What Is Aquafaba?
Aquafaba is the viscous liquid that results from cooking chickpeas, a type of legume popular in various global cuisines. In the context of vegan baking, it is celebrated as an effective egg substitute due to its unique properties. This translucent, slightly yellowish liquid has a consistency similar to that of raw egg whites, which makes it ideal for a range of culinary applications.
The name 'aquafaba' is derived from two Latin words: 'aqua' (water) and 'faba' (bean). When chickpeas are cooked, they release proteins and starches into the water, transforming it into aquafaba. The composition of aquafaba allows it to be whipped into a foam, much like egg whites, and it can maintain this foamy texture, which is crucial for the structure in many baked goods.
Despite its unassuming appearance, aquafaba's ability to perform in recipes is remarkable. It not only binds ingredients together but also provides the necessary 'lift' in recipes such as meringues, mousses, and macarons. For those with allergies to eggs, it serves as a safe and effective alternative. Additionally, it contains no animal products, aligning perfectly with a vegan lifestyle.
Aquafaba can be obtained two ways: either from the liquid of canned chickpeas or from the water in which home-cooked chickpeas have been boiled. Its versatility is not limited to baking; it can also be used in savory dishes, offering a plant-based protein source without altering the flavor.
Here is a brief overview of its properties:
Origin: Liquid from cooked chickpeas
Uses: Baking, cooking, whipping into foam
Benefits: Vegan, allergen-friendly, multipurpose
Consistency: Similar to egg whites, can be whipped to form stiff peaks
Due to these qualities, aquafaba stands out as a culinary marvel in plant-based diets, embodying the ingenuity of vegan cooking solutions.
The Science Behind Aquafaba
Aquafaba, the viscous liquid from cooked chickpeas, has emerged as a remarkable egg substitute due to its unique composition. Its ability to emulate egg whites' structural qualities in recipes is attributed to a specific blend of proteins, starches, and other plant compounds.
Protein and Starch Composition
Aquafaba is abundant in both proteins and starches, which are leached from chickpeas during the cooking process. The proteins, which include albumins and globulins, are crucial for structure and stability, providing the necessary building blocks that allow aquafaba to mimic the binding and emulsifying properties of egg whites. Starches in aquafaba contribute to its viscosity and are essential in aiding the retention of gas bubbles within the matrix, ensuring a stable foam is formed.
Saponins and Foaming Properties
Saponins, naturally occurring compounds found in various plant-based sources including chickpeas, greatly influence the foaming properties of aquafaba. They act as surfactants, which reduce the surface tension of the bean liquid, allowing it to trap air more effectively and create foam. This characteristic is vital for producing the light and airy texture desired in baked goods such as meringues and mousses.
How Cooking and Reduction Affect Aquafaba
The manner in which chickpeas are cooked and the aquafaba is reduced plays a significant role in the functionality of this egg substitute. Simmering chickpeas releases more proteins and starches into the water, enhancing the structural qualities of the aquafaba. Furthermore, reducing the liquid by simmering it post-straining can concentrate these valuable components, thereby improving stability and whip-ability. The consistency of aquafaba can vary, but a reduced, slightly thicker consistency is often likened to that of raw egg whites, indicating its enhanced efficacy in recipes.
Preparing Homemade Aquafaba
Aquafaba, the liquid from cooked chickpeas, serves as an exceptional egg substitute in vegan baking. It can be prepared using either canned chickpeas for convenience or dried chickpeas for those who prefer a from-scratch approach.
Using Canned Chickpeas
To use canned chickpeas, begin by draining the liquid from the can into a bowl. It is essential to rinse the chickpeas thoroughly to remove any preservatives or sodium. The drained aquafaba is ready to use and can be frozen for long-term storage or kept in the refrigerator for a few days.
From Dry Chickpeas: Step-By-Step
For those preferring homemade aquafaba from dried chickpeas, the following steps are a guide:
Rinse the dried chickpeas to remove any debris.
Cover them with water and allow to soak overnight, which helps in softening them.
After soaking, drain and rinse the chickpeas again, then transfer them to a saucepan or pot.
Add fresh water — approximately 3 cups of water for every cup of soaked chickpeas.
Bring the mixture to a boil over high heat on the stove, then lower the heat and simmer until the chickpeas are tender, typically for 60-75 minutes.
Straining and Consistency Adjustments
Once the chickpeas are cooked:
Use a strainer to separate the solid chickpeas from the liquid. The resulting aquafaba should have a viscous consistency similar to that of raw egg whites.
If the aquafaba appears too watery, it can be reduced over low heat to thicken it.
Conversely, if it is too thick, adding a little water can achieve the desired consistency.
By following these steps, one can prepare aquafaba that is well-suited for vegan baking endeavours, with the correct texture and binding properties to replicate eggs.
Whipping Aquafaba into Meringue
Aquafaba meringue acts as a remarkable substitute for egg whites, providing a vegan solution for achieving voluminous and light meringue peaks. Mastery in working with this liquid ensures a stable and glossy finish ideal for a multitude of vegan baking applications.
Achieving the Right Foaminess
To start, one must drain chickpeas to collect the aquafaba liquid, which is the basis for the meringue. The key to foaming lies in the use of a stand mixer or hand mixer; attempting to whip aquafaba manually is not recommended as it can be extremely labor-intensive and often does not yield the desired results. For ideal foaminess, the liquid should be whisked on a medium speed until frothy, which usually takes about 1 to 2 minutes.
Tool Essentials:
Stand mixer or hand mixer (recommended for even results)
Mixing bowl
Adding Cream of Tartar for Stabilization
Cream of tartar, a byproduct of wine making, is crucial when stabilizing whipped aquafaba, enhancing both its structure and shelf life. A common ratio is 1/8 teaspoon of cream of tartar per 2 tablespoons of aquafaba. This combination should be beaten together until incorporated and the aquafaba begins to increase in volume.
Stabilizing Ratio:
Cream of Tartar: 1/8 teaspoon
Aquafaba: 2 tablespoons
From Soft Peaks to Firm Peaks
The transformation from soft peaks to firm peaks is essentially a gradual process. As the meringue thickens, sugar, if called for in the recipe, should be added gradually, one tablespoon at a time, to maintain the airiness of the foam while adding sweetness and structure. Continue to beat the mixture until it reaches semi-firm or stiff peaks, indicating that the meringue is ready for use in recipes. The pinnacle of meringue perfection presents itself as glossy firm peaks that are resilient and hold their shape well.
Peak Stages:
Soft Peaks: Just beginning to hold shape, peaks curl down when beaters are lifted
Firm Peaks: Hold their shape well but still have a slight curl at the tip
