Ahhh, memories. I want to make one, but I've never bought Southern Comfort before. I'm a little scared.
SoCo is pretty good, especially as a mixer. As a Southern boy, it's sorta required drinking every so often... it's kinda like a sweet, slightly spicey whiskey. It's fairly potent, though (especially if you mix it with rum).
The drink sounds like it'd be overly sweet, but the rum and ice balance the other stuff out well.
I would also recommend it as a soporific.
Even moreso than most booze! I always have to drink a little bit to shut up the voices in my head so I can go to bed, but that one was like a morphine drip.
