Lamb organs (heart, lungs, liver, and kidneys) with onion, garlic, rosemary, thyme, marjoram, sage and white wine, with beaten egg and pecorino mixed through.
Rinse all the offal thoroughly under cold running water. Put it in a large bowl, cover with cold water and add a splash of white wine vinegar and one of the bay leaves. Leave to soak for 1-2 hours. Drain, rinse again and pat dry.
Bring a large saucepan of unsalted water to the boil. Add all the heart, lungs and kidneys and parboil for 8 minutes. Do not add the liver. Drain into a colander, rinse under cold running water and pat dry with kitchen paper.
Cut the offal into pieces on a chopping board. Cut into 1.5 cm chunks. Keep liver separate on the board.
Beat the eggs with the grated pecorino, a pinch of salt and black pepper in a small bowl. Set aside at room temperature.
Heat extra virgin olive oil in a wide, heavy pan over a medium-high heat. Add the onion and a pinch of salt, and cook for 5 minutes until soft. Add the garlic, rosemary, thyme, marjoram, sage and the second bay leaf. Cook for 3-4 minute. Then add the wine and cooke until reduced by about half.
Add the hearts, lungs, and kidneys to the pan and cook for 8-10 minutes, turning occasionally.
Add the liver. Cook for 2 minutes only. Season with salt and pepper. Turn the heat to its lowest setting for 30 seconds, then turn it off completely and allow to cool for a few minutes..
Pour the egg mixture over the coratella. Stir constantly with a wooden spoon for 20-30 seconds until the egg is just set and integrated into the meat. The egg sets into the pieces rather than forming a smooth coating. Pull the pan away from the heat the moment it looks set - if it dries out, it is overcooked.
