Resurrecting this thread to add some of my own ideas. After all, 'tis the season! I've been thinking about my big winter Grand Canyon hike (starting in two days) today...
-Hot Cocoa with Peppermint Schnapps. Basically a hot york peppermint patty. Tastes great with powdered whole milk added, but you'll be left with lumps of milk at the end - fair warning.
-Hot Cocoa with cinnamon, cayenne pepper and tequila
-Hot apple cider packets with Fireball, or another cinnamon whiskey
-Hot buttered rum - I tried this on a trip recently and it was pretty good, but warning about the spices, they won't mix in well put straight into the drink. The last sips of the drink were nasty. If I do this again I'll do it in multiple steps:
1) heat water and steep spices in a tea bag. Either use cinnamon and nutmeg, or - just had this idea as I was typing this - good earth sweet and spicy tea! I bet that would be amazing...
2) remove tea bag, add rum, butter and brown sugar
