The small size means the fillets stay tender and easy to lift out whole. Serve them simply on toast or crusty bread, add them to a salad or a plate of boiled potatoes, or put the open tin out as part of a spread with olives, pickles and cheese. They suit anyone after a quick lunch, a picnic addition, or a snack to go alongside a cold beer, vermouth or a dry white. Keep a few tins on the shelf and they'll earn their place.
