What is Cream of Tartar?
Cream of tartar, chemically known as potassium bitartrate, is an acidic salt that is a byproduct of winemaking [1]. It's a fine white powder widely used in the culinary world for its unique properties.
Common Culinary Uses
Cream of tartar has several practical applications in the kitchen:
- Stabilizing Egg Whites: It helps to stabilize whipped egg whites, increasing their volume and heat tolerance, which is essential for meringues and soufflés [3].
- Preventing Sugar Crystallization: In candy making and syrup production, a pinch of cream of tartar can prevent sugar from forming crystals, resulting in a smoother texture [3].
- Activating Baking Soda: As an acid, it reacts with alkaline baking soda to produce carbon dioxide gas, which helps baked goods rise when heat is applied [3].
These uses involve small quantities of cream of tartar, incorporated into larger recipes.
Why Direct Consumption of Large Amounts is Not Recommended
While safe for its intended use in cooking, consuming cream of tartar directly in large amounts is strongly discouraged [2]. It is important to understand that food ingredients designed for specific culinary purposes are not always meant for direct ingestion in significant quantities.
Comparison: Culinary Use vs. Direct Ingestion
It's helpful to see the difference between using cream of tartar as intended and consuming it directly:
| Aspect | Culinary Use (Small Amounts in Recipes) | Direct Ingestion (Large, Undiluted Amounts) | 
|---|---|---|
| Purpose | Ingredient to aid in baking/cooking processes [3]. | Not an intended use; potentially for unverified purposes [2]. | 
| Quantity | Typically teaspoons or less within a full dish [1]. | Potentially multiple tablespoons or more [2]. | 
| Context | Integrated into a recipe with other ingredients [1]. | Consumed on its own, sometimes with liquid [2]. | 
| Recommendation | Standard and safe culinary practice [1]. | Not recommended and potentially problematic [2]. | 
Conclusion: Use as Intended
Cream of tartar is a valuable tool in the kitchen when used correctly in recipes. Its properties make it useful for stabilizing, leavening, and preventing crystallization. However, it is not intended for direct consumption in large amounts. Always use cream of tartar as directed in recipes and store it safely away from direct access.
