If jelly is whipped or whisked just prior to setting, tiny bubbles of air are enclosed. These impart a lightness of texture both stimulating and refreshing to the palate. The addition of egg white, slightly whisked and then whipped with the cold liquid jelly, increases the volume of the jellied foam and also adds to its nutritive value without unduly diluting the flavour, although a strongly-flavoured jelly is necessary if more than I egg white is used. This is a sweet very suitable for, and popular with, children and invalids.
