c. mayonnaise

Mayonnaise is an emulsified condiment composed primarily of egg yolks, oil, and an acidic component (typically vinegar or lemon juice). The ingredient originated in the Mediterranean, with some culinary historians attributing it to the port city of Mahón in Menorca, Spain, though French culinary tradition claims it as part of classical French cuisine. The emulsion forms through mechanical whisking, wherein the lecithin in egg yolks acts as an emulsifier, allowing the immiscible oil and acidic liquid to combine into a creamy, stable suspension. Commercial and home versions exist, with variations in oil type, acidity level, and added ingredients like mustard or spices that subtly alter flavor and texture.

The condiment has a pale ivory to light yellow color, rich and creamy mouthfeel, and a predominantly savory, slightly acidic taste with underlying notes from the oil used. Variations include aioli (garlic-forward), remoulade (with relishes and herbs), and Japanese Kewpie mayonnaise (made with egg yolks only and containing a hint of sweetness).

Mayonnaise serves as both a binding agent and flavor base across numerous cuisines. It is fundamental to sandwich construction, particularly in American and Northern European cooking, where it functions as a condiment and moisture provider. In French cuisine, mayonnaise is a mother sauce from which derivative sauces derive; it appears in classic preparations like sauce gribiche and various aspic accompaniments. In Asian cuisines, particularly Japanese, mayonnaise is used in sushi and noodle dishes, while in Spanish and Portuguese cooking it anchors dishes like pan con tomate variants. The ingredient also functions as an emulsifying base for compound sauces, dressings, and potato or egg salads.
