Preparation Preheat oven to 450°F. Butter 9-inch cast-iron skillet. Heat over medium-high heat. Add pears, rounded side down, to skillet and cook until golden brown, about 3 minutes per side. Spoon syrup over pears. Transfer skillet to oven and roast pears until tender, turning and basting once, about 10 minutes. Remove skillet from oven and bring pear mixture to boil over high heat; boil until almost all juices have evaporated, about 2 minutes. Cool to room temperature. Reduce oven temperature to 350°F.
