The word 'Provence' effortlessly conjures up a sense of romance. Woodsmoke and the scent of garlic; huge, regimented fields of purple lavender; bottles of throat-catching olive oil, and bubbling pans of tomato-heavy chicken stew.

Chef Alain Ducasse - although born in Orthez in the south-west of France - knows the cuisine of the region better than most. And what he loves about it, he says, is its "simplicity and spontaneity".

"As in any culinary tradition, Provencal cuisine reflects a terroir," explains the 63-year-old restaurateur, "the nature and the culture of people living there. Yet it does it with probably a higher degree [than many other places] - with a certain flair.

"Provencal cuisine genuinely expresses the soul of the country. The tastes of the local produce is more intense, the recipes are altogether humble and supremely elegant, the recipes, transmitted [through history, largely] by women, are fantastically diverse."

The chickpea, he continues, "may well embody this spirit of Provencal cuisine: a very humble product which can be magnified by the right recipe. Many dishes are made with chickpeas or chickpea flour, for instance the socca, a delicious speciality of Nice."

Of course, Ducasse, who became the world's first chef to own restaurants carrying three Michelin stars in three cities (New York, Paris, London), does somewhat elevate Provencal cooking, particularly at his restaurant and inn, Hostellerie de l'Abbaye de la Celle, which has just celebrated its 20th anniversary.

At the core of its ethos and menu - as with Ducasse's wider businesses - is an awareness of sustainability and seasonality. "Proposing dishes with more vegetables and cereals and less meat is very important," notes Ducasse. "In parallel, we are very demanding of our producers. They have to work according to sensible environmental principles, respecting seasonality."

Ducasse was raised on a farm, before becoming an apprentice chef aged 16 and going on to train under legendary chef Roger Verge. He went on to hold more than 20 Michelin stars throughout his career and is now not just a man, but an entire culinary enterprise, with restaurants, cookery schools and consulting positions in his name.

It all comes back Ducasse's family farm though. "I remember my grandmother asking me to go to the kitchen garden and pick ripe vegetables. I remember the drops of white juice dripping from the lettuce stalk when cutting it," he recalls. "I remember the smell and taste of the roast chicken my grandmother was preparing every Sunday for the whole family. I remember the chocolate cake I dared to make for Christmas when I was 12."

Of his career achievements though, he says his most significant is "the creation of naturalite (naturalness). This is a very radical and innovative approach we developed at my Hotel Plaza Athenee, in Paris. No meat - just vegetables, cereals and fish from sustainable sources."

It is "a thought-provoking cuisine in a prestigious venue; a demanding cuisine in a glamorous three Michelin-star restaurant", he says.

You might think it would be a tricky proposition, trying to keep a handle on his many restaurants while retaining the essence of each, like at l'Abbaye. But Ducasse explains that each focuses on a single idea - to offer people "a moment of pure happiness".

Grand Marnier Souffle

Ingredients:

(Makes 6 ramekins)

For the base:

250ml milk

50g egg yolk or around 2 large eggs

50g sugar

15g cornflour

8g cream powder (as used in creme patissiere)

Zest of an orange

For the souffle:

200g egg white or around 7 eggs

80g sugar

8ml Grand Marnier

Butter for greasing

For the sponge:

100g egg yolk or around 5 eggs

80g sugar

180g egg white or around 6 eggs

30g sugar

60g flour

60g potato starch

For the syrup:

200ml water

100g sugar

Orange peel

Method:

1. Make the base. Boil the milk with the orange zest. Mix the egg yolks with the sugar to blanch them and add the cornflour and cream powder. Pour the milk over the mixture and return to the heat. Let the mixture boil for one minute and then put it in a dish. Cover in cling film, making sure the film is touching the cream to avoid the formation of a crust and allow to cool.

2. Make the sponge. Mix the egg yolks with the 80g sugar. Separately whip the egg whites, then add the whipped egg whites and the 30g sugar to the yolk/sugar mix. Stir in the flour and starch. Mix gently until the texture is even. Spread the mixture on a baking tray lined with baking paper. Bake for eight minutes at 200°C. Remove the sponge from the baking tray. Cut out discs measuring 65mm and then soak them in the syrup - just bring the water, sugar and orange peel to a boil to make that syrup.

3. Make the souffle. Grease the ramekins with butter and sprinkle with sugar. Warm the cream base and whisk in the Grand Marnier. Beat the egg whites until they are stiff and add the sugar. Gently add the whites to the cream base. Fill the ramekins to a third with the cream base and place the sponge on top. Finish filling the ramekins with the cream. To allow the souffle to rise well, gently pass your thumb around the edge of the ramekin. Bake at 185°C for 12 minutes. Serve.
