Chickpeas, also known as garbanzo beans, are a nutritional powerhouse, packed with protein, fiber, and essential vitamins and minerals. Whether you’re whipping up hummus, adding them to salads, or enjoying a hearty chickpea curry, these versatile legumes are a staple in many kitchens. But there’s one question that often arises when working with canned chickpeas: should you drain them? The answer, surprisingly, isn’t always straightforward. It depends on what you’re making, and the magical liquid they’re swimming in, known as aquafaba, can be a game-changer in the kitchen.
Understanding Chickpea Liquid: Aquafaba
The liquid found in canned chickpeas, often dismissed and poured down the drain, is called aquafaba. Aquafaba is derived from the Latin words “aqua” (water) and “faba” (bean). This humble liquid is actually a nutritional and culinary treasure. It’s created during the cooking process of chickpeas, as starches and proteins leach out into the water. These dissolved solids give aquafaba its unique properties, allowing it to mimic egg whites in various recipes.
Aquafaba has become a sensation in the vegan and vegetarian communities, as it provides a plant-based alternative to eggs in meringues, mousses, macarons, and other desserts. Beyond its use as an egg replacer, aquafaba can also be used as a binder, thickener, and emulsifier in a wide range of dishes. Its versatility makes it a valuable ingredient for both sweet and savory preparations.
The Composition of Aquafaba
Aquafaba primarily consists of water, carbohydrates (mostly starches), and proteins. The exact composition can vary depending on the type of chickpea, the cooking time, and the canning process. Generally, aquafaba is low in calories and fat, but it does contain trace amounts of vitamins and minerals that are naturally present in chickpeas.
The key to aquafaba’s functionality lies in its protein and starch content. The proteins act as surfactants, reducing surface tension and allowing air bubbles to form, which is crucial for creating foams like meringues. The starches contribute to its thickening and binding properties.
Benefits of Using Aquafaba
Using aquafaba offers several advantages. It’s a plant-based alternative to eggs, making it suitable for vegans and those with egg allergies. It’s also a sustainable ingredient, as it utilizes a byproduct that would otherwise be discarded. Aquafaba can add a unique texture and flavor to dishes, enhancing their overall appeal.
Furthermore, aquafaba is relatively inexpensive, as it’s readily available in canned chickpeas. It’s also easy to work with, requiring minimal preparation before use. With a little experimentation, you can discover the many ways aquafaba can elevate your cooking.
When to Drain Chickpeas
Draining chickpeas is the appropriate action in many situations. The key is to understand when the aquafaba’s properties aren’t needed or may even be detrimental to the dish.
When the Liquid Isn’t Needed for Binding or Thickening
If your recipe doesn’t rely on the binding or thickening properties of aquafaba, draining the chickpeas is generally recommended. For instance, if you’re adding chickpeas to a salad for texture and protein, the liquid is unnecessary and may even make the salad soggy. Similarly, when roasting chickpeas for a crunchy snack, draining them beforehand ensures they crisp up properly in the oven.
Draining ensures the chickpeas themselves are the primary flavor component, and it prevents the dish from becoming diluted or having an unwanted texture.
When the Flavor of the Aquafaba Is Undesirable
Although aquafaba has a subtle flavor, it can sometimes impart a slightly beany taste to dishes. In some cases, this flavor may be undesirable, especially if you’re aiming for a neutral or delicate flavor profile. Draining the chickpeas removes this potential flavor interference, allowing the other ingredients to shine.
This is particularly important in recipes where the chickpeas are not the main ingredient, but rather a supporting component.
When the Recipe Specifies Drained Chickpeas
Many recipes explicitly call for drained chickpeas. In these cases, it’s crucial to follow the instructions to achieve the intended result. The recipe developer has likely considered the impact of the liquid on the dish’s texture, flavor, and overall outcome. Ignoring this instruction could lead to unexpected results.
Always read the recipe carefully and adhere to the specified instructions regarding draining the chickpeas.
When to Keep the Chickpea Liquid: Aquafaba in Action
Aquafaba’s unique properties make it a valuable ingredient in various culinary applications. Knowing when to retain the chickpea liquid can significantly enhance your cooking and baking endeavors.
Using Aquafaba as an Egg Replacer
Aquafaba’s most celebrated use is as an egg replacer. Its ability to mimic egg whites makes it ideal for vegan and allergy-friendly recipes. It can be whipped into meringues, mousses, and other desserts that traditionally rely on eggs for their structure and texture.
To use aquafaba as an egg replacer, you typically need to reduce it by simmering it on the stove until it reaches a consistency similar to egg whites. This concentrates the proteins and starches, enhancing its foaming and binding properties.
Enhancing Hummus Texture
Many hummus recipes call for adding a small amount of aquafaba to achieve a smoother, creamier texture. The liquid acts as an emulsifier, helping to bind the ingredients together and create a velvety consistency. Experiment with adding a tablespoon or two of aquafaba to your hummus recipe to see if it enhances the texture to your liking.
Adding aquafaba can result in a lighter, airier hummus, as opposed to a dense and pasty one.
As a Binding Agent in Vegan Burgers and Meatballs
Aquafaba can also serve as a binding agent in vegan burgers and meatballs. It helps to hold the ingredients together, preventing them from falling apart during cooking. The proteins in aquafaba coagulate when heated, creating a cohesive structure that binds the ingredients.
Add a few tablespoons of aquafaba to your vegan burger or meatball mixture and mix well. Allow the mixture to rest for a few minutes before shaping and cooking to allow the aquafaba to fully bind the ingredients.
In Baking: Cakes, Cookies, and More
Aquafaba can be used in a variety of baking applications. It can replace eggs in cakes, cookies, and other baked goods, providing moisture, structure, and a tender crumb. It’s also used in vegan macarons, often considered one of the most challenging vegan bakes.
When substituting aquafaba for eggs in baking, the general rule of thumb is to use 3 tablespoons of aquafaba per whole egg. However, some experimentation may be required to achieve the desired result, as different recipes may require slight adjustments.
Practical Tips for Working with Chickpeas and Aquafaba
To make the most of chickpeas and aquafaba, consider these practical tips:
- Choosing the Right Chickpeas: Opt for canned chickpeas with no added salt or preservatives, if possible. This will give you more control over the flavor of your dish and ensure the aquafaba is as pure as possible.
- Storing Aquafaba: Leftover aquafaba can be stored in an airtight container in the refrigerator for up to a week. It can also be frozen in ice cube trays for later use. Thaw it in the refrigerator before using.
- Reducing Aquafaba: To enhance its foaming and binding properties, simmer aquafaba on the stove until it is reduced by about one-third. This concentrates the proteins and starches, making it more effective as an egg replacer.
- Experimenting with Flavors: Aquafaba can sometimes impart a slightly beany flavor. You can mask this flavor by adding spices, herbs, or other flavorings to your dish.
- Checking Consistency: The consistency of aquafaba can vary depending on the brand of canned chickpeas. Adjust the amount of aquafaba you use in your recipe based on its thickness.
