What technique is used to separate egg yolks from egg whites?

The technique used to separate egg yolks from egg whites is referred to as egg separation. This process involves using simple methods, such as gently cracking the egg and transferring the yolk between the two halves of the shell or using an egg separator tool. The goal is to keep the yolk intact while allowing the whites to fall away, enabling chefs to use each component as needed in various recipes.

Whisking, beating, and emulsifying are techniques that involve mixing or combining ingredients rather than specifically isolating one part of an egg from another. Whisking typically incorporates air into a mixture, beating combines ingredients more vigorously, and emulsifying refers to combining two ingredients that normally do not mix, like oil and water. Therefore, these methods do not apply to the task of separating yolks from whites, making egg separation the correct choice.
