I just read the Karagitz blog Adam mentioned, noting both the Mexican mole and c.c.fatback comments.
To really get nutritionally obscene, I'm thinking large chunks of chicharones (deep fried pig skin) filled with crunchy peanut butter and then coated with Nestlés Abuelita (cinnamon chocolate).
To die for. Literally.
I'm really health conscious, so I wouldn't touch such bacon even with a ten foot pole. Personally, if I had to make something similar to fudge covered bacon, I would at least use carob (from Holy Food Imports, www.holyfoodimports.com) in place of chocolate, so it would be somewhat healthier.
I love chocolate and I love bacon, and I think this could be an interesting combination.
I wonder if you could choose between milk chocolate and dark chocolate. White chocolate could be an even more interesting combination.
