We need to think about what cooking is, what context it takes place in and what its relationship to the world of art is. If there were criticisms of my presence at Documenta, that's a good thing because it means we were doing something new. Your mission in creating something artistic is to produce something new and polemical.

For me to go to a restaurant and eat something that is not only good, but totally new, is a double thrill. Double the enjoyment.

What's wrong with transforming food?

Everywhere the sky is blue. There are a multitude of cuisines and dishes. I think of them as the languages and dialects of food.

The avant-garde has always existed throughout the history of mankind. The good things from the avant-garde last and eventually, after many years, become tradition and people forget they were ever part of the avant-garde. The kitchen is a living discipline, always evolving, and there will always be cutting edge things that over the years, ends up being part of tradition.

People need to understand. If they go to a show on Broadway and find seventy people working but only fifty spectators, how much would the ticket cost? That's what El Bulli's about. There are seventy actors who are playing for just fifty spectators. Is the price expensive? It's relative. How much does a normal dinner at a five-star hotel restaurant cost? Four hundred dollars. It's the same as El Bulli. But you can also think of it this way: How much would it cost to eat something that nobody else is eating?

It’s very hard to be an innovator at the highest level in any discipline. For some chefs it’s merely about combining ingredients, but that’s something you can do with your eyes closed.
