Aquafaba. The magical, somewhat mysterious ingredient that has taken the vegan baking world by storm. Derived from the unassuming liquid leftover from cooked chickpeas, aquafaba promises to be a game-changer, especially when it comes to replicating the fluffy, ethereal texture of meringue. But does it truly live up to the hype? Can this humble byproduct actually create a stable, delicious meringue that rivals its egg-white counterpart? Let’s dive deep into the world of aquafaba meringue and uncover the secrets to its success (and potential pitfalls).
What is Aquafaba and Why All the Buzz?
Aquafaba, literally translating to “bean water,” is the starchy liquid left behind after cooking or canning legumes, most commonly chickpeas. While it might seem like mere waste at first glance, aquafaba possesses a unique combination of starches and proteins that mimic the properties of egg whites. This remarkable characteristic allows it to be whipped into stiff peaks, making it a perfect vegan substitute in recipes that traditionally rely on eggs.
The buzz around aquafaba stems from its ability to open up a whole new world of possibilities for vegan baking. Suddenly, traditionally egg-heavy recipes like meringues, macarons, mousses, and even certain cocktails become accessible to those following a plant-based diet or those with egg allergies. The excitement is palpable, and for good reason.
The Composition of Aquafaba: A Closer Look
The precise composition of aquafaba can vary depending on the type of bean used, cooking methods, and even the brand of canned chickpeas. However, it generally contains a mixture of:
- Starches: These provide structure and contribute to the stability of the whipped aquafaba.
- Proteins: These are crucial for creating the airy foam that characterizes meringue.
- Sugars: Naturally occurring sugars can influence the flavor and texture of the final product.
- Saponins: These compounds can contribute to the formation of bubbles and foam.
Understanding these components helps in troubleshooting any issues that may arise during the meringue-making process.
Why Aquafaba Works: The Science Behind the Magic
The secret to aquafaba’s meringue-making ability lies in its protein structure. When whipped, these proteins unfold and create a network that traps air bubbles. The starches then help to stabilize this network, preventing it from collapsing. It’s a similar process to what happens with egg whites, making aquafaba a surprisingly effective substitute.
The presence of saponins also aids in foam formation. These compounds act as surfactants, reducing the surface tension of the liquid and allowing for the creation of smaller, more stable bubbles.
Making Aquafaba Meringue: A Step-by-Step Guide
Creating aquafaba meringue requires a little patience and attention to detail, but the results are well worth the effort. Here’s a comprehensive guide to help you succeed:
Choosing and Preparing Your Aquafaba
The quality of your aquafaba is crucial for achieving a stable meringue. Here are some tips:
- Chickpea Aquafaba is Best: While aquafaba can be made from other beans, chickpea aquafaba generally yields the best results for meringue.
- Canned vs. Cooked from Scratch: You can use the liquid from canned chickpeas (look for low-sodium or no-salt-added varieties) or the liquid from cooking your own chickpeas.
- Reducing the Aquafaba (Optional): For a more concentrated flavor and more stable meringue, you can simmer the aquafaba over low heat until it reduces by about one-third. This will increase the protein concentration.
- Strain the Aquafaba: Strain the aquafaba through a fine-mesh sieve to remove any solids or chickpea residue.
The Whipping Process: Getting to Stiff Peaks
This is where the magic happens. Here’s how to whip your aquafaba into a meringue:
- Chill the Bowl and Beaters: Cold equipment helps the aquafaba whip up faster and more easily. Place your mixing bowl and beaters (or whisk attachment) in the freezer for about 15-20 minutes before starting.
- Start Whipping: Pour the chilled aquafaba into the chilled bowl and begin whipping on medium speed.
- Add an Acid (Cream of Tartar or Lemon Juice): Once the aquafaba starts to foam (after a few minutes), add a small amount of cream of tartar (about 1/4 teaspoon per cup of aquafaba) or lemon juice (about 1/2 teaspoon per cup). This helps to stabilize the foam and prevent it from collapsing.
- Gradually Add Sugar: With the mixer running, gradually add granulated sugar, one tablespoon at a time. This is crucial for creating a stable meringue. Allow each spoonful of sugar to fully dissolve before adding the next.
- Increase Speed to High: Once all the sugar has been added, increase the mixer speed to high and continue whipping until stiff, glossy peaks form. This can take anywhere from 5 to 15 minutes, depending on the strength of your mixer and the quality of your aquafaba.
