Description
An emulsion is a stable dispersion of two immiscible liquids — typically fat and water — where droplets of one are suspended in the other. Without an emulsifier, oil and water separate in seconds. With the right emulsifier at the right concentration, an emulsion can remain stable for days, weeks, or indefinitely. Understanding emulsification at the molecular level transforms sauce-making from a sequence of memorised steps into a set of physical principles applicable across every fat-water combination in the kitchen.

The Thread
—The science of emulsification is universal
—the cultural expressions are endlessly diverse
—Aioli (Provençal garlic emulsion) and Japanese tare emulsification in ramen broth use the same physical principles
—Turkish tarator (walnut-bread emulsion) achieves stability through a different protein mechanism (walnut proteins) than egg-yolk lecithin
—Southeast Asian nam prik pao (a paste emulsion) uses chilli seed pectin as a partial emulsifier
