To make Ham Sauce (in Italian, Salsa di Prosciutto):

Ingredients:

Cut up an ounce of ham and pound it in a mortar then mix it with three dessert spoonsful of port or Musca and a teaspoonful of vinegar, a little dried basil and a pinch of spice. Boil it up, and then pass it through a sieve and warm it up in a bain-marie. Serve with roast meats. If you cannot get a sweet wine add half a teaspoonful of sugar. Australian Muscat is a good wine to use.
