Puree of Chicken, Partridge, Grouse or Roebuck

Raise the fillets from a roast chicken or from either two partridges or two grouse, or else one pound of the saddle of roasted venison, pound them, add four ounces of bread-crumbs, previously soaked in chicken or game broth and squeezed thoroughly, pound again and dilute this puree with simply lightly salted chicken or game broth, free of any spices, aromatics or vegetables. Strain through a sieve and warm it up without boiling, adding two ounces of butter, stirring it in well; moisten with either chicken or game broth, letting it remain sufficiently liquid so as to be easily drank from cups.
