Jambon de Bayonne PGI is France's celebrated air-dried ham from the Adour basin in the south-west, salted with local Salies-de-Béarn salt and cured through the region's mild winters. The finest are marked with the Basque lauburu cross seared into the skin.
The imitation is any generic French or ‘Bayonne-style’ dry-cured ham. The PGI and the Adour-basin origin are the guarantee.
