I think my current absinthe might just be bad. I usually like absinthe in various cocktails but the one I have just adds a bitterness that becomes even more pronounced the more you add to it. I'm sure the cocktail is good - it is actually quite balanced with my ingredients as well - but make sure to use a decent absinthe.
Just made my first attempt at this. Only had double cream not single. No matter. Silky smooth and very strong. This will absolutely wow guests after dinner.
I'm not an Absinthe fan, so I didn't particularly enjoy this but I have to say I was surprised at just how well the Absinthe, chocolate and cream went together. The booziness (7) and sweetness (5) ratings above are spot on. Definitely worth a try if you like absinthe. Even if you don't, this does tame the anise flavor quite a bit.
