Oh yeah, best episode so far. That is fucking phenomenal.
Tried a shot of Rarity when Rarity started acting like Rarity. It was delicious so I had another one. The cinnamon burn from the Goldschlager stands out a bit and the vanilla's not particularly pronounced (maybe I'm not mixing enough of it) but overall a very smooth drink.
When I tried to mix a Nightmare Moon, I ran out of Irish Creme so I'm sitting at half a glass instead of a full glass. This one's a bit of a shitkicker - the rum I'm using is fairly strong (47%) and the other two liquors are 20% each. Made one on the rocks. Overall, it's still good, and the Kahlua/Irish Creme help keep the burn to a minimum. This is actually drinkable. Though I'd advise favouring the liqueurs at about a 2:2:1 mix.
EDIT: Oh boy. Those two shots of Rarity and half a glass of Nightmare Moon have given me a good buzz ♥
