Here the peppery flavor comes entirely from the sauce and not from pressing the peppercorns into the meat as in most steak au Poivre versions. The creamy sauce is made with plenty of crushed peppercorns, but without brandy, a common ingredient in the French version of the sauce. Morton’s, the legendary steakhouse, suggests Kansas City bone-in steaks, also known as shell steaks, strip, and NY strip. The sauce recipe here makes more than what you’ll need, but it’s tricky to make much less than 2 cups. You can freeze the peppercorn base before the cream is added for future use. Recipe from Morton’s Steak Bible, a cookbook I highly recommend.
NOTE: Peppercorn mixes are easy to find in supermarkets and specialty stores. If you have only black peppercorns, use them instead.
NOTE: You can buy veal demi-glace in a small container, usually about 1 ½ ounces, in specialty food stores, some supermarkets and even some price clubs. One of the best is More Than Gourmet Demi-Glace Gold.
