Tips
history
From Ouyang Xiu's 《归田录》 (Song): even a perfectly seasoned stew 'is hard to reconcile with many mouths'. The cooking metaphor naturalised into any situation of conflicting preferences.
memory
调 here is 调 ('to adjust/season'), not 调 ('to transfer'). Think of the chef 'tuning' flavours to every diner - impossible.
