Crème de cassis and white wine make up the fruity apéritif known as kir royale. For this recipe, the black currant liqueur gives the pears a berry richness and a lush mahogany color.
Place oven rack in lower third of oven; preheat to 375 degrees F.
Set pear halves cut-side down in a baking dish. Pour creme de cassis and lemon juice over the top. Sprinkle with sugar and dot with butter. Bake, uncovered, basting occasionally with the pan juices, until the pears are tender and the juices have thickened slightly, about 45 minutes. Let cool briefly before serving.
