Ok so my cake questions might have something to do with this conversation with my husband.
ME: What would you like for your birthday cake?
HIM: A chocolate mousse cake please
ME: Um. Try again. Maybe something that I've made before
HIM: Nah. I have faith in you
ME: through gritted teeth Challenge excepted.
A little bit later
ME: Here's one. It has a little bit of liqueur in there. How about kalua?
HIM: Nah just chocolate. Nothing else
ME: through gritted teeth Challenge excepted
So I have collected my ingredients and will be commencing Operation Chocolate Mousse Cake Sample this afternoon. I shall post the results later.
Mozart liqueur is highly alcoholic chocolate - maybe use that instead of Kahlua? Wouldn't dilute the OTT chocoholism of the recipie. And vanilla extract (a little bit) will also accentuate the chocolate taste.
