Red Wine Reduction Sauce

Instructions

1. Sauté the aromatics
   In a medium saucepan over medium heat, melt 1 tablespoon of butter. Add the minced shallots and cook until soft and translucent, about 3-4 minutes. Add the garlic and cook for an additional 30 seconds until fragrant, being careful not to burn it.
2. Add the wine and reduce
   Pour in the red wine, increase the heat to medium-high, and bring to a simmer. Allow the wine to reduce by half, about 10-12 minutes. This concentrates the flavor and evaporates the alcohol.
3. Incorporate remaining ingredients
   Add the beef stock, thyme sprigs, bay leaf, tomato paste, and black pepper. Stir to combine and bring back to a simmer. Continue to cook, reducing the liquid by about two-thirds until it reaches a slightly syrupy consistency, about 10-15 minutes.
4. Strain and season
   Remove the thyme sprigs and bay leaf. For a smoother sauce, strain the reduction through a fine-mesh sieve into a clean saucepan, pressing on the solids to extract maximum flavor. Return to low heat and season with salt to taste.
5. Finish the sauce
   Stir in the balsamic vinegar for brightness. If using flour for a thicker sauce, mix it with the remaining tablespoon of butter to form a paste (beurre manié), then whisk small amounts into the sauce until desired consistency is reached. Finally, swirl in the remaining butter off heat to add richness and shine (monte au beurre).
6. Serve immediately
   The sauce is best served immediately while warm. Drizzle it over steak, lamb, or roasted vegetables. If not using right away, keep warm or reheat gently when ready to serve, as the sauce may thicken upon standing.
