As I recall the Buttered Rum recipe was similar to the recipe here, but no white sugar, same total amount but all brown. Also had ground cloves, ground cinnamon instead of stick, and orange zest. Heated all that to boiling, and at same time, melt salted butter. pour the liquid in a cup, add the rum to taste, and pour over the hot melted butter and stir. One of these apres ski, or just on a cold winters night would be great. 4 guys pouring through a half gallon of rum with this is A REALLY BAD IDEA, but in our defense we were 20 and bad ideas were our bread and butter. Like the meme says, wisdom comes from experience and experience comes from bad ideas.
