Tips Working with gelatin: When making mousses that are set with gelatin, chill the base mixture quickly by setting it over a larger bowl of ice and water before folding in the beaten egg whites and whipped cream. This thickens the base enough to give it a similar consistency to the beaten egg whites and whipped cream, making for a homogeneous mixture and better volume. If the base starts to set too quickly, simply place it over a bowl of warm water and stir gently for a few seconds.
To make decorative swirls in the sauce, whisk 2 tablespoons nonfat vanilla yogurt and 2 tablespoons low-fat milk until smooth. Drop small dollops of the mixture onto the sauce and draw the tip of a skewer or knife through them.
