Auvergnat cuisine is one of the most distinctive regional traditions in France, built on the produce of a high-altitude farming region: pork, potatoes, and above all cheese. The most famous dish is truffade — sliced potatoes fried slowly with lard until soft, then mixed with fresh Cantal cheese until it melts into a rich, stringy mass. It is simple, filling, and good. Aligot, the even more elastic potato-and-cheese preparation from the Aubrac plateau (just south of the Auvergne), appears on most menus in the region.
Saint-Nectaire cheese — soft, mild, with a slightly mushroomy flavour from its affinage in the volcanic caves of the Massif Central — is the cheese most associated with Clermont-Ferrand and available everywhere here at a quality impossible to replicate outside the region. The restaurants around Place de Jaude and the streets between the cathedral and Notre-Dame du Port are the most reliable zone for traditional Auvergnat cooking. Avoid tourist traps; look for menus that feature local cheeses by name.
