David caradine Cocktail
Mix in the order: cacao, menthe, whiskey, milk. Try to keep the layers separate. Float on the back of a spoon, tilt the glass and pour very gently, etc. I suggest tilting the glass. When you tilt the glass you can, when pouring the cream/milk, rotate the glass causing the cream to swirl down through the other layers which looks good. Serve in an apertif glass.
