With the rising cost and reduced availability of eggs due to avian influenza, many home bakers are exploring alternative ingredients for their recipes. Kristine Villarroel conducted an experiment using five common egg substitutes—applesauce, silken tofu, mayonnaise, chia seeds, and aquafaba—to bake brownies from a classic boxed mix. Her findings revealed that while each substitute had unique properties, only three stood out as viable options for future baking endeavors. This article delves into the results of her experiment and highlights the most successful alternatives.

The ongoing bird flu outbreak has significantly impacted egg prices and supply, prompting bakers to seek cost-effective substitutes. To address this challenge, Villarroel chose Betty Crocker’s Fudge brownie mix as the base for her experiment. Each batch required 1/2 cup of oil, 2 tablespoons of water, and two eggs, which she replaced with various alternatives. The goal was to identify a cheaper yet effective substitute that could maintain the quality of the baked goods.

Villarroel's first attempt involved using applesauce as a binder and emulsifier. Despite its moisture-retaining properties, the resulting batter was runny and lumpy. Even after adjusting the baking time, the brownies remained undercooked inside and felt oily. Although they tasted fudgy, the texture left much to be desired, indicating that applesauce might not be the best choice for this particular recipe.

Next, Villarroel experimented with silken tofu. Initially hesitant due to its unfamiliarity in baking, she found that tofu blended smoothly into the batter, creating a thicker and more cohesive mixture compared to applesauce. The baked brownies rose well and had a light, almost cake-like texture. While slightly crumbly, the tofu brownies were notably less oily and more appealing than the applesauce version.

The third trial used mayonnaise, an ingredient made from eggs and oil. Despite skepticism, Villarroel proceeded with caution. The batter was thick but struggled to emulsify properly, leading to a prolonged baking time. The final product was overly chewy and had an unpleasant taste, making it the least favored among all substitutes tested.

Chia seeds, known for their binding capabilities, were next on the list. Villarroel mixed the seeds with water to create a gelatinous "chia egg" before incorporating it into the batter. The result was a smooth, textured mixture that spread easily in the pan. After baking, the brownies had a crispy edge and a rich, fudgy interior. The added crunch from the chia seeds made these brownies a standout favorite.

Lastly, Villarroel tried aquafaba, the liquid from canned chickpeas, which is often used as an egg white replacement. The mixture turned out to be very runny but emulsified well without separating. The baked brownies had a unique appearance, with a crispy top and caved-in center, yet they were deliciously fudgy and rich. This combination of textures made the aquafaba brownies another success story.

In conclusion, Villarroel's experiment highlighted that silken tofu, chia seeds, and aquafaba emerged as the most promising egg substitutes for baking brownies. These alternatives not only provided satisfactory results in terms of texture and taste but also offered cost savings compared to traditional eggs. For those looking to adapt their recipes during times of scarcity or for dietary preferences, these substitutes present viable and enjoyable options.
