Sweet and blue

Antoine Roussel was a peasant farmer who lived some 40 km outside Clermont-Ferrand. Around 1855, he stumbled on the idea of seeding the milk from his dairy herd with the mould found on rye bread, then piercing the curd with a knitting needle to introduce air. The result was Bleu d’Auvergne, which achieved PDO status in 1996. Bleu d’Auvergne is the most famous of the blueveined cheeses produced in the Massif Central; the production area extends from Puy-de-Dôme to Cantal, and includes Aveyron, Corrèze, Haute-Loire, Lot and Lozère. It takes 20 to 25 litres of milk to produce a Roquefort which weighs 2 to 3 kg after being aged for a minimum of 4 weeks. Penicillium Roqueforti is added to the milk in the initial stages, but forms its familiar blue veins during maturation, when the salted cheese is pierced by hand using needles. This makes it creamy and full flavoured – the hallmarks of Bleu d’Auvergne.
