Ingredients:
- 1 pound (450g) venison backstrap, trimmed of silver skin
- 1 tablespoon (15ml) olive oil
- 1 tablespoon (14g) unsalted butter
- 1 teaspoon (5g) freshly ground black pepper
- 1 teaspoon (6g) kosher salt
- 1 tablespoon (15ml) olive oil
- 1 shallot, minced (about 1/4 cup)
- 1 clove garlic, minced
- 1/2 cup (120ml) port wine
- 1/2 cup (120ml) beef broth
- 1/2 cup (75g) fresh blackberries
- 1 tablespoon (15ml) balsamic vinegar
- 1 teaspoon (5g) brown sugar (optional)
- 1 tablespoon (14g) unsalted butter, cold, cut into cubes
- Pinch of salt and black pepper to taste
Instructions:
- Pat the venison backstrap dry with paper towels. Season generously with salt and pepper. Allow the venison to sit at room temperature for 30 minutes.
- Heat olive oil and butter in a cast iron skillet over medium-high heat until shimmering. Add the venison backstrap to the skillet and sear on all sides until a deep brown crust forms (about 3-4 minutes per side).
- Use a meat thermometer to monitor the internal temperature. Aim for 130-135°F (54-57°C) for medium-rare, 135-140°F (57-60°C) for medium.
- Remove the venison from the skillet and transfer to a cutting board. Tent loosely with foil and let rest for at least 10 minutes before slicing.
- While the venison rests, heat olive oil in a small saucepan over medium heat. Sauté the shallot and garlic until softened and fragrant.
- Pour in the port wine and beef broth. Bring to a simmer and reduce by half, scraping up any browned bits from the bottom of the pan.
- Stir in the blackberries and balsamic vinegar. Simmer for a few minutes until the berries soften and release their juices. Add the brown sugar if needed.
- Remove the saucepan from the heat and whisk in the cold butter until melted and the sauce is glossy. Season with salt and pepper to taste.
- Slice the rested venison backstrap against the grain. Fan the slices out on plates and drizzle generously with the blackberry-port wine reduction. Serve immediately.
