• 500 g/1 lb 2 oz lambs’ sweetbreads
• 150 g/5 oz Parma ham, cut in julienne
• 40 g/1½ oz butter
• 4 tablespoons olive oil
• ½ glass Marsala
• 250 g/9 oz mixed wild mushrooms, sliced (use cultivated if necessary)
• salt and freshly ground black pepper
• crostini (½ cm/¼ in slices of French bread fried in olive oil)

Leave the sweetbreads to soak for 10 minutes, drain and put in a pan of cold water and bring to the boil. After a minute, drain the sweetbreads and refresh them under cold water. Remove the skin and membranes and dry well.

Melt the butter and oil in a heavy pan, add the sweetbreads and fry briskly until lightly browned. Add the Parma ham, drain off as much fat as possible, pour over the Marsala and reduce rapidly until a glaze comes on the sauce.

Fry the wild mushrooms in oil, remove with a perforated spoon and add to the sweetbreads. Season with salt and pepper.

Serve with the crostini fried in olive oil.
