First stop is the Eléveurs Girondins where they sell the most wonderful beef from local cattle — Blonde d’Aquitaine, Limousin and Bazadais. The shop only opens a few hours every day and there is always a queue. There are certificates on the counter explaining what’s on offer this week — almost a résumé of the animal you are going to be eating. We bought some rump steak and entrecôte (well, actually, rather more than some).