- Test for Stiff Peaks: To test for stiff peaks, stop the mixer and lift the beater. The meringue should form a peak that stands straight up or curls over slightly at the tip. If the peak is soft and droopy, continue whipping.
Flavoring Your Aquafaba Meringue
Once you have achieved stiff peaks, you can gently fold in any desired flavorings:
- Extracts: Vanilla extract, almond extract, or other flavor extracts can be added for a subtle flavor boost.
- Citrus Zest: Lemon zest, orange zest, or lime zest can add a bright and refreshing flavor.
- Cocoa Powder: For a chocolate meringue, gently fold in sifted cocoa powder.
- Food Coloring (Optional): If you want to add color to your meringue, use gel food coloring rather than liquid food coloring, as liquid can thin out the meringue.
Baking or Using Your Aquafaba Meringue
Aquafaba meringue can be used in a variety of ways:
- Meringue Cookies: Pipe the meringue onto a baking sheet lined with parchment paper and bake at a very low temperature (around 200°F or 95°C) for several hours until dry and crisp.
- Meringue Pie Topping: Spread the meringue over a baked pie filling and bake or broil until lightly browned.
- Swiss Meringue Buttercream: Combine aquafaba meringue with butter and flavorings to create a silky smooth buttercream frosting.
- Pavlova: Spread the meringue into a circle on a baking sheet and bake until crisp on the outside and marshmallowy on the inside. Top with whipped cream and fruit.
Troubleshooting Aquafaba Meringue: Common Problems and Solutions
Even with careful attention to detail, aquafaba meringue can sometimes be tricky. Here are some common problems and how to fix them:
Meringue Doesn’t Whip Up
- Problem: The aquafaba may be too thin or weak.
- Solution: Try reducing the aquafaba by simmering it until it reduces by about one-third. Make sure your bowl and beaters are completely clean and free of grease. Adding a pinch of salt can also sometimes help.
Meringue is Too Soft or Collapses
- Problem: Not enough sugar, not enough whipping, or over-whipping.
- Solution: Make sure you are adding the sugar gradually and allowing each spoonful to fully dissolve before adding the next. Whip the meringue until stiff, glossy peaks form. Avoid over-whipping, as this can cause the meringue to become dry and crumbly.
Meringue is Sticky
- Problem: Too much humidity in the air.
- Solution: Bake the meringue on a dry day. If you live in a humid climate, you may need to bake the meringue for a longer period of time at a very low temperature to ensure it dries out completely.
Meringue Tastes Like Chickpeas
- Problem: The aquafaba was not properly prepared or the meringue was not flavored sufficiently.
- Solution: Strain the aquafaba through a fine-mesh sieve to remove any solids. Use a strong flavoring extract or citrus zest to mask any residual chickpea flavor.
Aquafaba vs. Egg White Meringue: Key Differences
While aquafaba meringue can be a great substitute for egg white meringue, there are some key differences to be aware of:
- Flavor: Aquafaba meringue may have a slight bean-like taste, especially if not properly flavored. Egg white meringue has a more neutral flavor.
- Stability: Aquafaba meringue can be slightly less stable than egg white meringue, especially in humid conditions.
- Whipping Time: Aquafaba meringue may take longer to whip to stiff peaks than egg white meringue.
- Texture: Aquafaba meringue can sometimes be slightly softer and less crisp than egg white meringue.
Despite these differences, aquafaba meringue is a viable and delicious alternative for those who cannot or choose not to consume eggs. With a little practice and attention to detail, you can create stunning vegan meringues that are sure to impress.

You might just be surprised at how well it works.
What exactly is aquafaba, and where does it come from?
Aquafaba is the viscous liquid that results from cooking legumes, most commonly chickpeas. It’s essentially the water left over after cooking chickpeas, whether you’ve cooked them yourself from dried beans or drained a can of chickpeas from the store. This liquid contains starches, proteins, and other soluble plant solids that have leached out of the chickpeas during the cooking process.
The unique properties of aquafaba, particularly its ability to whip into stiff peaks, stem from its composition of plant-based proteins and starches. These components mimic the properties of egg whites, allowing it to be used as a vegan alternative in recipes that traditionally rely on eggs for structure and texture. This discovery has been a game-changer for vegan bakers, as it opens up possibilities for creating egg-free meringues, macarons, and other delicate desserts.
Why is aquafaba a good substitute for egg whites in meringues?
Aquafaba possesses a unique combination of proteins and starches that, when whipped, can trap air and create a stable foam structure, much like egg whites. The proteins in aquafaba denature (unfold) during whipping and form a network that encapsulates air bubbles, creating the light and airy texture characteristic of meringues. This process is further stabilized by the presence of starches, which help to solidify the foam and prevent it from collapsing.
