Nicolas Sarkozy kept away from cheese, Jacques Chirac liked calf's head, while the French President is an unfussy eater, partial to most things.
Bernard Vaussion has built up a comprehensive picture of the culinary tastes of six presidents during his 40 years in the Elysee Palace kitchen.
During that time he has seen sauces get lighter, cheese dropped and then reinstated and truffles and crayfish fall victim to austerity.
"One avoids disclosing the dishes that are particularly appreciated. Otherwise they find themselves eating the same dish everywhere they go," he said.
"This was the case for Mr Chirac with calf's head. I made it for him two or three times because he was given it everywhere," he said.
Vaussion, who has just turned 60, started as an assistant chef during the presidency of Georges Pompidou in 1974 following a three-year stint as a sous-chef at the British Embassy in Paris.
In all, he has worked under six presidents -- Georges Pompidou, Valery Giscard d'Estaing, Francois Mitterrand, Jacques Chirac, Nicolas Sarkozy and Francois Hollande.
"I remember the apprehension of cooking for world leaders and our head of state," he said in an interview at his office at the Elysee.
"There is always a lot of pressure.... In a restaurant, if there is an error, the customer doesn't come back. Here it is me who would be asked to leave," he said.
Changes over the years included a move towards "a lighter cuisine".
"There are lot fewer dishes with sauces. The sauces are lighter. There is steam cooking.... We adhere to what is happening elsewhere (in restaurants)," he said.
The impact of the current climate of economic austerity had been felt too.
"We buy differently. Some luxury products have disappeared like truffles (and) crayfish," he said.
The chef described each president he had worked under as a "gourmand", adding however that Chirac's tastes were "a bit more developed".
As for Hollande, whose expanding girth since he was elected in 2012 is a regular topic in the media, he said: "There isn't much that he does not like. He's someone who likes to eat."
World leaders Vaussion has catered for during his four decades at the French president's official residence include former Soviet leader Mikhail Gorbachev, US President George W. Bush, the late Romanian dictator Nicolae Ceausescu and Britain's Queen Elizabeth.
But Vaussion stressed the importance of being happy to work behind the scenes.
"It's not our vocation to push ourselves forward. We stay in the shadows. We are always in the shadows," he said.
German Chancellor Angela Merkel, however, asked to meet him after one dinner to congratulate him.
And last year he met US President Barack Obama when he was invited to the White House as a member of the exclusive Club des Chef des Chefs made up of the personal chefs of current heads of state.
Vaussion will be succeeded as the head of the 20-strong Elysee team by his deputy, Guillaume Gomez, 35.
