The bikers begin their Sardinian adventure in the small town of Cagliari, where everyone is in high spirits for the feast of St Efisio. The locals are dressed in traditional garb to parade through the town on decorated bullock carts. The bikers join in the fun by cooking a local speciality - almond and orange cakes. Leaving the festivities behind, they head west to meet the tuna fishermen of Carloforte. Here, tuna is known as the "pig of the sea" and nose-to-tail eating is the norm. After seeing the locals' unique form of fishing, the bikers meet a chef who serves up platters of tuna treated the Carloforte way. Featured recipes include frutti di mare with saffron fregola (seafood with fregola pasta and saffron), torta menjar blanc (lemon cream tart) and lamb and fennel stew with fennel salad.
