I would start with a boneless ribeye roll, and cut your own steaks how thick you like them. I like half inch here. Use the end cuts for stew meat. Buffalo cubes makes some mighty fine adovado! I use dry Colorado grown chilis of course. Nothing like a pepper grown in the San Luis Valley. I think (know) the altitude makes em sweeter.
Try this one, got a batch in the fridge marinating now.
