Heat oven to 350 degrees. Butter baking dish and sprinkle with granulated sugar. Add cherries to the dish. Make batter: Sift flour into a bowl with salt, stir in sugar and make a well in the center. Add eggs to well and whisk them until mixed. Whisk in half the milk, gradually drawing in the flour. Stir in remaining milk to make a smooth batter. Pour batter over cherries and bake in heated oven until clafoutis is done, 35-45 minutes. Sprinkle brandy or kirsch over hot pudding and serve hot or warm. The clafoutis will sink slightly as it cools. Sprinkle with confectioner's sugar just before serving.
