When it comes to baking, there are few techniques as crucial as the humble egg wash. A simple mixture of beaten eggs and liquid, the egg wash is a game-changer for pastry enthusiasts, adding a golden sheen, flaky texture, and unparalleled flavor to a wide range of baked goods. But what exactly does egg wash do to pastry, and how can you harness its power to take your baking to the next level?
What is Egg Wash, and How is it Made?
At its core, an egg wash is a mixture of beaten eggs and a liquid, typically water or milk. The eggs are beaten until they become light and frothy, then mixed with the liquid to create a smooth, creamy consistency. The ratio of eggs to liquid can vary depending on the desired thickness and richness of the wash, but a general rule of thumb is to use one egg per tablespoon of liquid.
The type of liquid used can also impact the final result. Water is a common choice, as it adds moisture and helps to create a smooth, even finish. Milk, on the other hand, adds a touch of richness and can enhance the flavor of the pastry. Some bakers also swear by using cream or butter for an extra-decadent egg wash.
The Science Behind Egg Wash
So, what makes egg wash so magical? The answer lies in the science behind the mixture. When eggs are beaten, the proteins and fats within the egg whites and yolks are broken down and reorganized, creating a network of strands that give the egg wash its structure and strength.
When the egg wash is applied to pastry, these strands help to create a barrier between the pastry and the heat of the oven. This barrier, known as a “crust,” helps to prevent the pastry from becoming too brown or overcooked, while also adding a golden sheen and crispy texture.
In addition to its structural benefits, egg wash also plays a crucial role in browning. The proteins and fats within the egg wash react with the heat of the oven to produce a rich, golden color, adding depth and visual appeal to the finished pastry.
The Benefits of Using Egg Wash
So, why should you use egg wash in your pastry-making endeavors? The benefits are numerous, and can be broken down into several key areas:
Appearance
- Golden color: Egg wash adds a rich, golden sheen to pastry, making it more visually appealing and appetizing.
- Crispy texture: The barrier created by the egg wash helps to produce a crispy, flaky texture that is both delicious and satisfying.
Flavor
- Enhanced flavor: Egg wash can add a rich, savory flavor to pastry, particularly when used in combination with other ingredients like herbs and spices.
- Moisture: The liquid within the egg wash helps to keep the pastry moist and tender, even when baked to a golden brown.
Structure
- Flaky texture: The strands within the egg wash help to create a flaky, layered texture that is both tender and crispy.
- Strength: The egg wash helps to add strength and structure to the pastry, making it less prone to breakage and cracking.
Common Uses for Egg Wash
Egg wash is a versatile ingredient that can be used in a wide range of pastry applications. Some common uses include:
Savory Pastries

- Fruit pies and tarts: Egg wash helps to create a flaky, tender crust on fruit pies and tarts, while also adding a touch of sweetness and flavor.
Tips and Tricks for Working with Egg Wash
While egg wash is a relatively simple ingredient to work with, there are a few tips and tricks to keep in mind:
Brushing the Egg Wash
- Use a gentle touch: When brushing the egg wash onto the pastry, use a gentle touch to avoid damaging the delicate layers.
- Brush in one direction: Brush the egg wash in one direction only, following the lines of the pastry to create a smooth, even finish.
Choosing the Right Egg Wash
- Whole eggs or egg yolks: Whole eggs produce a richer, more golden egg wash, while egg yolks create a deeper, more orange color.
- Water or milk: Water produces a lighter, more delicate egg wash, while milk adds a touch of richness and flavor.

What is an egg wash and how is it used in pastry-making?
An egg wash is a mixture of beaten eggs and liquid, typically water or milk, used to brush pastry dough before baking. The egg wash serves as a glaze, adding color, shine, and flavor to the pastry. It can also help to create a golden-brown crust and enhance the overall appearance of the pastry.
The egg wash is usually applied to the pastry dough after it has been shaped and placed on a baking sheet. A pastry brush is used to gently brush the egg wash onto the dough, making sure to cover the entire surface evenly. The egg wash can be applied in a thin or thick layer, depending on the desired effect.
What are the benefits of using an egg wash in pastry-making?
Using an egg wash in pastry-making offers several benefits. Firstly, it helps to create a golden-brown crust, which adds flavor and texture to the pastry. The egg wash also helps to seal the edges of the pastry, preventing filling from escaping during baking. Additionally, the egg wash can help to create a flaky, tender crust, which is a characteristic of high-quality pastry.
The egg wash can also be used to add flavor to the pastry. For example, herbs and spices can be added to the egg wash to give the pastry a unique flavor. The egg wash can also be used to create a decorative edge on the pastry, adding a touch of elegance to the finished product.
How do I make an egg wash for pastry-making?
To make an egg wash for pastry-making, you will need eggs, liquid, and a pinch of salt. The eggs should be beaten until they are well-mixed and smooth. The liquid, which can be water or milk, should be added to the eggs in a ratio of about 1 part liquid to 1 part egg. The mixture should be whisked until it is smooth and free of lumps.
The egg wash can be made ahead of time and stored in the refrigerator for up to a day. Before using the egg wash, it should be allowed to come to room temperature. This will help the egg wash to brush on smoothly and evenly.
Can I use a different type of wash instead of an egg wash?
Yes, there are several alternatives to an egg wash that can be used in pastry-making. One option is a milk wash, which is made by brushing milk onto the pastry dough before baking. A milk wash can add a rich, creamy flavor to the pastry and help to create a golden-brown crust.
