Potatoes au gratin. Sliced potatoes baked with cream and browned on top. Cheese and eggs are sometimes added.
"St Peter fish." John Dory. A high quality, plump, flattish fish with a golden sheen, with an ugly but amiable face. It was first associated with Zeus, then with St Peter, as evidenced by the ‘finger marks’ left by him when he picked it up to remove a coin from its mouth to pay some taxes. It is also plaice.
