Step 1
Organic
Answer
Organic eggs come from hens that are raised without the use of growth hormones or antibiotics. These birds are fed an organic diet which excludes artificial pesticides and fertilizers. This ensures that the eggs produced meet the organic standards, promoting animal welfare and environmental sustainability.
Step 2
Lecithin
Answer
Lecithin, primarily found in egg yolk, is a natural emulsifier. It possesses the unique ability to bind together two immiscible liquids, such as oil and vinegar. The lecithin molecule features a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail. The hydrophilic head attaches itself to water, while the hydrophobic tail connects to oil, facilitating a stable mixture and preventing the two substances from separating. This property is essential in various culinary and food processing applications.
