DuClaw Brewing out of Baltimore makes one of these, called Sweet Baby Jesus. I was surprised at how good this stuff was. I googled a clone recipe, and didn't come up with much. Someone here on HBT has listed the ingredients, that could be a starting point for you. Good luck! Let us know what you decide to do.
