Preheat oven to 200 degrees F (95 degrees C). In a small bowl, combine crushed thyme, sage, salt, and pepper. Rub evenly over pork chops.
Melt butter and olive oil in a nonstick skillet. Cook pork chops for 4 to 5 minutes on each side, turning once. Remove from skillet and keep warm in preheated oven.
In the skillet, combine raspberry jam, orange juice, and vinegar. Bring to a boil, and cook for 2 to 3 minutes, or until sauce is reduced to desired consistency (sauce will thicken as it cools). Spoon sauce in a pool onto a serving plate, and top with pork chops. Garnish with sprigs of thyme.
