1. Preheat oven to 375º. Use a small knife to remove the apple cores, cutting into the center of the apples, but leaving bottom intact to form a cavity. Peel the top half of the apples.
2. In a small bowl, mix walnuts, honey, and 1/2 teaspoon of the cinnamon. Use a small spoon to stuff apples with filling on top.
3. Places stuffed apples in a medium-size, shallow roasting dish or baking pan (leaving enough room so the apples don't touch), and pour the cider or water over them.
4. Mix sugar and remaining cinnamon; sprinkle over tops of apples. Bake for 18 to 20 minutes, basting once or twice, or until apples are soft. (Warning: Apples will be very hot, let them stand for a few minutes to cool.) Serve warm.
How kids can help: Mix walnuts, honey, and cinnamon; stuff apples; place apples in pan. Mix cinnamon and sugar, and sprinkle over apples.
