What's the appeal of watching your food be prepared? I would have said, say, cleanliness, but perhaps there's something much deeper.
If we ask Roland Barthes (from memory so misquotation is mine) we'd see that
"If Japanese cooking is always performed in front of the eventual diner it is probably because it is important to consecrate by spectacle the death of what is being eaten"
Is this true? If so what does it tell us?
Would be interesting to make a catalogue of sacrificial undertones in everyday activities. Perhaps non-religious activities, to be safe.
Would also be interesting to know whether the consecration he mentions appeals mostly to the Japanese sensibility, or whether it is more general.... Ideas, examples?
