Aquafaba, the magical liquid leftover from cooking legumes, has revolutionized vegan baking and cooking. Its ability to mimic egg whites has opened up a world of culinary possibilities. But the question remains: can you get aquafaba from other beans besides chickpeas? The short answer is yes, but the long answer involves a more nuanced understanding of bean composition, cooking methods, and desired applications.
Understanding Aquafaba’s Magic
Aquafaba isn’t just bean water. It’s a complex mixture of starches, proteins, and soluble solids that leach out of the beans during cooking. These components, particularly the proteins, are what give aquafaba its unique whipping and emulsifying properties. The quality and characteristics of aquafaba vary depending on the type of bean used, the cooking process, and the bean-to-water ratio.
The protein content is the key to aquafaba’s emulsifying and foaming properties. When whisked, these proteins unfold and create a stable network that traps air, resulting in the light and airy textures we see in meringues, mousses, and vegan mayonnaise. The starches contribute to viscosity and stability, helping to prevent the foam from collapsing.
Factors Influencing Aquafaba Quality
Several factors determine the success of using different beans for aquafaba. These include:
- Bean Type: Different beans have varying protein and starch compositions. Chickpeas are particularly high in protein, which contributes to their superior aquafaba quality.
- Cooking Method: Slow cooking methods, like simmering, tend to extract more solids and proteins from the beans compared to pressure cooking.
- Bean-to-Water Ratio: Using a higher ratio of beans to water during cooking will result in a more concentrated aquafaba.
- Salt Content: Adding a small amount of salt during cooking can improve the flavor of the aquafaba and may also influence its whipping properties.
- Bean Age: Older beans may yield less desirable aquafaba due to the breakdown of starches and proteins over time.
- Post-Cooking Reduction: Reducing the liquid after cooking can concentrate the aquafaba, enhancing its thickening and emulsifying capabilities.
Exploring Alternative Bean Aquafabas
While chickpea aquafaba remains the gold standard, experimenting with other beans can yield interesting results. Here’s a look at some alternatives and their potential:
White Bean Aquafaba (Navy, Great Northern, Cannellini)
White beans, such as navy beans, Great Northern beans, and cannellini beans, are often considered the next best alternative to chickpeas. They generally produce a lighter-colored aquafaba with a milder flavor, making them versatile for both sweet and savory applications. Navy bean aquafaba is particularly popular due to its neutral taste.
The process for making aquafaba from white beans is similar to that of chickpeas:
- Soak dried beans overnight.
- Drain and rinse the beans.
- Cook the beans in ample water until tender.
- Drain the beans, reserving the cooking liquid (aquafaba).
- Reduce the aquafaba on the stovetop if necessary to achieve a thicker consistency.
White bean aquafaba can be used in recipes calling for chickpea aquafaba, often with similar results. However, it may require slightly longer whipping times to achieve the same volume.
Black Bean Aquafaba
Black bean aquafaba is another viable option, but it comes with a caveat: its dark color. This can significantly affect the appearance of your final dish, particularly in light-colored recipes like meringues. However, in applications where color isn’t a concern, such as chocolate desserts or savory sauces, black bean aquafaba can be a suitable substitute.
The flavor of black bean aquafaba is slightly more pronounced than chickpea or white bean aquafaba, so it’s important to consider how it will complement the other ingredients in your recipe.
To minimize the color impact, some cooks suggest using a coffee filter to further clarify the aquafaba after cooking. This can help remove some of the darker pigments and create a lighter-colored liquid.
Soybean Aquafaba
Soybean aquafaba presents unique challenges and opportunities. Soybeans are high in protein, which should theoretically make them ideal for aquafaba production. However, the flavor of soybean aquafaba can be quite strong and beany, making it less versatile than chickpea or white bean aquafaba.
Furthermore, soybeans contain compounds that can interfere with protein foaming. To overcome this, some recipes recommend adding a small amount of acid, such as lemon juice or cream of tartar, to the aquafaba before whipping. This can help stabilize the foam and improve its volume.
