  • 1 tablespoon unsalted butter

Recipe notes
This recipe combines veal demi-glace with black truffle butter for a velvety sauce that is great on prime rib. Try it on steaks hot off the grill, roasted beef tenderloin, or any of your favorite cuts of beef and veal. Whether in a robust reduction or a creamy butter sauce, a small amount of acid at the end of cooking can enhance depth and complexity. A splash of vinegar or lemon juice is all it takes to round out the flavor and balance the richness of fats or the intensity of ingredients. This added brightness can make sauces taste more vibrant and pronounced without overwhelming the dish.
RECIPE Preparation
  1. In a medium saucepot, melt the unsalted butter over medium heat. Add the minced shallots and garlic, cooking until softened and fragrant (about 3-4 minutes).
  2. Stir in the tomato paste and cook for about 30 seconds, stirring to prevent burning.
  3. Deglaze the pan with red wine and bring to a simmer. Cook, reducing the wine until only ¼ of the liquid remains (about 5 minutes).
  4. Stir in the fresh thyme.
  5. Add three tubs of veal demi-glace to the pot. Stir and let the sauce reduce to about ¾ of its original volume, or more for a thicker consistency (about 10-15 minutes on low heat).
  6. Once the demi-glace has reduced, turn off the heat and whisk in the cubed black truffle butter until it emulsifies completely into the sauce.
  7. Taste the sauce and adjust with salt and pepper as needed. Finish with a splash of red wine vinegar.
  8. Serve with sliced portions of prime rib. Alternatively, you can enjoy this sauce with steaks off the grill, roasted beef tenderloin, and any of your favorite beef or veal cuts.
