“The onions of Tropea can be eaten raw in salads, or cooked. I decided to cook them with pecorino here, combining two wonderful Calabrian ingredients.”
Preheat the oven to 200°C/Gas 6. Peel off the papery onion skins. Cut a slice off the top of each onion to reveal all the inner circles, then, using a melon bailer, excavate everything apart from the 3 or 4 outer layers, leaving an onion casing; reserve the flesh. Boil the onion casing
