Rick Stein travels to St Ives to meet one of Britain's little-known artists, Alfred Wallis. In the shadow of Bodmin Moor, Rick visits a very rare collection of medieval stained-glass windows in the church of St Neot. It is here he ticks off an item on his bucket list by taking part in a rather unusual celebration called Oak Apple Day, marking the occasion when Charles II became king. And on the Cornish border with Devon, Rick meets a lamb farmer who is on a mission to rear the best lamb in the county, inspiring Rick to cook a delicious lamb stew called a Navarin.
