one-of-a-kind indulgence.

Recipe For Vietnamese Egg Coffee

Ingredients:
2 tablespoons coarsely ground Vietnamese Robusta coffee (or any strong coffee of your choice)
3 tablespoons sweetened condensed milk
2 large eggs
1 teaspoon vanilla extract (optional)
Hot water
Ice (optional)
Equipment:
Vietnamese drip filter (phin) or any coffee maker
Mixing bowl
Whisk or electric hand mixer
Coffee cup or glass
Instructions:
Prepare the Vietnamese drip filter by taking the bottom part of the drip filter and adding the sweetened condensed milk to it.
Place the ground coffee in the filter chamber of the drip filter.
Use the press to gently compact the coffee grounds.
Set the filter over a coffee cup or glass.
Separate the egg yolks from the whites, placing the yolks in a mixing bowl.
Add the vanilla extract (if using) to the egg yolks.
Whisk the egg yolks vigorously until they become frothy and pale in colour.
In a saucepan, heat about an inch of water until it simmers gently.
Place the mixing bowl with the frothy egg yolks over the saucepan, creating a double boiler.
Continue whisking the egg yolks over a gentle heat until they thicken slightly. Be careful not to cook them fully; the goal is a creamy, custard-like texture.
Once the coffee finishes brewing into the cup or glass, stir the sweetened condensed milk at the bottom to combine it with the brewed coffee.
Carefully pour the thickened egg yolk mixture over the coffee, creating a distinct and luscious layer.
Vietnamese Egg Coffee can be enjoyed both hot and cold. If serving cold, add ice to the glass before pouring the coffee and egg mixture. Use a spoon to mix the layers and savour the unique flavour and texture of this delightful beverage.
Note: Be cautious when using raw eggs in the recipe, especially if you are pregnant, elderly, or have a compromised immune system. To reduce the risk of foodborne illness, consider using pasteurized eggs or heating the egg mixture to a safe temperature while whisking over the double boiler.
