Meringue, a sweet and airy confection, has been a staple in many desserts for centuries. Its light and fluffy texture, often accompanied by a crunchy exterior, makes it a favorite among pastry enthusiasts. However, a common question arises when it comes to meringue: is it raw or cooked? In this article, we will delve into the world of meringue, exploring its history, preparation methods, and the science behind its texture. By the end of this journey, you will have a deeper understanding of meringue and be able to answer the question with confidence.
A Brief History of Meringue
Meringue has its roots in 16th-century Switzerland, where it was known as “biscuit de meringue.” The name “meringue” is believed to have originated from the town of Meiringen, where the dessert was first created. Initially, meringue was made from whipped egg whites and sugar, which were then baked in a slow oven to create a crispy exterior and a soft interior.
Over time, meringue spread throughout Europe, with different countries adapting their own unique recipes and techniques. In France, meringue became a staple in many patisseries, where it was used to create elaborate desserts such as meringue pies and cakes. In Italy, meringue was used to make a popular dessert called “panna cotta,” which consists of sweetened cream topped with a layer of meringue.
The Preparation of Meringue
Meringue is typically made from three main ingredients: egg whites, sugar, and cream of tartar. The egg whites are whipped until they become stiff and frothy, at which point the sugar and cream of tartar are added. The mixture is then whipped further until it becomes smooth and glossy.
There are three main types of meringue: French, Italian, and Swiss. French meringue is the most common type and is made by whipping egg whites and sugar until stiff peaks form. Italian meringue is made by whipping egg whites and a hot sugar syrup until stiff peaks form. Swiss meringue is made by whipping egg whites and sugar over a double boiler until stiff peaks form.
Cooking Methods
Meringue can be cooked in a variety of ways, depending on the desired texture and consistency. Here are some common cooking methods:
- Baking: Meringue can be baked in a slow oven (150°F – 200°F) for 1-2 hours, or until crispy and dry. This method is often used to make meringue cookies and wafers.
- Broiling: Meringue can be broiled for a few seconds on each side, or until golden brown. This method is often used to make meringue toppings for pies and cakes.
- Grilling: Meringue can be grilled over low heat for a few minutes on each side, or until golden brown. This method is often used to make meringue toppings for desserts such as banana splits.
The Science Behind Meringue
Meringue is a fascinating dessert that relies on the principles of chemistry and physics to create its unique texture. Here are some key factors that contribute to the texture of meringue:
- Protein structure: Egg whites are made up of proteins such as ovotransferrin and ovomucoid. When egg whites are whipped, these proteins unwind and reorganize into a network of strands that trap air bubbles. This network of strands gives meringue its structure and texture.
- Sugar concentration: Sugar plays a crucial role in the texture of meringue. When sugar is added to egg whites, it helps to strengthen the protein network and create a more stable foam. However, too much sugar can make the meringue too dense and brittle.
- Moisture content: Meringue is sensitive to moisture, which can cause it to become sticky and soft. When meringue is exposed to high humidity, the air bubbles within the protein network can collapse, causing the meringue to lose its texture.
The Role of Heat
Heat plays a crucial role in the cooking of meringue. When meringue is exposed to heat, the proteins within the egg whites denature and coagulate, creating a more stable foam. However, too much heat can cause the meringue to become overcooked and brittle.
In the case of baked meringue, the heat from the oven causes the proteins to denature and coagulate, creating a crispy exterior and a soft interior. In the case of broiled or grilled meringue, the heat causes the proteins to denature and coagulate, creating a golden-brown exterior and a soft interior.
Is Meringue Raw or Cooked?
Now that we have explored the history, preparation, and science behind meringue, we can answer the question: is meringue raw or cooked?
The answer depends on the cooking method used. If meringue is baked, broiled, or grilled, it is considered cooked. However, if meringue is not exposed to heat, it is considered raw.
Raw meringue is often used as a topping for desserts such as pies and cakes. It is also used as a base for desserts such as meringue cookies and wafers. However, raw meringue can pose a risk of salmonella poisoning, as it contains raw egg whites. To minimize this risk, it is recommended to use pasteurized egg whites or to cook the meringue to an internal temperature of 160°F.
Food Safety Considerations
When working with meringue, it is essential to consider food safety. Here are some tips to minimize the risk of salmonella poisoning:
- Use pasteurized egg whites: Pasteurized egg whites have been heated to a temperature that kills bacteria such as salmonella.

Is Meringue Considered a Raw or Cooked Food?
