As bakers, we’ve all been there – meticulously following a recipe, only to be left wondering about the purpose of certain ingredients or techniques. One such mystery is the egg wash, a common practice in baking that involves brushing a mixture of beaten eggs and water onto pastry dough before baking. But does egg wash really do anything, or is it just a redundant step in the baking process? In this article, we’ll delve into the world of egg washes, exploring their history, benefits, and potential drawbacks.
A Brief History of Egg Washes
Egg washes have been a staple in baking for centuries, with evidence of their use dating back to medieval Europe. During this time, bakers used egg washes to add color and shine to breads and pastries, as well as to create intricate designs and patterns. The practice was particularly popular among artisanal bakers, who used egg washes to add a personal touch to their creations.
The Science Behind Egg Washes
So, what exactly happens when we apply an egg wash to pastry dough? The answer lies in the chemistry of eggs. Egg washes are typically made by beating eggs with water, which breaks down the proteins and fats in the eggs. When applied to pastry dough, the egg wash forms a thin, golden-brown crust on the surface of the pastry. This crust, known as the “glaze,” serves several purposes:
- Browning: The egg wash helps to create a rich, golden-brown color on the surface of the pastry, which is achieved through a process called the Maillard reaction. This reaction occurs when the amino acids and sugars in the eggs react with the heat of the oven, producing new flavor compounds and browning the pastry.
- Moisture: The egg wash helps to retain moisture in the pastry, keeping it fresh and tender for longer. This is especially important for delicate pastries, such as croissants and danishes.
- Gloss: The egg wash adds a glossy finish to the pastry, which can enhance its appearance and make it more appealing to consumers.
Benefits of Using Egg Washes
Now that we’ve explored the science behind egg washes, let’s take a look at their benefits in baking:
- Improved appearance: Egg washes can add a rich, golden-brown color to pastries, making them more visually appealing.
- Enhanced flavor: The Maillard reaction that occurs when the egg wash is exposed to heat can produce new flavor compounds, adding depth and complexity to the pastry.
- Increased moisture: The egg wash helps to retain moisture in the pastry, keeping it fresh and tender for longer.
- Better texture: The egg wash can help to create a crispy, flaky texture on the surface of the pastry, which can add to its overall appeal.
Common Uses for Egg Washes
Egg washes are a versatile ingredient that can be used in a variety of baked goods, including:
- Breads: Egg washes can be used to add color and shine to breads, as well as to create intricate designs and patterns.
- Pastries: Egg washes are a staple in pastry baking, where they’re used to add a golden-brown color and a crispy, flaky texture to pastries.
- Pies: Egg washes can be used to add a glossy finish to pie crusts, as well as to create a decorative border around the edges of the pie.
Drawbacks of Using Egg Washes
While egg washes can be a valuable tool in baking, there are some potential drawbacks to consider:
- Added calories: Egg washes can add extra calories to baked goods, which can be a concern for health-conscious consumers.
- Allergies: Eggs are a common allergen, which can make egg washes a problem for bakers who need to accommodate customers with egg allergies.
- Cost: Eggs can be expensive, especially if you’re using high-quality, farm-fresh eggs. This can add to the overall cost of your baked goods.

What is an egg wash, and how is it used in baking?
An egg wash is a mixture of beaten eggs and a small amount of liquid, such as water or milk, used to brush the surface of baked goods before baking. The egg wash serves as a glaze, adding color, shine, and texture to the finished product. It is commonly used on breads, pastries, and other sweet and savory baked goods.
The egg wash is typically applied to the dough or pastry using a brush, making sure to cover the entire surface evenly. The amount of egg wash used can vary depending on the desired intensity of the glaze. Some bakers also add a pinch of salt or a teaspoon of sugar to the egg wash to enhance the flavor and texture of the finished product.
Does an egg wash really do anything in baking, or is it just a myth?
Contrary to popular belief, an egg wash does more than just add a golden brown color to baked goods. It also helps to create a crispy, caramelized crust on the surface of the bread or pastry. The proteins in the egg wash help to strengthen the gluten network in the dough, resulting in a more tender and flaky texture.
Additionally, the egg wash can help to create a barrier against moisture, preventing the baked goods from becoming soggy or stale too quickly. This is especially important for baked goods that are exposed to high humidity or moisture, such as breads and pastries. Overall, the egg wash plays a significant role in enhancing the texture, flavor, and appearance of baked goods.
What are the benefits of using an egg wash in baking?
Using an egg wash in baking offers several benefits, including a golden brown color, a crispy and caramelized crust, and a tender and flaky texture. The egg wash also helps to create a barrier against moisture, preventing the baked goods from becoming soggy or stale too quickly.
In addition to these benefits, the egg wash can also help to enhance the flavor of the baked goods. The proteins in the egg wash can help to strengthen the gluten network in the dough, resulting in a more complex and developed flavor. Overall, the egg wash is a simple and effective way to take your baked goods to the next level.
Can I make an egg wash with just egg whites or egg yolks?
Yes, you can make an egg wash with just egg whites or egg yolks, depending on the desired color and texture. An egg wash made with just egg whites will produce a lighter, more delicate color and a crisper texture. On the other hand, an egg wash made with just egg yolks will produce a richer, more golden color and a more tender texture.
However, it’s worth noting that using just egg whites or egg yolks can affect the overall flavor and texture of the baked goods. Egg whites contain more protein than egg yolks, which can help to strengthen the gluten network in the dough. Egg yolks, on the other hand, contain more fat and cholesterol, which can add richness and depth to the flavor of the baked goods.
How do I make an egg wash, and what is the right consistency?
To make an egg wash, simply beat one or two eggs with a small amount of liquid, such as water or milk, until the mixture is smooth and well combined. The right consistency for an egg wash is thin enough to brush easily onto the surface of the dough or pastry, but not so thin that it becomes too watery.
A good rule of thumb is to start with a small amount of liquid and add more as needed to achieve the right consistency. You can also add a pinch of salt or a teaspoon of sugar to the egg wash to enhance the flavor and texture of the finished product. It’s also important to whisk the egg wash thoroughly to ensure that the eggs are fully incorporated and the mixture is smooth and even.
Can I use an egg wash on all types of baked goods?
While an egg wash can be used on a variety of baked goods, it’s not suitable for all types of baking. For example, an egg wash can be too rich and overpowering for delicate pastries or cakes. In these cases, a lighter glaze or a simple dusting of powdered sugar may be more effective.
On the other hand, an egg wash is particularly well suited for breads, rolls, and other savory baked goods. It can also be used on sweet breads and pastries, such as croissants and danishes, to add a golden brown color and a crispy texture. Ultimately, the decision to use an egg wash will depend on the type of baked goods and the desired texture and flavor.
Are there any alternatives to using an egg wash in baking?
Yes, there are several alternatives to using an egg wash in baking, depending on the desired color and texture. For example, a mixture of milk and melted butter can be used to create a golden brown color and a crispy texture. A beaten egg substitute, such as Ener-G Egg Replacer or flaxseed, can also be used to create a similar texture and flavor.
Additionally, some bakers use a mixture of water and cornstarch or flour to create a glaze that is similar to an egg wash. This mixture can be brushed onto the surface of the dough or pastry to create a crispy and caramelized crust. Ultimately, the choice of alternative will depend on the type of baked goods and the desired texture and flavor.
