When I left to go into apprenticeship in 1949, it was only four years after the war, and people don't realize, we still had tickets for butter, meat and so forth in France until 1947. It's not like the end of the war, everything was plentiful - it wasn't.

I tell a student that the most important class you can take is technique. A great chef is first a great technician. 'If you are a jeweler, or a surgeon or a cook, you have to know the trade in your hand. You have to learn the process. You learn it through endless repetition until it belongs to you.

Basically, I go to the local farmer's market and decide to what to cook then, depending on what I find. Either my wife or I cook, and we usually finish a bottle or two of wine by the time we are done cooking and eating.

The menus that remain, for me, are really the menus that you have with your good friends, with your wife, with your mother, with your kids. These are what stay in your mind.

I say: If you don't know how to cook, I'm sure you have at least one friend who knows how to cook. Well, call that friend and say, 'Can I come next time and can I bring some food and can I come an hour or two hours ahead and watch you and help you?'

All the great chefs I know - Thomas Keller, Jean-Georges Vongerichten - they are technicians first.

I cooked at the White House for Easter, last year, with Michelle Obama. But it more had to do with cooking from the organic garden, and her message. I took my daughter and granddaughter there, and they were really charming, it was great.
