Thickening pastry cream is an essential skill for any baker or pastry chef, as it can make or break the texture and overall quality of a dessert. Pastry cream, also known as crème pâtissière, is a rich and creamy filling used in a variety of sweet treats, from éclairs and cream puffs to cakes and tarts. However, achieving the perfect consistency can be a challenge, especially for beginners. In this article, we will delve into the world of pastry cream and explore the various methods and techniques for thickening it to perfection.
Understanding Pastry Cream
Before we dive into the thickening process, it’s essential to understand the basics of pastry cream. Pastry cream is a mixture of milk, sugar, eggs, and flavorings, such as vanilla or chocolate, that is cooked together to create a smooth and creamy texture. The ratio of ingredients and the cooking method can vary depending on the desired consistency and flavor profile. The key to making great pastry cream is to cook it slowly and gently, stirring constantly, to prevent the eggs from scrambling and the milk from boiling over.
The Importance of Temperature and Cooking Time
Temperature and cooking time play a crucial role in thickening pastry cream. The ideal temperature for cooking pastry cream is between 170°F and 180°F, as this allows the eggs to cook slowly and the starches to break down, resulting in a smooth and creamy texture. Cooking the cream for too short a time can result in a runny consistency, while overcooking can cause it to become too thick and scrambled.
The Role of Starches in Thickening
Starches, such as cornstarch or flour, are commonly used to thicken pastry cream. Starches work by absorbing excess liquid and expanding, which helps to thickening the cream. The type and amount of starch used can vary depending on the desired consistency and flavor profile. For example, cornstarch is a popular choice for thickening pastry cream, as it is odorless and flavorless, while flour can add a slightly nutty flavor.
Methods for Thickening Pastry Cream
There are several methods for thickening pastry cream, each with its own advantages and disadvantages. The most common methods include using starches, reducing the cream, and using eggs. In this section, we will explore each of these methods in more detail and provide tips and techniques for achieving the perfect consistency.
Using Starches to Thicken Pastry Cream
Using starches is one of the most common methods for thickening pastry cream. To use starches, simply mix a small amount of starch with a little cold water or milk to create a slurry, then add it to the pastry cream and cook for a few minutes, stirring constantly. The starch will absorb excess liquid and help to thicken the cream. It’s essential to use the right amount of starch, as too much can result in a thick and starchy consistency, while too little may not provide enough thickening power.
Reducing the Cream
Another method for thickening pastry cream is to reduce the cream by cooking it for a longer period. This method involves cooking the cream over low heat, stirring constantly, until it has reduced and thickened to the desired consistency. Reducing the cream can be a time-consuming process, but it allows for a high level of control over the final consistency and flavor profile.
Using Eggs to Thicken Pastry Cream
Eggs are a natural thickening agent and can be used to thicken pastry cream. To use eggs, simply beat them lightly and temper them by slowly adding a small amount of the warm pastry cream, then return the mixture to the heat and cook, stirring constantly, until the cream has thickened. Using eggs can add richness and depth to the pastry cream, but it’s essential to temper them properly to prevent the eggs from scrambling.
Tips and Techniques for Thickening Pastry Cream
In addition to the methods outlined above, there are several tips and techniques that can help to thicken pastry cream to perfection. One of the most important tips is to cook the cream slowly and gently, stirring constantly, to prevent the eggs from scrambling and the milk from boiling over. It’s also essential to use the right type and amount of starch, as well as to not overcook the cream, which can result in a thick and starchy consistency.

What is pastry cream and how is it used in baking?
Pastry cream, also known as crème pâtissière, is a rich and creamy filling used in a variety of baked goods, such as eclairs, cream puffs, and napoleons. It is made with a mixture of milk, sugar, eggs, and flavorings, which are cooked together to create a smooth and velvety texture. Pastry cream is a fundamental component of many French pastries and desserts, and its thickening properties are crucial to achieving the right consistency and texture.
The thickening properties of pastry cream are what set it apart from other types of fillings and creams. When made correctly, pastry cream should be thick enough to hold its shape, but still be light and airy. This is achieved through the use of eggs, which provide structure and richness to the cream, and the cooking process, which involves heating the mixture to a specific temperature to activate the eggs and thicken the cream. By mastering the art of thickening pastry cream, bakers can create a wide range of delicious and visually appealing desserts that are sure to impress.
What are the key ingredients in pastry cream and how do they contribute to its thickening properties?

The cream should also be kept at a consistent refrigerated temperature, between 39°F and 41°F, to prevent the growth of bacteria and other microorganisms.
To maintain the quality and texture of pastry cream, bakers should also avoid exposing it to heat, light, or moisture, which can cause the cream to break or become too thin. When using pastry cream to fill cakes or pastries, it’s essential to work quickly and efficiently, to prevent the cream from warming up or absorbing too much moisture from the air. By following proper storage and handling procedures, bakers can maintain the quality and texture of their pastry cream and ensure that it remains fresh and delicious for a longer period.
Can I make pastry cream ahead of time and freeze it for later use?
Yes, pastry cream can be made ahead of time and frozen for later use. In fact, freezing is a great way to preserve the cream and maintain its quality and texture. To freeze pastry cream, bakers should cool it to room temperature, then transfer it to an airtight container or freezer bag. The cream can be frozen for up to 3 months, and when thawed, it should be refrigerated and used within a day or two.
When freezing pastry cream, bakers should be aware that the cream may undergo some changes in texture and consistency. The cream may become slightly thicker and more ice-like, but it should still be smooth and creamy when thawed. To restore the cream to its original texture, bakers can whisk it gently after thawing, or add a small amount of milk or cream to thin it out. By making pastry cream ahead of time and freezing it, bakers can save time and effort, and have a convenient and delicious filling on hand for future baking projects.
