I agree that it's a bit too much citrus. I really want the allspice to be the hero of the drink, rather than an afterthought. Might try simply reducing the lime to 1/4 at first.
Man, am I bad at floating cream. The drink is not bad, but no matter how carefully I pour the single cream over the back of that spoon, I get cream throughout the drink.
When your in laws leave a bottle of mountain dew in the fridge, you may as well try it... Used whiskey x2, didn't use sugar syrup, and still a bit too sweet.
I'm realizing that if I force myself to drink more Campari drinks, I start to like more Campari drinks. Not sure if it's some kind of Stockholm Syndrome, but this drink is tasty.
