I think what the parent comment is saying is that, lobster was likely introduced as an elite/rare dish to people in the current century increasing the appeal

That is exactly the point they are trying to make... that you enjoyed it BECAUSE you thought of it as a delicacy and not as peasant food.

I think the point is a little overwrought, really... while our expectation is part of what makes it taste good, it doesn't completely change what we think... there are a lot of foods that are considered delicacies that a lot of people don't like.

>that you enjoyed it BECAUSE you thought of it as a delicacy and not as peasant food

When I was a child, I didn't even know the word "delicacy" let alone have any concept of whether what I was eating was a delicacy or not.

Like I said, I disagree with the person's overall thesis, just pointing out what they were trying to say.
