Mousse means foam in French. Going by that definition, this dessert should be light as foam. I scourged the internet for a light eggless version to make for our anniversary, and ended up grabbing bits and pieces from a few sites, see Recipe notes for links. This is Raj's favorite dessert. I made 4 glasses, and he polished off 2 of them as soon as they were just about set. I think he liked it!
