Ham, essence of.
Take six pounds of ham; cut off all the skin and fat, and cut the lean into slices about an inch thick; lay them in the bottom of a stewpan, with slices of carrots, parsnips, six onions sliced; cover down very close, and set it over a stove. Pour on a pint of veal cullis by degrees, some fresh mushrooms cut in pieces, if to be had, if not, mushroom powder, truffles, morels, two cloves, a basil leaf, parsley, a crust of bread, and a leek. Cover down close, and let it simmer till the meat is quite dissolved. A little of this sauce will flavour any lighter sauce with great zest and delicacy.
