I think its just a sudden crave of taste and it is represented via familiarity.

eg: craving something sweet or salty

that person just associated the salty with the wings.

youll find this with some people will crave gummy worms or specific chocolate bar and its just the sweetness.

later in life as you learn how your body works youll just grab the closest thing available if that thing isnt around.

The boston legal thing i get cuz once in a while dont we all crave a bit of James Spader now and again? that’s a flavour you cant substitute.
