Pavlova, a beloved dessert named after the Russian ballerina Anna Pavlova, has been a staple of Australian and New Zealand cuisine for decades. This iconic treat consists of a crisp meringue shell topped with whipped cream and an assortment of fresh fruits. However, achieving the perfect pavlova is not just about throwing together a few ingredients; it requires a deep understanding of the chemistry behind the meringue. Two ingredients that play a crucial role in creating a stable and delicious pavlova are vinegar and cornflour. In this article, we will delve into the world of pavlova and explore the importance of these two ingredients in creating the perfect meringue.
Introduction to Pavlova and Meringue
Pavlova is a type of meringue-based dessert that is known for its crisp exterior and soft interior. The meringue is made from egg whites, sugar, and cream of tartar, which are whipped together until stiff peaks form. The mixture is then baked in a slow oven until it is dry and crisp. However, pavlova is not just about the meringue; it is also about the toppings, which can range from simple whipped cream and fruit to more elaborate creations featuring nuts, chocolate, and caramel.
The Science Behind Meringue
Meringue is a fascinating substance that is made up of air bubbles suspended in a network of protein and sugar molecules. When egg whites are whipped, the proteins unwind and reorganize into a stable network that traps air bubbles. The addition of sugar helps to strengthen this network and prevent the air bubbles from collapsing. However, meringue can be a temperamental substance, and small changes in temperature, humidity, or ingredient ratios can affect its texture and stability.
The Role of Acid in Meringue
One of the key factors in creating a stable meringue is the presence of acid. Acid helps to strengthen the protein network and prevent the meringue from becoming too brittle or prone to collapse. In the case of pavlova, vinegar is often added to the meringue mixture to provide the necessary acidity. The acid in the vinegar helps to react with the proteins in the egg whites, creating a stronger and more stable network. This is especially important in pavlova, where the meringue is baked at a low temperature for a long period of time, which can cause it to dry out and become brittle.
The Importance of Vinegar in Pavlova
Vinegar is a crucial ingredient in pavlova, and its addition can make a significant difference in the texture and stability of the meringue. The acid in the vinegar helps to break down the proteins in the egg whites, creating a stronger and more stable network. This is especially important in pavlova, where the meringue is baked at a low temperature for a long period of time. Without the acidity provided by the vinegar, the meringue may become too brittle or prone to collapse.
The Effect of Vinegar on Meringue Texture
The addition of vinegar to the meringue mixture can also affect the texture of the pavlova. The acid in the vinegar helps to create a crisper exterior and a softer interior, which is characteristic of a well-made pavlova. This is because the acid helps to strengthen the protein network, allowing the meringue to hold its shape and maintain its texture. Without the vinegar, the meringue may become too dense or chewy, which can be unpleasant to eat.
Other Benefits of Vinegar in Pavlova
In addition to its effects on texture and stability, vinegar can also provide other benefits in pavlova. The acidity in the vinegar can help to balance the sweetness of the sugar and the cream, creating a more balanced flavor profile. Vinegar can also help to enhance the flavor of the fruit toppings, which is especially important in pavlova, where the fruit is a key component of the dessert.
The Role of Cornflour in Pavlova
Cornflour is another ingredient that plays a crucial role in creating a stable and delicious pavlova. Cornflour helps to absorb excess moisture in the meringue, preventing it from becoming too sticky or soft. This is especially important in pavlova, where the meringue is baked at a low temperature for a long period of time, which can cause it to dry out and become brittle. The cornflour also helps to strengthen the protein network, allowing the meringue to hold its shape and maintain its texture.
The Effect of Cornflour on Meringue Stability
The addition of cornflour to the meringue mixture can also affect the stability of the pavlova. The cornflour helps to prevent the meringue from collapsing or becoming too brittle, which can be a problem in pavlova, where the meringue is baked at a low temperature for a long period of time. This is because the cornflour helps to absorb excess moisture, preventing the meringue from becoming too sticky or soft.

What is the role of vinegar in a Pavlova meringue?
The addition of vinegar to a Pavlova meringue may seem counterintuitive, but it plays a crucial role in creating the perfect meringue. Vinegar helps to stabilize the meringue by reducing the pH level, which in turn helps to strengthen the protein bonds in the egg whites. This results in a meringue that is more stable and less prone to weeping or collapsing. The acidity of the vinegar also helps to break down the sugar, making it easier to incorporate air and creating a lighter, more even texture.
The type of vinegar used is also important, with white vinegar or white wine vinegar being the most commonly recommended. It’s essential to use a small amount of vinegar, as too much can give the meringue a sour taste. A general rule of thumb is to use about 1-2 teaspoons of vinegar per 3 egg whites. The vinegar should be added towards the end of the whipping process, once the egg whites have reached the soft peak stage. This allows the vinegar to be fully incorporated and helps to create a smooth, even texture.
How does cornflour affect the texture of a Pavlova meringue?
Cornflour, also known as cornstarch, is another essential ingredient in creating the perfect Pavlova meringue. It helps to absorb excess moisture from the egg whites, resulting in a meringue that is crispy on the outside and dry on the inside. Cornflour also helps to strengthen the protein bonds in the egg whites, making the meringue more stable and less prone to cracking. The cornflour should be sifted over the egg whites and gently folded in, taking care not to overmix.
The amount of cornflour used can vary depending on the humidity and temperature of the environment. In general, a small amount of cornflour is sufficient, with about 1-2 tablespoons being enough for 3 egg whites. It’s essential to use pure cornflour, without any added starch or ingredients, to ensure the best results. The cornflour should be added towards the end of the whipping process, once the egg whites have reached the stiff peak stage. This allows the cornflour to be fully incorporated and helps to create a smooth, even texture.
What is the ideal ratio of egg whites to sugar in a Pavlova meringue?
The ideal ratio of egg whites to sugar in a Pavlova meringue is a topic of much debate, with some recipes calling for a 1:1 ratio and others using a 1:2 or even 1:3 ratio. However, the general consensus is that a ratio of 1:2, with 1 cup of egg whites to 2 cups of sugar, produces the best results. This ratio allows for a meringue that is sweet but not too sweet, with a delicate balance of flavors.
Using the right type of sugar is also essential, with caster sugar being the most commonly recommended. Caster sugar is finer than granulated sugar, making it easier to incorporate air and creating a lighter, more even texture. It’s essential to sift the sugar over the egg whites and gently fold it in, taking care not to overmix. The sugar should be added gradually, with the egg whites being whipped to the soft peak stage before the sugar is added. This allows the sugar to be fully incorporated and helps to create a smooth, even texture.
