@Ragman,
A freshly brewed apple cinnamon tea is the only liquid I'd go for with cinnamon. And then only as a method of helping open my sinuses.
(never attempted killing a beer, ale, gin, rum, or anything else with cinnamon)
I never got the idiocy of hot buttered run either. If I had a cold the rum was enough.
...and what bozo thought putting butter in an alcohol beverage made sense?
