Method
Place the whole black peppercorns in a mortar and pestle and crush them roughly. Avoid turning them into a fine powder, as you want distinct textural bursts of pepper.
In a skillet over medium heat, melt the unsalted butter. Add the minced shallot and cook until softened and translucent, stirring frequently to prevent browning.
Add the crushed black peppercorns to the skillet and cook for an additional minute to toast the spices and release their essential oils.
Remove the skillet from the heat briefly. Pour in the cognac to deglaze the pan, scraping up any browned bits from the bottom. Return to heat and cook until the alcohol smell dissipates and the liquid is mostly evaporated.
Pour in the beef stock. Increase the heat slightly and boil until the liquid is reduced by half, concentrating the savory flavor of the base.
Lower the heat to maintain a gentle simmer around 90°C/195°F. Whisk in the heavy cream and simmer until the sauce thickens enough to heavily coat the back of a spoon.
Remove from heat. Taste the sauce and season with kosher salt as needed. Let it rest for a few minutes off the heat to stabilize before serving.
Chef's Notes
- Always crush peppercorns manually rather than using a standard pepper grinder. A grinder produces fine dust that makes the sauce visually grey and texturally gritty, whereas roughly crushed peppercorns provide delightful bursts of flavor without overwhelming the palate.
- The consistency of a classic cream sauce is evaluated using the nappe test. When the sauce coats the back of a spoon, swipe a finger across the metal. If the line remains distinct without weeping, the sauce has reached perfect viscosity.
- If you are serving this sauce with a pan-seared steak, make the sauce directly in the same skillet after resting the meat. The fond (browned bits) left from the beef will provide an incredible depth of flavor that cannot be replicated in a clean pan.
- Cognac provides the most authentic and complex sweetness, but armagnac or a good quality brandy work wonderfully. Avoid using cooking wine or heavily sweetened liqueurs.
Storage
Refrigerator: 4 days — Store in an airtight container. Press a piece of plastic wrap directly against the surface of the sauce to prevent a skin from forming.
Reheating: Reheat gently in a saucepan over low heat, whisking constantly. Do not let it boil, or the sauce may break.
