I finally succeeded! Evil chocolate mousse: I could never have the right firmness! After few (I won’t mention the scary number) trials, here is the recipe that led me to the right dessert. I got inspired from Mr Lebovitz, who confesses he adapted his recipe from Mrs Child’s. I guess there is no “perfect recipe”, you have to make your own. Anyway, if you do trust me, you could make a good mousse with these proportions and steps. Good luck and ENJOY!
