Meringues are a classic dessert that has been delighting people for centuries. These sweet treats are made from whipped egg whites and sugar, and can be flavored and colored to create a variety of delicious variations. However, achieving the perfect meringue can be a challenge, especially for novice bakers. One secret ingredient that can make all the difference is cornflour. But what does adding cornflour do to meringue, and how can it help you create the perfect treat?
Understanding Meringues
Before we dive into the role of cornflour in meringues, it’s essential to understand the basics of meringue making. Meringues are made from three main ingredients: egg whites, sugar, and cream of tartar. The egg whites provide structure and stability, while the sugar adds sweetness and helps to strengthen the egg whites. The cream of tartar is a stabilizer that helps to strengthen the egg whites and prevent them from becoming too runny.
The Science of Meringue Making
Meringue making is a complex process that involves the manipulation of egg whites. When egg whites are whipped, they incorporate air and increase in volume. This is because the proteins in the egg whites, such as ovotransferrin and ovomucoid, unwind and reorganize into a network of strands that trap air bubbles. The sugar in the meringue mixture helps to strengthen this network of strands, making the meringue more stable and less likely to collapse.
The Role of Humidity
Humidity plays a significant role in meringue making. When the air is humid, the meringue is more likely to absorb moisture and become sticky or soft. This is because the sugar in the meringue mixture is hygroscopic, meaning it attracts moisture from the air. When the meringue absorbs too much moisture, it can become unstable and collapse.
The Benefits of Adding Cornflour to Meringue
So, what does adding cornflour do to meringue? Cornflour, also known as cornstarch, is a starchy powder that is commonly used as a thickening agent in cooking and baking. When added to meringue, cornflour can help to:
- Improve stability: Cornflour helps to strengthen the network of strands in the meringue, making it more stable and less likely to collapse.
- Reduce stickiness: Cornflour can help to absorb excess moisture in the meringue, reducing stickiness and making it easier to handle.
- Enhance texture: Cornflour can help to create a crisper, more delicate texture in the meringue, making it more appealing to eat.
How Cornflour Works in Meringue
Cornflour works in meringue by absorbing excess moisture and helping to strengthen the network of strands. When cornflour is added to the meringue mixture, it forms a complex network of starch molecules that trap air bubbles and help to strengthen the egg whites. This makes the meringue more stable and less likely to collapse.
The Science Behind Cornflour’s Effectiveness
The science behind cornflour’s effectiveness in meringue is based on the properties of starch molecules. Starch molecules are long chains of glucose molecules that are linked together in a specific pattern. When starch molecules are heated, they break down and form a gel-like substance that can trap air bubbles and help to strengthen the egg whites.
How to Add Cornflour to Meringue
Adding cornflour to meringue is a simple process that requires some basic knowledge of meringue making. Here are some tips for adding cornflour to meringue:
- Use the right ratio: The general rule of thumb is to use 1-2 tablespoons of cornflour per 3 large egg whites.
- Add cornflour to the sugar: Mix the cornflour with the sugar before adding it to the egg whites. This helps to distribute the cornflour evenly and prevents lumps from forming.
- Whip the egg whites carefully: Whip the egg whites until they become frothy, then gradually add the sugar and cornflour mixture. Continue whipping until the meringue becomes stiff and glossy.
Tips for Working with Cornflour in Meringue
Here are some additional tips for working with cornflour in meringue:
- Use a high-quality cornflour: Look for a cornflour that is finely milled and has a high starch content.
- Avoid overmixing: Overmixing can cause the cornflour to become lumpy and unevenly distributed.
- Don’t overbake: Overbaking can cause the meringue to become dry and brittle.
Conclusion
Adding cornflour to meringue can make all the difference in achieving the perfect treat. By understanding the science behind meringue making and the role of cornflour in improving stability, reducing stickiness, and enhancing texture, you can create delicious and visually appealing meringues that will impress your friends and family. Remember to use the right ratio of cornflour to egg whites, add cornflour to the sugar, and whip the egg whites carefully to achieve the best results. With practice and patience, you can master the art of meringue making and create beautiful and delicious treats that will be the envy of all who taste them.

What is the role of cornflour in meringues, and how does it contribute to their texture?
Cornflour plays a crucial role in meringues as it helps to absorb excess moisture and prevents the growth of sugar crystals, resulting in a smooth and stable meringue. When cornflour is added to the meringue mixture, it absorbs the excess moisture from the egg whites and sugar, allowing the meringue to dry out faster and more evenly. This helps to prevent the meringue from becoming too sticky or chewy.
The addition of cornflour also helps to strengthen the structure of the meringue, making it more stable and less prone to collapse. This is especially important when making large or intricate meringue designs, as it allows the meringue to hold its shape and maintain its texture. By incorporating cornflour into the meringue mixture, bakers can achieve a lighter, crisper, and more delicate texture that is characteristic of perfect meringues.
How much cornflour should I add to my meringue recipe, and what type of cornflour is best to use?
The amount of cornflour to add to a meringue recipe can vary depending on the specific recipe and the desired texture. As a general rule, it’s best to start with a small amount of cornflour, such as 1-2 tablespoons per 3 large egg whites, and adjust to taste. Too much cornflour can make the meringue taste starchy or chalky, while too little may not provide enough structure and stability.
When it comes to choosing a type of cornflour, it’s best to use a fine or superfine cornflour that is specifically designed for baking. This type of cornflour is usually made from cornstarch that has been finely milled to produce a smooth and powdery texture. Avoid using coarse or stone-ground cornflour, as it can leave a gritty texture in the meringue. Some popular brands of cornflour for baking include cornstarch, tapioca flour, or potato starch.
Can I omit the cornflour from my meringue recipe, or substitute it with another ingredient?
While it’s technically possible to omit the cornflour from a meringue recipe, it’s not recommended. Cornflour plays a crucial role in absorbing excess moisture and preventing the growth of sugar crystals, and omitting it can result in a meringue that is sticky, chewy, or prone to collapse. If you don’t have cornflour on hand, it’s better to substitute it with another ingredient that provides similar properties, such as tapioca flour or potato starch.
When substituting cornflour with another ingredient, it’s essential to use a 1:1 ratio to ensure that the meringue turns out correctly.
