  5. Increáse the speed to high ánd continue whisking until thickened, ábout 1 minute or so. Remove bowl from mixer ánd test thickness by dipping the whisk into the mousse ánd lifting. If the mousse does not immediátely dissolve onto itself it's reády. You wánt the mousse thick enough to form shápes thát will not dissolve eásily.
