1 To stir, merely for the purpose of combining ingredients, means to mix by circular motion with a spoon.

2 To beat, for the purpose of enclosing air in the mixture, means turning the ingredients over and over, and drawing the spoon, fork or beater through from underneath to the surface.

3 To cut and fold, for the purpose of combining ingredients which have already been beaten in such a way as to prevent the entangled air from escaping, means cutting through and turning over the ingredients with a fork or beater until they are thoroughly blended.
