A problem with cooking ribs is that everyone is so competitive that they never really enjoy anyone else's ribs, because while eating them they're so busy thinking about how yours are different from theirs, and what yours are missing. They barely notice the ribs on the plate in front of them. These ribs, with peanut butter, eggplant and coriander, end up being so far outside the norm of what everyone else's ribs are that they will indeed actually get noticed. This is an "African-inspired" dish. You can round at the taste at the end with some chile-flavoured oil or Tabasco sauce to give it more pep, if desired.
