Cocktails have come a long way from their humble beginnings, with mixologists around the world experimenting with unique ingredients to create innovative and intriguing drinks. One such ingredient that has gained popularity in recent years is the humble egg white. Yes, you read that right – egg whites have become a staple in many modern cocktails, adding a velvety texture, stability, and a touch of elegance to the drink. But what exactly does an egg white add to a cocktail, and why has it become a favorite among bartenders and drinkers alike?
The Science Behind the Foam
To understand the role of egg whites in cocktails, let’s dive into the science behind the foam. Egg whites, also known as albumen, are a clear liquid that makes up approximately 90% of an egg’s composition. The primary protein found in egg whites is ovotransferrin, which is responsible for the formation of a stable foam.
When an egg white is whipped, the ovotransferrin molecules unfold and reorganize, creating a network of air pockets that trap air and create a light, airy texture. This process is known as denaturation, and it’s the same principle that applies to whipping cream or making meringues.
In cocktails, the egg white is typically shaken with other ingredients, such as spirits, citrus, and sugar, to create a silky, velvety texture. The protein molecules in the egg white react with the acid in the citrus and the sugar to create a stable foam that can be poured over the drink, creating an Instagram-worthy presentation.
The History of Egg Whites in Cocktails
The use of egg whites in cocktails dates back to the late 19th century, when bartenders would use them as a clarifying agent to remove impurities from drinks. However, it wasn’t until the early 20th century that egg whites became a popular ingredient in their own right.
The classic cocktail that popularized the use of egg whites is the Pisco Sour, a Peruvian cocktail made with Pisco brandy, lime juice, sugar, and an egg white. The drink was created by Victor Morris, an American bartender who opened a bar in Lima, Peru, in the 1920s. Morris experimented with different ingredients and techniques to create a unique drink that would appeal to the local palate.
The Pisco Sour quickly gained popularity, not only in Peru but also around the world, and it’s still a staple on cocktail menus today. The use of egg whites in cocktails has since become a standard technique, with bartenders experimenting with different flavor combinations and presentation styles.
The Benefits of Egg Whites in Cocktails
So, what does an egg white add to a cocktail? Here are some of the key benefits:
Texture and Mouthfeel
Egg whites add a silky, velvety texture to cocktails, which can enhance the drinking experience. The protein molecules in the egg white create a smooth, creamy sensation in the mouth, making the drink feel more luxurious and indulgent.
Stability and Foam
Egg whites create a stable foam that can be poured over the drink, adding a touch of elegance and sophistication to the presentation. The foam can also be flavored with ingredients like citrus zest or herbs to add an extra layer of complexity to the drink.
Clarification and Filtration
Egg whites can be used as a clarifying agent to remove impurities from drinks, making them clearer and more visually appealing. This is particularly useful when working with ingredients like fruit purees or juices that can cloud the drink.
Flavor Enhancement
Egg whites can also enhance the flavors of other ingredients in the drink. The protein molecules can bind to flavor compounds, making them more intense and pronounced.

What is the purpose of adding an egg white to a cocktail?
Adding an egg white to a cocktail serves several purposes. Firstly, it adds a silky, velvety texture to the drink, making it feel more luxurious and smooth on the palate. This is especially noticeable in drinks that are typically quite spirit-forward, as the egg white helps to balance out the bold flavors and create a more harmonious taste experience.
Secondly, the egg white acts as an emulsifier, allowing the drink to hold its mixture of liquids and solids together. This is particularly important in cocktails that contain both acidic and oily ingredients, as the egg white helps to create a stable and consistent texture. By incorporating an egg white, bartenders can create complex and layered flavors that might not be possible otherwise.
Is it safe to consume raw egg whites in cocktails?
The safety of consuming raw egg whites in cocktails is a topic of concern for many. While it is true that raw eggs can pose a risk of salmonella, the risk is relatively low when handling and storing eggs properly. Furthermore, many modern cocktail bars and restaurants take steps to ensure that their eggs are sourced from reputable suppliers and handled hygienically to minimize the risk of contamination.
However, if you are still concerned about the risk, you can take steps to mitigate it. For example, you can use pasteurized eggs or egg whites, which have been treated to kill off any potential bacteria. Alternatively, you can choose to avoid raw egg whites altogether and opt for alternative emulsifiers or thickeners, such as aquafaba or orgeat syrup.
What is the difference between a “flip” and a “fizz” cocktail?
In the world of cocktails, “flip” and “fizz” are two terms that are often used to describe drinks that contain egg whites. The key difference between the two lies in the method of preparation and the resulting texture. A “flip” is a type of cocktail that is shaken without ice, resulting in a creamy, velvety texture and a thick, almost whipped-cream-like head. Flips are typically served in small, delicate glasses and are often flavored with spices, fruit, or other sweet ingredients.
A “fizz”, on the other hand, is a type of cocktail that is shaken with ice and strained into a glass, resulting in a more effervescent and bubbly texture. Fizzes are often served in taller glasses and are typically flavored with citrus, herbs, or other bright, crisp ingredients. While both flips and fizzes can be delicious and unique in their own ways, the choice between the two often comes down to personal preference and the desired texture and flavor profile.
Can I substitute egg whites with alternative ingredients?
Yes, it is possible to substitute egg whites with alternative ingredients in cocktails, although the results may vary. One popular alternative is aquafaba, the liquid from canned chickpeas, which has a similar emulsifying effect to egg whites. Other options include orgeat syrup, Simple syrup, or even gelatin, although these may not provide the same level of texture and stability as egg whites.
When substituting egg whites, it’s essential to experiment with different ratios and techniques to achieve the desired result. Keep in mind that alternative ingredients may affect the flavor and texture of the drink, so some trial and error may be necessary to get it just right.
How do I properly beat an egg white for cocktail use?
Beating an egg white for cocktail use requires some finesse and attention to detail. To start, it’s essential to use room-temperature egg whites, as this will help them incorporate air more easily and create a lighter, more stable foam. Using an electric mixer or whisk, beat the egg whites on medium to high speed until they become frothy and double in volume.
From there, you can adjust the speed and technique to achieve the desired level of foaminess and stability. Remember to stop beating once the egg whites have reached the desired consistency, as over-beating can lead to a tough, rubbery texture.
Can I make a large batch of egg whites ahead of time?
While it’s technically possible to make a large batch of egg whites ahead of time, it’s not always the best approach. Egg whites are most stable and effective when fresh and room-temperature, as refrigeration or freezing can affect their texture and ability to emulsify.
If you do need to make a large batch of egg whites ahead of time, it’s best to store them in an airtight container in the refrigerator for up to 24 hours. When you’re ready to use them, simply whip them back up to the desired consistency.
Are egg white cocktails more caloric than regular cocktails?
Egg white cocktails can indeed be more caloric than regular cocktails, although the difference is relatively small. A standard egg white contains around 17 calories, which may not seem like much, but can add up when combined with other rich and flavorful ingredients.
However, it’s worth noting that many modern egg white cocktails are designed to be more balanced and restrained in terms of sweetness and richness. By using fresh fruit, herbs, and other low-calorie ingredients, bartenders can create delicious and complex drinks that won’t break the calorie bank. As with any cocktail, moderation is key, so it’s always a good idea to keep an eye on portion sizes and ingredient ratios.
