So by the time I'm done with the mousse, they should be nicely set until the time they were collected.
Talking about Chocolate Mousse, I've launched the Mousse Cake version officially (the ones which I made for my brother's wedding). Since I featured that in June 2008, a few people have asked. So I thought why not.
They are available in Chocolate or Mango. Do email me if you need more info.
