Yes, this does exist. And yes, it is delicious. On steak, or pasta or anything else you could possibly imagine.
5 strips of bacon, chopped
3 tablespoons butter
3 tablespoons flour
1 ½ cups chicken stock
¾ cup heavy cream
1 small onion, chopped
1 tablespoon cracked black peppercorns
In a heavy saucepan, melt butter over medium heat. Add bacon and onion and cook for 3 to 5 minutes, until fat has rendered. Add flour, then stir together and cook over low heat, stirring often, until golden and toasty-smelling, 4 to 6 minutes.
Add chicken stock and cream, and simmer over low heat until reduced to a thick, pourable gravy, about 10 minutes. Remove from heat. Stir in peppercorns, and taste for salt, adding more as needed. Serve hot.
