Okay, so this is really bothering me. I know I read in a thread somewhere about caramelizing sugar in a pan and adding it to your rum (amongst other ingredients/steps) to make a dark rum. I would really like to hear some recipes on this or if someone could provide me with a link to a thread they know of. I must of read several of these type rum flavoring articles/threads and now that I need one I can't find one!! My still is about finished my 2nd rum run and my first run I had a puke and have some off colored spirit that I would like to make a dark rum but can't find that danged thread!

Thanks for the help!!
