Royal icing, with its smooth, porcelain-like finish, is the go-to choice for decorating cookies, cakes, and gingerbread houses. Its versatility allows for intricate designs, sharp lines, and a delightful, edible art form. Meringue powder is a popular ingredient, prized for its stability and convenience in creating royal icing. However, what if you’re out of meringue powder, have dietary restrictions, or simply prefer a different approach? Fear not! There are several excellent substitutes you can use to achieve that perfect royal icing consistency and finish. This article explores various alternatives to meringue powder, offering detailed guidance and tips for successful royal icing creation.
Understanding Meringue Powder’s Role in Royal Icing
Before diving into alternatives, it’s essential to understand why meringue powder is so valued in royal icing recipes. Meringue powder primarily functions as a stabilizer and binder. It contains dried egg whites, cornstarch, and sometimes sugar and gums. The dried egg whites provide the necessary protein structure for the icing to set firm and hold its shape. The cornstarch helps prevent the icing from becoming too runny and contributes to its smooth texture. The addition of gums can further enhance the icing’s stability and prevent cracking. By understanding these roles, you can better choose a suitable substitute.
Fresh Egg Whites: The Classic Alternative
The most traditional substitute for meringue powder is fresh egg whites. They offer the purest form of protein and contribute to a superior flavor. Using fresh egg whites requires caution, as raw egg whites can carry the risk of salmonella. However, when properly pasteurized or when using a recipe that heats the egg whites, the risk is minimized.
Pasteurizing Egg Whites at Home
Pasteurizing egg whites at home involves gently heating them to a specific temperature to kill any harmful bacteria. To do this, combine egg whites and sugar in a heatproof bowl. Place the bowl over a saucepan of simmering water, ensuring the bowl doesn’t touch the water. Continuously stir the mixture with a whisk until it reaches 160°F (71°C) on a candy thermometer. Remove from heat and proceed with your royal icing recipe.
Recipes Using Fresh Egg Whites
Royal icing made with fresh egg whites often has a superior taste and a slightly glossier finish. A typical recipe includes:
- 2 large egg whites
- 4 cups (approximately 1 pound) powdered sugar
- 2 teaspoons lemon juice or vanilla extract
Beat the egg whites until they form soft peaks. Gradually add the powdered sugar, beating until the icing reaches the desired consistency. Stir in the lemon juice or vanilla extract.
Pros and Cons of Using Fresh Egg Whites
Pros:
- Enhanced flavor.
- Traditional approach.

Considerations for Choosing a Substitute
When selecting a meringue powder substitute, consider your dietary needs, desired flavor profile, and the level of stability you require for your project. If you’re looking for the closest flavor to meringue powder, fresh egg whites or liquid egg whites are good choices. For vegan options, aquafaba provides a reliable alternative. If stability is your primary concern, gelatin can be a helpful addition, but remember it’s not suitable for all diets. Cornstarch can help thicken icing, while cream of tartar enhances the performance of egg whites or aquafaba.
Tips for Perfect Royal Icing Consistency
Regardless of the substitute you choose, achieving the perfect royal icing consistency is crucial for successful decorating. Royal icing is typically made in three consistencies: outlining, flooding, and detail work.
- Outlining Consistency: This is the thickest consistency, used for creating borders and preventing the flooding icing from running off the edge of the cookie. It should hold its shape well.
- Flooding Consistency: This is a thinner consistency used to fill in the outlined areas. It should flow smoothly and evenly, creating a smooth surface.
- Detail Consistency: This consistency falls somewhere between outlining and flooding, suitable for adding fine details and intricate designs.
To adjust the consistency of your royal icing, add small amounts of water or powdered sugar until you reach the desired thickness. Use a spray bottle for water to avoid adding too much liquid at once.
Troubleshooting Common Royal Icing Problems
Even with the best substitutes and techniques, you might encounter some common problems when working with royal icing.
- Icing is too thick: Add water, a few drops at a time, until you reach the desired consistency.
- Icing is too thin: Add powdered sugar, a tablespoon at a time, until it thickens.
- Icing is cracking: This is often caused by the icing drying out too quickly. Try adding a small amount of glycerin or shortening to the recipe.
- Icing is grainy: This can be caused by using too much cornstarch or by the powdered sugar not being finely ground enough. Sift the powdered sugar before using it.
- Icing is not setting: Ensure you are using enough of the substitute to provide the necessary structure and stability. You may need to adjust the recipe or try a different substitute.
Conclusion
While meringue powder offers convenience and stability, it’s not the only option for creating beautiful and delicious royal icing. Fresh egg whites, liquid egg whites, aquafaba, gelatin, cornstarch, and cream of tartar all offer viable alternatives, each with its own unique properties and benefits. By understanding the role of meringue powder and carefully adjusting your recipes, you can create stunning royal icing creations using the substitute that best suits your needs and preferences.

What is the primary function of meringue powder in royal icing?
