Baileys chocolate mousse - an alternative liqueur Chocolate mousse made with Baileys is pretty much heaven.  However, what other liqueurs (not generic Baileys) would give this favorite dessert a well needed kick?  Here is the link to make the Bailey's mousse.  I want to be able to taste the liqueur as if I were drinking it, but without it overpowering the chocolate (or falling over sideways).
I'm not a massive fan of Bailey's myself, but do love a chocolate mousse. Since unless you're going way overboard with the alcohol, you're not really going to disrupt the mousse and make it soupy, you can use anything that you think goes with chocolate. Personally, I love the following paired with a good dark chocolate:


Kahlua/Tia Maria (most similar in spirit to Bailey's)
Port or madeira
Deep but not too peaty Scotch 
Dark rum (I'd leave the continental "rums" to fruit desserts, where they excel)
Brandy
Kirsch


I'd avoid lighter or delicate / floral spirits, since they don't really work (for me) with a deep dark chocolate.

I'd keep it to under about a shot per cup to avoid thinning the mousse too much. And please try a tiny pinch of salt, which the original recipe is missing but is essential for a good chocolate dessert!
