Notes
A completely different drink from the one posted by DrunkLab.
Cinnamon bark syrup made by steeping 1/2 ounce of cassia cinnamon sticks with 1 cup water and 1 cup superfine sugar. Heat, then let sit overnight before straining thru cheesecloth.
The cognac and cinnamon would make for a lovely holiday drink.
