You can absolutely go through a can of chickpeas and pop all of them out of their thin papery skins by hand, or by rubbing them between two dry kitchen towels. In our experience, it's just not worth it, though. It will be slightly smoother, but when I serve it with crunchy pita chips or vegetables, I don't notice the extra smoothness! If I were using this as a sandwich spread, I would take the time to make it extra smooth to mimic mayo.
