Mayonnaise is an emulsion of oil suspended in water

Whisking oil slowly into egg yolk creates a thick viscous suspension of fat droplets

Mayonnaise consists of up to eighty percent vegetable oil suspended inside a tiny volume of water from egg yolk and vinegar. Slow addition of oil combined with vigorous whisking breaks the fat into microscopic spheres. Lecithin coats each sphere, preventing them from joining together and creating a stable creamy sauce.
