Where Would You Find Cream of Tartar?
Cream of tartar is commonly found in the baking aisle of most grocery stores, often near the spices, baking powder, and baking soda. It can also be found online from various retailers and specialty baking supply shops.
Introduction: Unlocking the Secrets of Cream of Tartar
Cream of tartar, also known as potassium bitartrate, is a powdery acidic byproduct of winemaking. While it might sound exotic, it’s actually a staple ingredient in many kitchens and baking recipes. Understanding its origins and uses can elevate your culinary creations and provide insights into its versatility. It is an important ingredient with a long shelf life.
Background: From Wine Barrels to Baking Sheets
The journey of cream of tartar begins in wine barrels. As wine ferments, tartaric acid naturally crystallizes and adheres to the sides of the barrels. These crystals are then scraped off, purified, and ground into the fine white powder we know as cream of tartar. This natural origin makes it a unique and appealing ingredient for those seeking less processed food options.
Baking Benefits: Enhancing Textures and Stability
Cream of tartar plays several crucial roles in baking:
- Stabilizing Egg Whites: It helps prevent egg whites from collapsing, creating stiff and glossy meringues, soufflés, and angel food cakes.
- Preventing Sugar Crystallization: In candies and syrups, it inhibits the formation of unwanted sugar crystals, resulting in a smoother texture.
- Activating Baking Soda: When combined with baking soda, it acts as a leavening agent, producing a light and airy texture in baked goods.
- Enhancing Flavor: It adds a slightly tangy note that complements the sweetness of many desserts.
Beyond Baking: Unexpected Uses for Cream of Tartar
The utility of cream of tartar extends beyond the realm of baking.
- Cleaning Copper and Brass: Its mild acidity makes it an effective and natural cleaner for tarnished metals.
- Household Cleaner: Mixed with vinegar and baking soda, it becomes an effective scrub for grimy surfaces.
- Homemade Playdough: It contributes to the elasticity and texture of homemade playdough, making it smoother and less sticky.
- Skin Exfoliation: Though less common, some use a paste of cream of tartar and water as a gentle facial exfoliant. Use caution, and test on a small area first.
Identifying Cream of Tartar: What to Look For
Cream of tartar is typically sold in small jars or packets. Look for these characteristics to ensure you’re buying the correct product:
- Appearance: A fine, white, odorless powder.
- Packaging: Clearly labeled as “cream of tartar” or “potassium bitartrate.”
- Expiration Date: Check the expiration date to ensure freshness, although it has a very long shelf life.
- Ingredients: The ingredient list should ideally contain only potassium bitartrate.
Storage: Maximizing Shelf Life
To keep cream of tartar fresh and effective, store it in an airtight container in a cool, dry place away from direct sunlight. Proper storage can significantly extend its already long shelf life, potentially for years beyond the expiration date.
Common Mistakes: Avoiding Baking Disasters
While generally forgiving, improper use of cream of tartar can lead to baking mishaps:
- Using Too Much: An excess of cream of tartar can impart a metallic or sour taste to your baked goods.
- Using Expired Cream of Tartar: While it doesn’t necessarily “go bad,” its leavening power might diminish over time, resulting in flat or dense baked goods.
- Substituting Incorrectly: Cream of tartar is not a direct substitute for baking powder or baking soda, although it works in conjunction with baking soda.
Cream of Tartar Substitutes: When You’re in a Pinch
If you find yourself without cream of tartar, consider these substitutes:
| Substitute | Ratio | Notes |
|---|---|---|
| Lemon Juice | 2 teaspoons lemon juice for 1 teaspoon cream of tartar | May slightly alter the flavor profile. |
| White Vinegar | 2 teaspoons white vinegar for 1 teaspoon cream of tartar | Similar to lemon juice, may subtly affect the taste. |
| Baking Powder | Not recommended as a direct substitute. | Baking powder already contains cream of tartar (acid) and baking soda (base). |
Frequently Asked Questions (FAQs)
H4: What is the chemical composition of cream of tartar?
Cream of tartar is chemically known as potassium bitartrate or potassium hydrogen tartrate, represented by the chemical formula KC₄H₅O₆. This indicates that it is the monopotassium salt of tartaric acid.
H4: Can I make cream of tartar at home?
While it’s technically possible to extract potassium bitartrate from winemaking byproducts, it’s a complex and time-consuming process best left to professionals. Buying it is much easier.
H4: Is cream of tartar gluten-free?
Yes, cream of tartar is naturally gluten-free. It is derived from grapes and does not contain any gluten-containing ingredients. However, always check the packaging to ensure there has been no cross-contamination during processing.
H4: Does cream of tartar expire?
While cream of tartar doesn’t truly expire in the sense of becoming unsafe to eat, its leavening power can diminish over time. Check the expiration date and consider using a fresh batch for best results, especially in recipes requiring precise leavening.
H4: Is cream of tartar the same as tartar sauce?
No, cream of tartar and tartar sauce are completely different. Cream of tartar is a dry, acidic powder used in baking, while tartar sauce is a creamy condiment typically made with mayonnaise, pickles, and herbs.
H4: Can I use cream of tartar in place of baking powder?
No, you cannot directly substitute cream of tartar for baking powder. Baking powder contains both an acid (cream of tartar) and a base (baking soda), while cream of tartar is only the acidic component. You can create a baking powder substitute by combining cream of tartar and baking soda, but the ratios must be precise.
H4: Is cream of tartar safe to consume?
Yes, cream of tartar is generally safe to consume in the quantities typically used in baking and cooking. However, consuming large amounts of pure cream of tartar can cause digestive upset.
H4: How does cream of tartar stabilize egg whites?
Cream of tartar stabilizes egg whites by lowering their pH. This allows the egg white proteins to denature (unfold) and form stronger bonds, creating a more stable foam that is resistant to collapse.
H4: Can I use cream of tartar to remove stains from clothes?
Yes, cream of tartar can be used to remove some stains from clothes, particularly those caused by rust or tea. Make a paste of cream of tartar and water, apply it to the stain, and let it sit for a few hours before washing. However, always test the paste on an inconspicuous area first to ensure it doesn’t damage the fabric.
H4: What are some potential health benefits of cream of tartar?
While not its primary purpose, cream of tartar contains potassium, an essential mineral. However, it’s not a significant source compared to other foods. Some believe it may help with urinary tract infections, but scientific evidence is limited.
H4: Can cream of tartar be used to treat kidney stones?
No, there is no evidence to support the use of cream of tartar for treating or preventing kidney stones. Always consult a healthcare professional for any health concerns.
H4: What are some common recipes that use cream of tartar?
Common recipes that use cream of tartar include:
- Angel food cake
- Meringues
- Snickerdoodle cookies
- Candies and syrups
- Some types of frostings
