Divide the butter and honey between 2 large skillets and bring to a boil. Cook over high heat, stirring occasionally, until lightly golden, about 4 minutes. Add half of the pears to each skillet, cut side down, and cook, turning occasionally, until golden and beginning to caramelize, about 12 minutes. Add 3/4 cup of the reserved pear poaching liquid to each skillet and cook over moderate heat, turning and basting the pears, until the liquid reduces to a thick syrup, about 8 minutes. Using a slotted spoon, transfer the pears to a platter. Stir 2 tablespoons of the poaching liquid into each skillet to thin the syrup. Pour the sauce over the pears.
