EdWort says, "this makes a great Grog in the winter time. Take a quart in a sauce pan, add some rum, turbinado sugar, and float a cinnamon stick in it and simmer for a while. Serve hot in mugs. It'll warm you right up."
My question is by simmering, aren't you in essence evaporating the alcohol, similar to the process of distilling in spirits such as bourbon? I guess a lid would be adequate to keep the alcohol from leaving the pan? Something to perhaps keep in mind.
Anyway what have you experimented with? I've only tried a combo of sugar, vanilla, and a half stick of cinnamon and enjoyed it. I was thinking of giving honey a shot.
