The tradition of adding an egg to coffee is a practice that has been observed in various cultures around the world, particularly in parts of Europe and Asia. This unusual method of coffee preparation has sparked intense curiosity among coffee enthusiasts and skeptics alike. The question on everyone’s mind is: what does adding an egg to coffee actually do? In this article, we will delve into the world of coffee and eggs, exploring the history, benefits, and drawbacks of this unique coffee preparation technique.
History of Adding Eggs to Coffee
The practice of adding eggs to coffee has its roots in traditional Scandinavian and Vietnamese coffee cultures. In Norway and Sweden, it is common to add a raw egg to coffee grounds before brewing, a method known as “egg coffee.” This technique is believed to have originated in the late 19th century, when coffee was scarce and expensive. The addition of eggs was seen as a way to stretch the coffee and create a more filling beverage. In Vietnam, a similar technique called “cà phê trứng” involves whipping eggs with sweetened condensed milk and adding it to strong coffee. This rich and creamy coffee drink has become a popular tourist attraction in Vietnamese coffee shops.
Chemical Reactions and Flavor Profiles
So, what happens when you add an egg to coffee? The answer lies in the chemical reactions that occur between the egg and coffee compounds. Proteins in the egg white, such as ovotransferrin and ovomucoid, bind to polyphenols and other bitter compounds in the coffee, resulting in a smoother and less bitter flavor profile. The egg yolk, on the other hand, contributes to the richness and creaminess of the coffee, thanks to its high fat content. The combination of egg whites and yolks can also affect the.body of the coffee, making it more velvety and full-bodied.
Emulsification and Foam Formation
Another important aspect of adding eggs to coffee is the emulsification process. When eggs are whipped with coffee, they create a stable foam that can be used as a topping or mixed into the coffee. This foam is composed of tiny air bubbles surrounded by a film of egg and coffee compounds. The emulsification properties of eggs allow them to stabilize the foam, creating a long-lasting and creamy texture. This foam can be used to enhance the flavor and appearance of coffee drinks, making them more appealing to customers.

What is the purpose of adding an egg to coffee?
Adding an egg to coffee is a traditional practice in some Scandinavian countries, particularly in Norway and Sweden. The egg is cracked into the coffee grounds before brewing, and it serves several purposes. The egg helps to bind the coffee grounds together, allowing for a cleaner and more efficient brewing process. This results in a smoother and more full-bodied cup of coffee. The egg also helps to reduce the bitterness of the coffee, as the proteins in the egg bind to the acidic compounds in the coffee, resulting in a more balanced flavor.
The use of an egg in coffee is also believed to have originated as a way to clarify the coffee. The egg whites help to attract and bind to the impurities in the coffee, such as oil and sediment, resulting in a clearer and more transparent cup of coffee. This practice is particularly useful when using a French press or other immersion brewing method, as it helps to prevent the coffee grounds from becoming over-extracted and bitter. Overall, the addition of an egg to coffee is a unique and traditional practice that can result in a more enjoyable and flavorful cup of coffee.
How does the egg affect the flavor of the coffee?
The egg can have a significant impact on the flavor of the coffee, depending on the brewing method and the amount of egg used. When used in moderation, the egg can add a rich and creamy texture to the coffee, as well as a subtle sweetness. The egg can also help to balance out the acidity of the coffee, resulting in a smoother and more balanced flavor. However, if too much egg is used, it can result in a coffee that tastes overly rich and heavy, with a scrambled or cooked flavor.
The flavor of the coffee can also be affected by the type of egg used. For example, using a fresh and high-quality egg will result in a better flavor than using an older or lower-quality egg. Additionally, the brewing method used can also impact the flavor of the coffee. For example, using a French press will result in a more intense and rich flavor than using a drip brewer. Overall, the key to using an egg in coffee is to experiment and find the right balance of egg and coffee to achieve the desired flavor.
