Cream of tartar is a common ingredient found in many recipes, particularly in baking. It is used for a variety of purposes, including stabilizing whipped cream, preventing sugar from crystallizing, and adding acidity to foods. But when it comes to egg whites, some people swear by adding cream of tartar to achieve stiff and stable peaks. But is it necessary?
In this article, we’ll delve into the science behind adding cream of tartar to egg whites and explore whether or not it’s truly beneficial. We’ll also examine alternative methods for achieving the same results, so you can decide for yourself whether or not to add this ingredient to your next batch of beaten egg whites.
What is Cream of Tartar and How Does it Affect Egg Whites?
Cream of tartar, also known as potassium bitartrate, is a white, powdery substance that is a byproduct of winemaking. It is often used as a stabilizer, leavener, and acidic ingredient in baking and cooking. When it comes to egg whites, cream of tartar helps to stabilize the egg foams. The acidity of the cream of tartar lowers the pH of the egg whites, making it easier for proteins to bond together and form a foam. This results in a more stable foam with a finer texture that traps more air bubbles.
Adding cream of tartar to egg whites is especially useful in recipes that call for the egg whites to be whipped into stiff peaks, such as meringues and angel food cake. Without the addition of cream of tartar, the egg whites can collapse and lose their structure during the mixing process or when they are baked. However, it is important to note that adding too much cream of tartar can result in an overly sour taste, so it’s best to follow the recipe’s instructions carefully or consult a trusted source.

The Science Behind Adding Cream of Tartar to Egg Whites
Adding cream of tartar to egg whites is a well-known technique for achieving that perfect texture when whipping egg whites. But what exactly does cream of tartar do to the egg whites? The answer lies in the nature of cream of tartar, which is an acidic substance. When cream of tartar is added to egg whites, it lowers the pH level of the egg whites, making them more acidic. This increased acidity makes the egg whites more stable and less likely to over-whip or deflate, allowing them to hold their shape for longer periods.
Additionally, the cream of tartar creates stronger protein bonds within the egg whites, causing them to form a more stable foam. This is due to the fact that cream of tartar helps to denature the proteins in the egg whites, causing them to unfold and form stronger bonds with one another. These stronger bonds translate into a more stable and fluffy egg white foam that is perfect for airy meringues, soufflés, and other delicate desserts.
Benefits of Adding Cream of Tartar to Egg Whites in Baking
Adding cream of tartar to egg whites while baking can significantly enhance their performance. It provides a number of benefits that make it a crucial ingredient in various baked goods. Firstly, cream of tartar helps in stabilising the egg whites, which means that they can hold their shape for a longer time. This is especially important when you’re making something like meringues or angel food cake where the egg whites need to be whipped to almost stiff peaks.
Secondly, cream of tartar helps in increasing the volume of egg whites. It does this by breaking down the egg proteins, which allows them to stretch and whip up into more volume. This means that you can use fewer eggs while still achieving the same volume as more eggs. Additionally, this aspect of cream of tartar makes it an ideal ingredient for making light, fluffy cakes and soufflés. In conclusion, the benefits of adding cream of tartar to egg whites while baking are numerous, and it’s definitely worth giving it a try to see the difference in your baking.
The Role of Cream of Tartar in Stabilizing Whipped Egg Whites
Cream of tartar is an acidic powder that is often used in combination with egg whites to stabilize them while whipping. It plays a crucial role in achieving a perfectly fluffy and stable meringue, enabling the egg whites to hold their shape and provide a light and airy texture to baked goods.
When whipped egg whites are exposed to heat, the protein molecules in the egg whites begin to unravel and denature. Cream of tartar helps to reinforce the protein structure, leading to a stiffer foam that’s less likely to deflate or collapse. Moreover, it also helps prevent the egg whites from overcooking and developing a grainy texture, by reducing the formation of large air pockets that can cause shrinkage and weeping. Therefore, cream of tartar is a key ingredient to ensure the success of recipes that rely on whipped egg whites, such as pavlova, macarons, souffles and angel food cake.
Experimenting with Cream of Tartar and Egg Whites: Tips and Tricks
When experimenting with cream of tartar and egg whites, it’s important to keep in mind that not all recipes will require the addition of cream of tartar. If you are unsure whether or not you should add cream of tartar to your egg whites, consult your recipe, or you can experiment with and without it to see what works best for you.
When adding cream of tartar to egg whites, it’s recommended that you measure it precisely. Usually, a tiny amount is sufficient to stabilize the egg whites. Also, ensure that the egg whites are at room temperature before whisking, and avoid getting any yolk in the egg whites as this can hinder the process of making them stiff. Remember that everyone has their own preference when it comes to the texture of egg whites, so don’t be discouraged if your first attempt doesn’t turn out the way you want it. Keep practicing, and soon you’ll discover the perfect method for you.
Considering Alternative Stabilizers: Cream of Tartar vs. Vinegar vs. Lemon Juice
When it comes to stabilizing egg whites, cream of tartar is not the only option. Two common alternatives are vinegar and lemon juice. Like cream of tartar, both of these acidic ingredients lower the pH of the egg whites, which helps prevent overbeating and allows the egg whites to hold their shape.
Vinegar is a potent acid that can give the egg whites a slightly tangy flavor. It is best to use white vinegar, as other types of vinegar can affect the flavor of the dish. Lemon juice, on the other hand, offers a subtle citrus flavor. It is important to note that both vinegar and lemon juice can add moisture to the egg whites, so it is best to use them sparingly and add them at the end of the whipping process. Experiment with all three options to discover which stabilizer works best for your recipe.
When to Skip the Cream of Tartar and Whip Egg Whites Without It.
While adding cream of tartar to egg whites is considered a popular technique for achieving a fluffy and voluminous meringue, it is not always necessary. If the recipe does not call for cream of tartar, skipping it will not hurt the final product. Moreover, adding too much of it can result in a tangy flavor, which may not be desirable in all recipes.
Another reason why some may choose to skip cream of tartar is if they have an allergy to it. Cream of tartar is derived from grapes, and some individuals may experience allergic reactions when consuming it. It is always important to read the label of any product you intend to consume and consult with a healthcare professional if you have any allergies or concerns.
Verdict
When it comes to whipping egg whites, cream of tartar can be a helpful addition. It helps stabilize the egg whites, allowing them to achieve a greater volume and stay fluffy for longer periods of time. Additionally, cream of tartar can help egg whites maintain their white color, a visual cue for many baked goods.
However, it is important to note that cream of tartar is not always necessary. Some recipes call for vinegar or lemon juice, which can also provide the same stabilizing effects. Ultimately, it depends on the recipe and personal preference. Experimenting with different techniques can be a fun and educational way to improve baking skills and discover new flavors and textures.
