These aren't the luscious slow-cooked sort of ribs, but they were good and only took 45 min start to finish.

Cut into four rib sections; heat oil in pressure cooker; brown ribs in oil; discard oil; add sake, rice vinegar, hoisin or soy sauce, star anise, garlic, pepper, onion; cover pressure cooker; bring to high pressure and cook for 15 min; release pressure, remove ribs; boil the liquid in the pressure cooker to reduce, for 15 minutes, then stir in some cornstarch; meanwhile, broil ribs in toaster oven, 5 min per side; assemble and serve to kids as evening snack.
