This professional-grade vermouth beef jus is the ultimate finishing touch for pan-seared meats. By reducing beef stock with aromatics and botanical vermouth, you create an intensely savory, silky sauce that rivals any high-end steakhouse.
Melt the unsalted butter in a small skillet or saucepan over medium-low heat. Add the finely diced shallot and sauté for 4 to 5 minutes until softened and translucent. Do not let the shallots brown, as this will affect the final color and delicacy of the jus.
Pour in the dry vermouth and increase the heat to medium-high. Bring the liquid to a simmer, using a wooden spoon to scrape the bottom of the pan to release any caramelized bits (fond). Continue to cook until the liquid has almost completely evaporated and the alcohol has cooked out.
Add the beef stock to the pan. Simmer for approximately 6 to 7 minutes, or until the liquid has reduced by three-quarters. The exact time will vary depending on your stove's heat and the surface area of your pan.
Stir in the cream and continue to simmer for another 4 minutes. You will see the sauce transform from a pale cream color to a rich, medium brown as it thickens.
Season with salt and black pepper to taste. If the consistency feels too thin, continue to reduce for another minute or two until it lightly coats the back of a spoon.
Strain the sauce through a fine-mesh sieve into a small bowl to remove the shallots. If you have significantly more than 100ml (3.5 oz) of liquid, return it to the pan to reduce further. Use a rubber spatula to ensure no sauce is wasted.
Serve the jus sparingly, allowing about 1.5 to 2 tablespoons per person. Drizzle it directly over or around your protein, such as steak, roast beef, or crispy pork belly, for a restaurant-style presentation.
For the best results, use a high-quality or homemade beef stock, as the flavor becomes very concentrated during reduction. If you don't have vermouth, a dry white wine or dry sherry can be used as a substitute. This jus can be made ahead of time and gently reheated before serving.
