In a skillet set over medium heat, melt the butter or warm the oil. Add the finely chopped shallots and minced garlic, cooking until softened and fragrant, which typically takes 2–3 minutes. Ensure not to brown the aromatics.
02 -
While the aromatics cook, coarsely crush the black peppercorns using a mortar and pestle. Aim for a textured grind, leaving some larger fragments for a more pronounced flavor and mouthfeel.

Pour the brandy, wine, or stock into the skillet. Use a wooden spoon or spatula to scrape any browned bits from the bottom of the pan, incorporating their rich flavors into the liquid.
04 -
Stir in the chicken or beef stock along with the heavy cream. Bring the mixture to a gentle simmer, allowing it to reduce slightly until the sauce thickens enough to lightly coat the back of a spoon.
05 -
Remove the pan from the heat. Whisk in the Dijon mustard, if desired. Season the sauce with salt and a few drops of Worcestershire sauce to taste. For an exceptionally smooth consistency, the sauce may be strained before serving.

If a thicker sauce is preferred, continue to reduce it over low heat. To thin the sauce, incorporate an additional splash of stock or cream. Serve the warm peppercorn sauce immediately over grilled steak, roasted chicken, or sautéed vegetables.