Meringue powder serves several crucial roles in royal icing. Primarily, it acts as a stabilizer, helping to create a strong, stable structure that hardens properly and prevents the icing from becoming too thin or runny. It provides the necessary proteins to form stiff peaks and hold the intricate shapes required for decorating cookies and cakes.
In addition to stabilization, meringue powder contributes to the icing’s overall texture and volume. It enhances the icing’s ability to dry to a smooth, matte finish, which is aesthetically pleasing. Furthermore, it improves the icing’s ability to hold its shape, making it ideal for detailed piping work and creating intricate designs.
Can I use fresh egg whites instead of meringue powder in royal icing?
Yes, fresh egg whites can be used as a substitute for meringue powder in royal icing. Using fresh egg whites often results in a slightly softer, more flavorful icing compared to icing made with meringue powder. Ensure the eggs are pasteurized to eliminate the risk of salmonella. Approximately one large egg white can replace one tablespoon of meringue powder.
However, using fresh egg whites does present some challenges. The quality of the egg whites can vary, affecting the consistency and stability of the icing. It is critical to carefully separate the yolks from the whites and avoid any trace of yolk contamination, as this can prevent the whites from whipping properly and achieving the desired stiff peaks. Additionally, the resulting icing has a shorter shelf life and requires refrigeration.
Is aquafaba a suitable vegan alternative to meringue powder in royal icing?
Aquafaba, the liquid from canned chickpeas, is indeed a suitable vegan alternative to meringue powder. It possesses similar protein properties that allow it to whip up into stable foams, mimicking the stabilizing effect of meringue powder in royal icing. Aquafaba provides a plant-based option for achieving the desired consistency and structure for intricate designs.
While aquafaba offers a fantastic vegan solution, it’s essential to note that it can sometimes impart a slight bean-like flavor. Adding a touch of vanilla extract or lemon juice can effectively mask this flavor. Experimentation may be required to adjust the liquid-to-sugar ratio, as aquafaba can sometimes result in a slightly softer icing compared to meringue powder. However, with the right adjustments, you can create beautiful and intricate royal icing designs.
How does using gelatin as a substitute for meringue powder impact royal icing?
Gelatin can be used as a substitute for meringue powder, particularly for those seeking a very stable and durable royal icing. It provides a strong structure and helps the icing to set firmly, which can be beneficial for intricate designs that require a lot of support. Typically, a very small amount of unflavored gelatin, bloomed in water, is added to the royal icing.
However, using gelatin alters the texture and working properties of the icing. The icing can become quite stiff and less pliable, potentially making it more difficult to pipe intricate details. Also, gelatin is not suitable for vegetarian or vegan diets. It’s important to be precise with measurements and avoid overusing gelatin, as it can lead to a gummy texture. Using a small amount is key to improving stability without sacrificing workability.
Can cornstarch replace meringue powder in royal icing?
Cornstarch is not a direct replacement for meringue powder. Meringue powder provides protein for stability and structure, while cornstarch is primarily a thickening agent. While cornstarch can thicken royal icing, it doesn’t offer the same structural support or aid in achieving the stiff peaks needed for intricate designs.
If you’re using cornstarch, it’s best used in conjunction with other ingredients that provide stability, such as egg whites or a small amount of gelatin. Adding cornstarch alone can result in a brittle icing that cracks easily and doesn’t hold its shape well. It is only suitable to slightly thicken icing that has already been stabilized by another component.
How does using cream of tartar affect royal icing when substituting for meringue powder?
Cream of tartar is not a direct substitute for meringue powder, but it can be used as an additive to improve the stability of royal icing, particularly when using fresh egg whites. It helps to stabilize the egg whites and create a more voluminous and stable meringue, which in turn results in a firmer royal icing.
Cream of tartar works by increasing the acidity of the egg whites, allowing them to whip up to a greater volume and hold their shape better. It helps prevent the egg whites from collapsing and creates a smoother, more consistent icing. However, it does not offer the same overall benefits as meringue powder, which also adds volume and texture. When using cream of tartar, it’s essential to still use a stabilizer like fresh egg whites or aquafaba.
What considerations should I make when adjusting a recipe to use a meringue powder alternative?
When substituting meringue powder in a royal icing recipe, it’s important to consider the liquid content of your chosen alternative. Fresh egg whites and aquafaba, for example, will add more liquid to the recipe than meringue powder, so you may need to reduce the amount of liquid initially added to compensate. Monitor the consistency carefully as you mix and adjust as needed to achieve the desired piping consistency.
Furthermore, be aware of any flavor changes that may result from the substitution. Alternatives like aquafaba can sometimes impart a subtle flavor, which can be masked with extracts or other flavorings. Always taste the icing and adjust the flavor profile to your preference. Finally, be prepared to experiment with the ratios and techniques to find what works best for your particular recipe and desired outcome. Each alternative behaves slightly differently and requires adjustments to achieve the optimal result.
