Just read an article about Impossible Burgers (disclosure: I haven't eaten one yet). In "Impossible Foods’ rising empire of almost-meat", Chris Ip tells the story of Impossible Foods, which among other things will be making an "Impossible Whopper" for a Burger King in St. Louis:
Something in the story took me back to this one time when I dropped acid ... would have been early-70s, I guess. It starts with this video:
At one point, the Director of Research for Impossible Foods explains that flavor comes to us in part via our nose ... the nose "tells you what you're eating". It was that point which led to my "acid flashback". As is often the case with seemingly mundane events that happened when I was tripping, I can remember this as if it were yesterday.
I was sitting at the dinner table at home ... I was living there, as were my three youngest siblings. We were eating hot dogs, and I had done some psychedelics. I was holding a hot dog with no condiments, staring into space, trying to act "normal" so Mom and Dad wouldn't suspect anything. One sibling passed the mustard across the table to another sibling. I could smell mustard as it crossed my line of sight. And then, suddenly, I could also taste the mustard, just as I would have if I'd put it on my hot dog in the first place. I smelled it ... I tasted it.
Now I know that was science at work. Or nature, not sure what to call it, exactly.
