If Albert Adria or his brother Ferran are not culinary artists than no one is. Here, in Spanish, he says that the question is ultimately up to the diner to answer.
I had filmed several other interviews, but alas, audio problems from trying to use some new equipment made them unusable. I hope that you have found this series as interesting to watch and listen to as I did asking the questions and filming. The video quality certainly could have and should have been much better, but I don't think that lessens what these individual culinarians had to say.
