Terrapin a la Maryland or Delmonico

Prepare and cook the terrapin the same as No. 1082. For each quart, add a half a pint of cream, reduce to half, season with salt and cayenne pepper, thicken with five raw egg-yolks diluted with half a pint of cream, and two ounces of fresh butter, toss the terrapin while adding the thickening; this must not boil, finishing with half a gill of very good sherry wine or Madeira. The sauce should be thick and served very hot.