Meringue is often misunderstood as being a raw food due to its primary ingredient, egg whites. However, the process of making meringue involves heating the egg whites to a temperature that is sufficient to kill bacteria and cook the proteins. This process, known as denaturation, occurs when the egg whites are whipped and heated, either through the addition of hot sugar or by baking in a low-temperature oven.
The heat from the sugar or oven causes the proteins in the egg whites to unwind and reorganize into a more stable structure, which gives meringue its characteristic texture and stability. This process is a form of cooking, even though it may not involve high temperatures or prolonged heating times. As a result, meringue can be considered a cooked food, despite its delicate and airy texture.
What Happens to the Egg Whites During the Meringue-Making Process?
During the meringue-making process, the egg whites undergo a significant transformation. When egg whites are first whipped, they incorporate air and increase in volume, becoming frothy and bubbly. As the whipping continues, the proteins in the egg whites begin to unwind and reorganize, forming a network of strands that trap air bubbles and give the meringue its structure.
As the egg whites are heated, either through the addition of hot sugar or by baking in a low-temperature oven, the proteins continue to denature and coagulate, forming a more stable and rigid structure. This process causes the meringue to become more dense and firm, with a smooth and glossy appearance. The heat also helps to kill any bacteria that may be present in the egg whites, making the meringue safe to eat.
Is It Safe to Eat Meringue Made with Raw Egg Whites?
It is generally not recommended to eat meringue made with raw egg whites, as there is a risk of salmonella poisoning. Raw egg whites can contain salmonella bacteria, which can cause serious food poisoning if ingested. While the risk of salmonella poisoning from raw egg whites is relatively low, it is still important to take precautions to minimize the risk.
To make meringue safely, it is recommended to use pasteurized egg whites or to heat the egg whites to an internal temperature of at least 160°F (71°C) during the cooking process. This can be achieved by adding hot sugar to the egg whites or by baking the meringue in a low-temperature oven. By taking these precautions, you can enjoy meringue while minimizing the risk of food poisoning.
How Does the Type of Sugar Used Affect the Cooking of Meringue?
The type of sugar used in meringue can affect the cooking process and the final texture of the meringue. Granulated sugar is the most commonly used sugar in meringue, as it dissolves easily and provides a smooth texture. However, other types of sugar, such as brown sugar or turbinado sugar, can be used to create a slightly different flavor and texture.
The type of sugar used can also affect the cooking time and temperature of the meringue. For example, meringue made with brown sugar may require a slightly lower oven temperature and a longer cooking time to prevent the sugar from caramelizing. By choosing the right type of sugar for your meringue, you can achieve the desired texture and flavor.
Can Meringue Be Made Without Cooking the Egg Whites?
While it is possible to make meringue without cooking the egg whites, it is not recommended. Raw egg whites can contain salmonella bacteria, which can cause serious food poisoning if ingested. Additionally, raw egg whites may not provide the same level of stability and structure as cooked egg whites, resulting in a meringue that is more prone to weeping or collapse.
To make meringue safely and effectively, it is recommended to use pasteurized egg whites or to heat the egg whites to an internal temperature of at least 160°F (71°C) during the cooking process. This can be achieved by adding hot sugar to the egg whites or by baking the meringue in a low-temperature oven. By cooking the egg whites, you can create a meringue that is both safe to eat and stable in texture.
What Is the Role of Acidic Ingredients in Meringue?
Acidic ingredients, such as cream of tartar or lemon juice, play an important role in meringue by helping to stabilize the egg whites and create a smooth, glossy texture. The acid helps to strengthen the bonds between the proteins in the egg whites, making the meringue more stable and less prone to weeping or collapse.
The acid also helps to balance the pH of the meringue, which can affect the texture and stability of the final product. By adding a small amount of acidic ingredient to the egg whites, you can create a meringue that is both stable and smooth, with a delicate and airy texture.
How Does the Cooking Time and Temperature Affect the Texture of Meringue?
The cooking time and temperature of meringue can significantly affect the texture of the final product. If the meringue is undercooked, it may be soft and sticky, while overcooking can cause it to become dry and brittle. The ideal cooking time and temperature will depend on the specific recipe and the desired texture of the meringue.
In general, meringue is best cooked at a low temperature, around 200°F (90°C), for a longer period of time, such as 1-2 hours. This allows the egg whites to cook slowly and evenly, resulting in a smooth and stable texture. By controlling the cooking time and temperature, you can create a meringue that is both delicate and crispy, with a smooth and glossy appearance.
