Food Emulsions Knowledge Quiz – When Oil Meets Water
An emulsion is a mixture of two liquids that normally do not mix, like oil and water, with tiny droplets of one dispersed in the other. Many sauces, dressings and dairy products are emulsions held together by emulsifiers.
Egg yolk contains lecithin, which helps mayonnaise and hollandaise stay creamy. Vinaigrette is a temporary emulsion that separates, but mustard helps stabilize it. Milk is fat dispersed in water, while butter is water dispersed in fat.
Emulsions can break if overheated or if oil is added too fast. Chefs rescue them by whisking the broken sauce slowly into a fresh base. Classic emulsified sauces include beurre blanc, aioli and béarnaise.
