I like the smell of this better than the taste; there’s a lot more creamy vanilla and fruit than you’d expect from the spicy description. The black tea taste (ceylon?) is fairly pronounced, and it’s… more sour than sweet? I’m not really a fan of sour teas, so the tart fruit undertone is putting me off a little, especially compared to the sweet aroma of the dry leaves and the liqueur.
I wouldn’t want to add anything to this, though; I think any sort of cream or sweetener would overwhelm it (unless perhaps you brew it stronger)
Edit: Wow, this is getting a lot softer as it cools, more what I expected from the scent. Less sour, more cream.