Unlike some other vegan egg substitutes, aquafaba has a relatively neutral flavor, which allows the other ingredients in the meringue, such as sugar and flavorings, to shine through. Its ability to create a stable and flavorful meringue makes it an ideal ingredient for those seeking a plant-based alternative to traditional egg-white meringues. The result is a delicate, sweet treat that is indistinguishable from its non-vegan counterpart.
What are some tips for successfully making aquafaba meringue?
For the best results, ensure your aquafaba is properly reduced. This means simmering the liquid until it reaches a slightly thicker consistency, similar to egg whites. Reducing the aquafaba concentrates the proteins and starches, leading to a more stable and voluminous meringue. It is also crucial to use an electric mixer and whip the aquafaba for a sufficient amount of time, typically around 8-10 minutes, to achieve stiff peaks.
Another crucial tip is to add sugar gradually, once the aquafaba has started to form soft peaks. Adding the sugar too early can inhibit the aquafaba’s ability to whip properly. It’s also important to use a stabilizer such as cream of tartar or lemon juice. These stabilizers help to lower the pH of the aquafaba, which in turn helps to create a more stable meringue that holds its shape better during baking.
Can I use aquafaba from any type of bean or legume?
While aquafaba can technically be derived from various legumes, chickpea aquafaba is the most widely used and reliably successful for meringue making. Chickpea aquafaba generally has a more neutral flavor and a higher protein content compared to other bean varieties, which contribute to its superior whipping properties. Other beans might produce aquafaba, but it may be less stable or have a stronger, less desirable flavor.
Experimenting with aquafaba from other beans like white beans or cannellini beans might be possible, but it’s important to consider that the results could vary significantly. The consistency, taste, and whipping ability might not be as consistent or predictable as with chickpea aquafaba. If you choose to experiment, be sure to taste the aquafaba before using it and adjust the sugar and flavorings in your recipe accordingly.
How does aquafaba meringue compare to traditional egg-white meringue in terms of taste and texture?
When properly made, aquafaba meringue boasts a remarkably similar taste and texture to traditional egg-white meringue. The texture is light, airy, and slightly chewy, with a crisp exterior. The taste is subtly sweet and can be easily flavored with extracts, citrus zest, or other ingredients. Many people find it difficult to distinguish between aquafaba meringue and egg-white meringue in a blind taste test.
However, slight differences can arise. Some may perceive a very faint “beany” aftertaste in aquafaba meringue, especially if the aquafaba wasn’t properly reduced or if the recipe doesn’t include strong flavorings. Additionally, aquafaba meringue can sometimes be slightly more delicate and prone to weeping (releasing liquid) if not baked or stored correctly. Despite these minor differences, aquafaba meringue is a very close and often indistinguishable alternative to traditional meringue.
What are some creative ways to use aquafaba meringue?
Beyond classic meringue cookies, aquafaba meringue opens up a world of possibilities in vegan baking and dessert making. You can use it to create light and fluffy vegan pavlovas, topping them with fresh fruit and vegan whipped cream. It also works beautifully as a frosting for cakes and cupcakes, providing a sweet and airy alternative to buttercream.
Aquafaba meringue can also be used in mousses, puddings, and even cocktails to add texture and lightness. For example, a vegan chocolate mousse can be made exceptionally light and airy by folding in whipped aquafaba meringue. Similarly, it can be used to create a frothy topping for vegan cocktails, adding a touch of elegance and visual appeal. Its versatility makes it a valuable ingredient in any vegan kitchen.
How should aquafaba meringue be stored to maintain its texture and prevent weeping?
Proper storage is crucial for maintaining the quality of aquafaba meringue. Baked meringues should be stored in an airtight container at room temperature. This prevents them from absorbing moisture from the air, which can cause them to become sticky or lose their crispness. Adding a desiccant like uncooked rice or silica gel packets to the container can further help to absorb any excess moisture.
Unbaked aquafaba meringue, such as meringue frosting or pavlova shells, is best used immediately or stored in the refrigerator for a short period. Refrigeration can sometimes cause the meringue to weep, but this can be minimized by ensuring the meringue is thoroughly baked and cooled before refrigerating. If weeping does occur, you can try gently patting the surface with a paper towel before serving. However, it’s generally recommended to use aquafaba meringue as soon as possible after it’s made for the best texture and appearance.
