The terms Mousses and Mousselines can be used to describe hot and cold preparations; that which differentiates between Mousse and Mousseline is not the composition but its moulding. A Mousse, hot or cold, is made in a large mould of which the size is generally sufficient for more than one person. The Mousselines are moulded either with spoons, a piping bag or in special moulds having the form of large Quenelles, and one only is served per person. The Soufflés are moulded in small cassolettes or soufflé moulds.
