Yes, you can make mayonnaise without eggs using substitutes like aquafaba (chickpea brine) or yogurt. These alternatives create an emulsion similar to traditional mayonnaise.
Traditional mayonnaise relies on egg yolks as an emulsifier, binding oil and water-based liquids together. However, aquafaba and yogurt can mimic this function. Aquafaba, the liquid from canned chickpeas, contains proteins and starches that help create a stable emulsion. Yogurt, particularly Greek yogurt, provides thickness and tanginess while also contributing to the emulsification process. To make egg-free mayonnaise, you'll typically blend your chosen substitute (aquafaba or yogurt) with oil, an acid (like lemon juice or vinegar), and seasonings (such as mustard, salt, and pepper). The key is to slowly drizzle in the oil while blending continuously to create a smooth, creamy texture. The proportions may vary depending on the specific recipe and desired consistency.
When making mayonnaise with aquafaba, chill the aquafaba beforehand. Cold aquafaba emulsifies more easily and creates a firmer, more stable mayonnaise.
