Villeroi Sauce

Put into a sautoire with some butter two ounces of lean ham; fry for a few minutes, then drain off the butter and moisten the ham with one gill of white wine; reduce it until dry, then pour in a pint of veloute (No. 415) and season the sauce with mignonette and nutmeg; reduce again and then thicken with four egg-yolks diluted in a gill of cream; let the sauce boil up once or twice while stirring it at the bottom of the sautoire with a reducing spatula, then strain it through a tammy (No. 159), and mix in with it some chopped and drained mushrooms, also a teaspoonful of chopped parsley or fine herbs. This sauce should be more consistent than allemande sauce and it is used only when beginning to cool, to coat cold meats. It can also be soubised by adding to it a few tablespoonfuls of soubise sauce (No. 543).