Soybean aquafaba is best suited for applications where the strong flavor can be masked or complemented by other ingredients, such as in savory sauces or fermented foods.
Other Bean Aquafabas (Kidney, Pinto, etc.)
While less common, it is possible to create aquafaba from other beans like kidney beans, pinto beans, and lentils. However, the results are often less predictable and the flavor profiles can be quite strong. These aquafabas may also require longer cooking times and more significant reduction to achieve the desired consistency.
Generally, the darker the bean, the more pronounced the flavor of the resulting aquafaba. It’s crucial to taste the aquafaba before using it in a recipe to ensure that the flavor is acceptable. Experimentation is key to finding the right applications for these less common bean aquafabas.
Tips for Successful Alternative Aquafaba Production
Regardless of the bean you choose, here are some tips to maximize your chances of success:
- Use High-Quality Beans: Start with fresh, high-quality beans for the best results. Avoid using old or damaged beans.
- Soak Beans Thoroughly: Soaking beans overnight helps to soften them and reduce cooking time. It also leaches out some of the indigestible sugars that can cause gas.
- Control the Water Ratio: Use a higher ratio of beans to water to create a more concentrated aquafaba. Start with a ratio of 1 part beans to 2 parts water and adjust as needed.
- Simmer Gently: Avoid boiling the beans vigorously, as this can damage the proteins and reduce the aquafaba’s whipping ability. Simmer the beans gently over low heat.
- Reduce the Liquid: After cooking the beans, reduce the aquafaba on the stovetop until it reaches the consistency of egg whites. This will concentrate the proteins and starches, improving its whipping properties.
- Chill Thoroughly: Allow the aquafaba to cool completely before using it. Chilling helps to stabilize the proteins and improves the foam’s volume and stability.
- Add an Acid: Adding a small amount of acid, such as lemon juice or cream of tartar, can help to stabilize the foam and improve its volume.
- Taste and Adjust: Always taste the aquafaba before using it in a recipe and adjust the seasoning as needed.
- Strain if Needed: If your aquafaba has a lot of debris, strain it through a fine-mesh sieve or cheesecloth to remove any solids.
Applications Beyond Meringues
While aquafaba is famously used in meringues, its versatility extends far beyond that. Here are some other applications for this magical liquid:
- Vegan Mayonnaise: Aquafaba can be used as an emulsifier to create rich and creamy vegan mayonnaise.
- Mousses and Desserts: It provides the light and airy texture in vegan mousses, cakes, and other desserts.
- Baked Goods: It acts as an egg replacer in cookies, muffins, and breads.
- Cocktails: It creates a frothy texture in cocktails, similar to egg whites.
- Waffles and Pancakes: It adds lightness and fluffiness to waffles and pancakes.
- Buttercream Frosting: Aquafaba-based buttercream is a surprisingly delicious and stable vegan frosting option.

The future of aquafaba is bright, with ongoing research and development focused on optimizing its properties and expanding its use in a wide range of culinary applications.
While chickpea aquafaba remains the most reliable and widely used option, exploring aquafaba from other beans can be a rewarding culinary adventure. By understanding the factors that influence aquafaba quality and experimenting with different beans, you can unlock a world of flavor and texture possibilities.
What other types of beans besides chickpeas can be used to make aquafaba?
While chickpea aquafaba is the most well-known and widely used, other beans, such as white beans (cannellini, navy, Great Northern), black beans, and even soybeans, can also produce aquafaba. The key factor is the protein and starch content of the beans, which leach into the water during cooking. These compounds contribute to the foaming and emulsifying properties needed for successful aquafaba.
However, it’s important to note that the results can vary. Different beans produce aquafaba with slightly different characteristics, such as flavor, color, and stability. Experimentation is often necessary to find which bean aquafaba works best for a particular recipe. Factors like bean variety, cooking time, and water hardness can all impact the final product.
