When it comes to baking a pie, one of the most crucial steps is brushing the crust with a liquid to give it a golden brown finish. Two popular options for this step are egg and milk, but which one should you use? In this article, we’ll delve into the world of pie crust brushing, exploring the benefits and drawbacks of using egg and milk, as well as some alternative options.
Understanding the Role of Brushing in Pie Crust
Brushing the pie crust serves several purposes:
- It helps to create a golden brown color, which is not only visually appealing but also indicates that the crust is cooked through.
- It adds flavor to the crust, depending on the liquid used.
- It helps to create a crispy texture, especially when using egg.
The Science Behind Brushing
When you brush the pie crust with a liquid, it creates a barrier between the crust and the filling. This barrier helps to prevent the filling from seeping into the crust, making it soggy. The liquid also helps to create a Maillard reaction, a chemical reaction between amino acids and reducing sugars that occurs when the crust is exposed to heat. This reaction is responsible for the golden brown color and crispy texture of the crust.
Egg vs. Milk: Which is Better for Brushing Pie Crust?
Both egg and milk are popular options for brushing pie crust, but they have some key differences.
Egg: The Benefits and Drawbacks
Using egg to brush pie crust has several benefits:
- Rich, golden brown color: Egg contains proteins and fats that help to create a rich, golden brown color when exposed to heat.
- Crispy texture: The proteins in egg help to create a crispy texture on the surface of the crust.
- Flavor: Egg can add a slightly nutty flavor to the crust.
However, there are also some drawbacks to using egg:
- Overpowering flavor: If you’re using a delicate filling, the flavor of the egg can overpower it.
- Risk of over-browning: If you’re not careful, the egg can cause the crust to brown too quickly, leading to an overcooked crust.
Milk: The Benefits and Drawbacks
Using milk to brush pie crust has several benefits:
- Subtle flavor: Milk has a subtle flavor that won’t overpower the filling.
- Even browning: Milk helps to create an even, golden brown color on the crust.
- Moisture: Milk can help to keep the crust moist, especially if you’re using a dry filling.
However, there are also some drawbacks to using milk:
- Less crispy texture: Milk doesn’t contain the same proteins as egg, so it won’t create a crispy texture on the surface of the crust.
- Less golden brown color: Milk can create a lighter, more pale color on the crust compared to egg.
Alternative Options for Brushing Pie Crust
If you’re looking for alternative options to egg and milk, there are several other liquids you can use:
- Water: Water is a good option if you want to create a crust with a light, delicate flavor. However, it won’t add much color or texture to the crust.
- Cream: Cream is a good option if you want to add a rich, creamy flavor to the crust. However, it can make the crust more prone to burning.
- Butter: Melted butter can be used to brush the crust, adding a rich, nutty flavor. However, it can make the crust more prone to burning.
When to Use Each Option
Here are some general guidelines for when to use each option:
- Egg: Use egg when you want to create a crust with a rich, golden brown color and a crispy texture. It’s a good option for savory pies, such as quiches or pot pies.
- Milk: Use milk when you want to create a crust with a subtle flavor and an even, golden brown color. It’s a good option for sweet pies, such as apple or pumpkin pies.
- Alternative options: Use alternative options when you want to add a unique flavor or texture to the crust. For example, you could use cream to add a rich, creamy flavor to a sweet pie.
Best Practices for Brushing Pie Crust
Regardless of which liquid you choose, there are some best practices to keep in mind when brushing pie crust:
- Use a light touch: Brush the crust lightly, making sure not to overload it with liquid. This can cause the crust to become soggy or unevenly cooked.
- Brush in one direction: Brush the crust in one direction, following the lines of the crust. This helps to create a smooth, even texture.
- Don’t over-brush: Don’t over-brush the crust, as this can cause it to become too brown or crispy.
Tips for Achieving the Perfect Finish
Here are some tips for achieving the perfect finish on your pie crust:
- Use a pastry brush: A pastry brush is a specialized brush that’s designed specifically for brushing pie crust. It has soft bristles that won’t scratch the crust.
- Chill the crust: Chilling the crust before baking can help it to hold its shape and create a flaky texture.
- Bake at the right temperature: Baking the pie at the right temperature can help to create a golden brown color and a crispy texture.

Brushing pie crust is an important step in creating a delicious, visually appealing pie. Whether you choose to use egg, milk, or an alternative option, the key is to use a light touch and to brush in one direction.

What is the purpose of brushing pie crust with egg or milk?
Brushing pie crust with egg or milk serves several purposes. Firstly, it helps to create a golden-brown finish on the crust, which can enhance the overall appearance of the pie. This is especially important for pies that are meant to be visually appealing, such as those served at special occasions or holidays. Additionally, the egg or milk wash can help to strengthen the crust and prevent it from becoming too brittle or prone to cracking.
The egg or milk wash can also help to create a barrier between the crust and the filling, which can prevent the crust from becoming soggy or absorbing too much moisture. This is especially important for pies with wet or runny fillings, such as pumpkin or cherry pie. By brushing the crust with egg or milk, you can help to create a crispy, flaky texture that complements the filling perfectly.
What are the differences between using egg and milk to brush pie crust?
The main difference between using egg and milk to brush pie crust is the richness and color of the finish. Egg washes tend to produce a richer, more golden-brown color, while milk washes produce a lighter, more subtle finish. Egg washes are also more likely to create a crispy, caramelized texture on the crust, while milk washes tend to produce a softer, more delicate texture.
In terms of functionality, egg washes are often preferred for pies with wet or runny fillings, as they provide a stronger barrier against moisture. Milk washes, on the other hand, are often preferred for pies with dry or flaky fillings, as they help to create a more delicate, tender texture. Ultimately, the choice between egg and milk will depend on the type of pie you are making and the desired finish.
How do I make an egg wash for brushing pie crust?
To make an egg wash for brushing pie crust, you will need one egg and a small amount of water. Beat the egg lightly in a small bowl, then add a tablespoon or two of water to thin it out. The egg wash should be smooth and free of lumps, with a consistency that is similar to thin paint. You can adjust the amount of water to achieve the desired consistency, but be careful not to add too much, as this can make the egg wash too thin and difficult to work with.
Once you have made the egg wash, use a pastry brush to apply it evenly to the pie crust. Make sure to cover the entire surface of the crust, but avoid getting the egg wash too close to the edges, as this can cause the crust to become too brown or crispy.
