Passard has been planning his menu based on the seasons, sourcing natural and organically grown products from artisans and farmers, including his own: Passard's desire to work with quality products led him to create three "kitchen gardens". The first took root in 2002 in the soil of Sarthe, the second in 2005 in Eure and the third in 2008 in Manche, three Départements of Western France. Three gardens in three different terroirs, giving the respective vegetables a soil-suffused signature: sand in Sarthe for carrots, asparagus and leeks; clay in Eure for celeriac and cabbage, and lastly, alluvia in Manche for aromatic herbs.
