Richard, I just made the refried black beans. Not too shabby there, dude!! The bacon fat is heaven in it!! I added salt, pepper and adobo seasoning to it, as well as some garlic.
It's still not that same color that I saw at the one mexican place in New Hope. Those beans were more violet in color (a blue purple color).
I'm saving my mom and dad some of these beans, as they love refried beans. We'll see what they think about the bacon flavor and the fact that they're black beans.
