HEAVEN on EARTH!! Restaurant quality mousse here. This is not the junk you make with jello pudding mixes; this is the real deal. Unbelievable. Everyone was too full after dinner, so I decided not to serve it (they didn't even know I made it) so everyone can enjoy this with a good appetite. It's been sitting in my fridge for 2 days, staring at me, talking to me "taste me, taste me". I gave in, and OMG, this is a treasure of a recipe. As soon as the spoon went in the mousse, you hear a mouss-y sound, like bubbling air, the spoon goes in it ever so smoothly, and the taste is pure and refined, light and airy, silky and smooth. Everyone that will taste this will have to agree - it's absolutely delicious! I used a chocolate-orange liquor (Sabra brand), and used vanilla instead of orange extract. Perfect!
I really liked this recipe. I left out the orange liqueur because I didn't want to spend the money and it still had a great orange flavor. I also used this recipe to make a cake. In a spring form pan (sans bottom) I layered cake, then poured in mousse, another layer of cake, and then more mousse. I refrigerated until it set, unmolded it, then covered the outside (not top) with whipped cream. The mousse held up very well and created a very easy and presentable and TASTY cake.
I love the combination of chocolate and orange and this mousse captures both. The texture is so smooth and light. I made absolutely no substitutions. The strong flavor of the semisweet chocolate really comes thru and if you're not a fan of the semisweet, you may not care for this one. As stated in the comments, this is truly a decadent dessert.
