1In a saucepan over medium heat, melt the butter.
Add the minced garlic and sauté for about 1 minute until fragrant.
Stir in the flour and cook for another minute, stirring constantly to form a roux.
Gradually whisk in the red wine, ensuring there are no lumps.
Bring the mixture to a simmer and let it cook for about 5-7 minutes, or until the sauce has thickened to your desired consistency.
Season with black pepper and salt, adjusting to taste.
Remove from heat and serve warm over your favorite steak.
