What Is Cream of Tartar For?
Cream of tartar is primarily used in the kitchen as a stabilizer for whipped egg whites, preventing sugar crystallization, and as a leavening agent when combined with baking soda. It also has other, less common applications, ranging from cleaning to easing certain medical conditions.
The Surprising Versatility of Cream of Tartar: More Than Just Baking
Cream of tartar, scientifically known as potassium bitartrate or potassium hydrogen tartrate, is a white, powdery byproduct of winemaking. Found as a crust on the inside of wine barrels, it might seem an unlikely culinary aid and household helper. However, its unique chemical properties make it an invaluable ingredient in a variety of applications.
Cream of Tartar in Baking: A Culinary Cornerstone
The most common use for cream of tartar is undoubtedly in baking. Its role in achieving the perfect meringue or preventing sugar from forming crystals in candies makes it a pantry staple for many bakers.
- Stabilizing Egg Whites: Cream of tartar strengthens the protein network in egg whites as they are whipped, creating a more stable and voluminous meringue. This is crucial for achieving airy and light desserts such as angel food cake and soufflés.
- Preventing Sugar Crystallization: In candies, syrups, and frostings, cream of tartar interferes with the formation of large sugar crystals, resulting in a smoother and more desirable texture. It helps maintain the creamy consistency and prevents a gritty mouthfeel.
- Leavening Agent: When combined with baking soda, cream of tartar acts as a leavening agent, producing carbon dioxide gas that helps baked goods rise. This is the basis of baking powder, which is simply a mixture of cream of tartar, baking soda, and a drying agent.
Beyond Baking: Unexpected Uses for Cream of Tartar
While baking is its most prominent application, cream of tartar has a surprising number of other uses, from household cleaning to potential health benefits.
- Cleaning Agent: Cream of tartar’s mildly acidic nature makes it an effective cleaning agent. It can be used to remove stains from stainless steel, porcelain, and even clothing.
- Brightening Laundry: Adding a small amount of cream of tartar to your laundry can help brighten whites and remove dinginess.
- Preventing Vegetables from Discoloring: When boiling vegetables like cauliflower and potatoes, adding a pinch of cream of tartar can help prevent them from turning brown or gray.
- Potential Health Benefits: Some people believe that cream of tartar can help with certain health issues, although scientific evidence is limited. These include treating urinary tract infections and quitting smoking. It is important to note that these uses are not scientifically proven and should be discussed with a healthcare professional.
How to Use Cream of Tartar: Tips and Tricks
Using cream of tartar is generally straightforward, but understanding the proper amounts and techniques can ensure the best results.
- For Egg Whites: Add 1/8 teaspoon of cream of tartar per egg white while whipping. This will help stabilize the foam and prevent it from collapsing.
- For Sugar Crystallization: Add 1/4 teaspoon of cream of tartar per cup of sugar. This will interfere with the formation of large sugar crystals.
- For Cleaning: Make a paste of cream of tartar and water to clean stains. Apply the paste to the stained area, let it sit for a few minutes, and then wipe it clean.
- For Laundry: Add 1/4 cup of cream of tartar to your laundry detergent. This will help brighten whites and remove dinginess.
Common Mistakes to Avoid When Using Cream of Tartar
Even though cream of tartar is a simple ingredient, it’s easy to make mistakes when using it.
- Using too much: Overusing cream of tartar can impart a slightly sour or metallic taste to baked goods. Always follow recipe instructions carefully.
- Using expired cream of tartar: Like other powdered ingredients, cream of tartar can lose its potency over time. Check the expiration date and replace it if necessary.
- Substituting with other ingredients: While there are some potential substitutes for cream of tartar, such as lemon juice or vinegar, they may not provide the same results in terms of stability and texture.
- Not storing it properly: Cream of tartar should be stored in an airtight container in a cool, dry place to prevent it from clumping or losing its effectiveness.
Cream of Tartar vs. Baking Powder: Understanding the Difference
It’s important to distinguish between cream of tartar and baking powder, as they are often confused. Baking powder is a complete leavening agent containing both an acid (typically cream of tartar) and a base (baking soda), as well as a drying agent to prevent premature reaction. Cream of tartar, on the other hand, is simply the acid component. If a recipe calls for baking powder, you cannot simply substitute cream of tartar unless you also add baking soda.
