Take the very best pork you can get - one-third fat and two-thirds lean - and chop on a block with a kitchen cleaver. When half chopped, season with black pepper, salt and sage, rubbed through a sieve, and then finish the chopping; but do not cut the meat too fine, as in that case the juice of the meat will be lost. Make the mixture up into patties, and fry on a common pan, placed in the oven of the stove, taking care not to cook them hard. Veal is a good substitute for the lean pork in making these sausages, which are much better if made one day before cooking.