How does the flavor of aquafaba differ depending on the type of bean used?
The flavor of aquafaba can indeed vary based on the type of bean used. Chickpea aquafaba is typically considered to have a relatively neutral flavor, making it suitable for a wide range of sweet and savory applications. Aquafaba from white beans like cannellini or navy beans also tends to be mild, but might possess a slightly more distinct “beany” note.
Darker beans like black beans will impart a more noticeable flavor and color to the aquafaba. This can be advantageous in dishes where a subtle bean flavor complements the other ingredients, such as chocolate desserts or sauces. However, it might be less desirable in recipes where a neutral flavor is essential, like meringues.
Are there any specific preparation steps required when using aquafaba from beans other than chickpeas?
The basic preparation steps for aquafaba remain similar regardless of the bean used. You can either use the liquid from canned beans (preferably low-sodium or no-salt-added) or cook dried beans yourself. When cooking dried beans, use plenty of water and avoid adding salt, as this can interfere with the foaming properties.
After cooking (or opening the can), allow the liquid to cool slightly. It’s often beneficial to reduce the aquafaba by simmering it gently on the stovetop. This concentrates the proteins and starches, resulting in a more stable and effective foaming agent. The degree of reduction might vary depending on the type of bean and desired consistency.
What are the best uses for aquafaba derived from different types of beans?
Chickpea aquafaba remains a versatile choice for many applications, including meringues, mousses, mayonnaise, and vegan baking. White bean aquafaba, due to its milder flavor, is also well-suited for these general uses, particularly in recipes where you want to avoid any prominent bean taste.
Black bean aquafaba, with its more distinct flavor profile, is best used in chocolate-based desserts, brownies, sauces, or dips where the subtle bean flavor complements the overall taste. Soy bean aquafaba can have a stronger, more noticeable taste and may be best suited for savory dishes, sauces, or as an egg replacement in some recipes after careful flavoring and recipe adjustment.
Does the protein content of aquafaba vary significantly across different bean types?
Yes, the protein content of aquafaba does vary depending on the type of bean used, which directly impacts its foaming and emulsifying abilities. Chickpea aquafaba typically has a relatively consistent protein concentration, contributing to its reliable performance in various recipes. White beans tend to have a slightly lower protein content in their aquafaba compared to chickpeas.
Black beans and soybeans generally have a higher protein content than chickpeas or white beans. This higher protein concentration can lead to a more stable and voluminous foam, making them potentially suitable for applications requiring strong aeration. However, the stronger flavor profile might need to be considered when using these types of aquafaba.
Are there any specific challenges or considerations when working with aquafaba from less common beans?
One of the main challenges with using aquafaba from less common beans is the inconsistent results. The quality of the aquafaba can vary depending on the specific bean variety, cooking conditions, and storage methods. Therefore, careful experimentation and adjustment of recipes may be required to achieve the desired outcome.
Another consideration is the potential for stronger or more noticeable flavors. Unlike chickpea aquafaba, which is generally neutral, aquafaba from beans like black beans or soybeans can impart a distinct flavor to the final product. This needs to be carefully considered when selecting a bean for a particular recipe and may necessitate adjustments to flavorings and other ingredients.
How can I adjust my recipes to account for the varying characteristics of aquafaba from different beans?
When adapting recipes to use aquafaba from different beans, begin by considering the flavor profile. If using a bean with a stronger flavor, such as black beans, you may need to adjust the amount of other flavorings in the recipe to balance the taste. Consider adding complementary flavors like chocolate, coffee, or spices.
Also, pay attention to the viscosity and foaming ability of the aquafaba. If the aquafaba seems thin or doesn’t whip as well as chickpea aquafaba, try reducing it further on the stovetop to concentrate the proteins. You might also need to adjust the whipping time or add a stabilizer, such as cream of tartar, to help the foam hold its shape. Thorough testing is crucial to ensure the desired texture and stability in the final product.
