soy mayonnaise or regular mayonnaise

Mayonnaise is an emulsified condiment composed primarily of oil, egg yolks, and an acidic component (typically vinegar or lemon juice), whipped together to create a stable, creamy suspension. The emulsification process relies on lecithin in the egg yolks to bind the hydrophobic oil with the aqueous acidic ingredients, resulting in a thick, glossy sauce. Traditional mayonnaise originated in 18th-century France, though its exact birthplace remains disputed (Mahón, Spain, and Port Mahon are among proposed origins).\n\nSoy mayonnaise is a plant-based variant that substitutes egg yolks with soy-derived emulsifiers such as soy lecithin or aquafaba (the liquid from cooked chickpeas), along with soy milk or other plant-based ingredients. Both varieties are characterized by a rich, creamy texture and neutral to slightly tangy flavor profile. Quality mayonnaise has a pale ivory or golden hue and a smooth, spreadable consistency.

Mayonnaise is employed as a foundational condiment in sandwiches, wraps, and salads, and serves as a base for numerous derivative sauces (aioli, remoulade, tartar sauce, and thousand island dressing). In different culinary traditions—Japanese, American, and European—mayonnaise appears in applications ranging from sushi preparation to cold salads (potato salad, coleslaw, tuna salad). Soy mayonnaise functions identically to conventional mayonnaise but appeals to vegan diets and those with egg allergies; it is increasingly used in plant-based restaurants and by consumers seeking egg-free alternatives.\n\nBoth varieties emulsify effectively in vinaigrettes and whipped spreads, and both tolerate flavor additions (herbs, spices, garlic) without destabilization. Temperature sensitivity is a concern; mayonnaise should not be exposed to prolonged heat and performs optimally when refrigerated.
