Had this on 7 January for Russian Christmas. It is very nice. Did find it a bit on the sweet side so we added 3 drops of orange bitters. Many would not find it sweet. Loved the hint of chocolate and went great with the orange bitters. May try again substituting dry Curacao for the liqueur.
Thanks John. Agreed, the recipe was too sweet and also had too much volume. Hence, I've reformulated with smaller measures for a Nick & Nora glass, reducing the percentage of white cacao liqueur and adding chocolate bitters and saline. A step away from Craddock but hopefully a better cocktail. I'll update the pic as soon as I'm able.
