In a large Dutch oven, heat 1 cup sugar and 3 tablespoons water over medium heat, without stirring, until sugar is golden brown. (The darker the color, the richer the flavor.) Gradually add cider; cook until sugar dissolves. Add cinnamon stick, and bring to a gentle boil; reduce heat to low, and cook for 15 minutes.
Heat a medium cast-iron skillet over medium-high heat until hot.
Dip cut sides of apple halves in remaining 1⁄4 cup sugar; place, cut side down, in skillet. Cook until lightly browned, 1 to 2 minutes. Float apples in cider to serve.
