Grilled Pork Tenderloin with Blackberry Sauce

1 . Stage

Mix vinegar, sugar, salt, paprika, mustard, and pepper together; marinate pork in the mixture for up to 4 hours.

2 . Stage

Heat a medium saucepan over high heat and add olive oil. Stir in garlic, shallots, carrot, and celery; reduce heat to medium-high and saute until vegetables begin to brown and caramelize, about 5 minutes. Add Chateau Ste. Michelle Cabernet Sauvignon to deglaze the pan, stirring well.

3 . Stage

Stir in stock, blackberries, jam, and balsamic vinegar. Bring the mixture to a boil, then reduce the heat to medium and continue cooking until the liquid is reduced by half, about 30 minutes.

4 . Stage

Strain sauce and return to pan. Bring sauce to a boil over high heat; reduce heat to medium. Cook until sauce is reduced by half and thickened, about 5 minutes more. Season to taste with espresso, salt, and pepper.

5 . Stage

Heat grill to medium heat. Brush the pork with 2 tablespoons olive oil and place on grill. Cook for about 15 minutes, turning each side 90 degrees to make a crosshatch pattern. An instant-read thermometer inserted into the center should read at least 150 to 155 degrees F.

6 . Stage

Transfer pork to cutting board and let rest 8 to 10 minutes. Slice and serve with blackberry sauce.
