How to Make It
Preheat the oven to 450°. Arrange the apples in a large roasting pan. Pour the apple juice over the apples and bake for 30 minutes, or until tender and browned. Lower the oven to 350°.
Using a fork or potato masher, thoroughly mash the apples in the roasting pan. Bake the apple puree, stirring occasionally, for 1 1/2 to 1 3/4 hours, or until very thick and deeply browned. Scrape into a bowl and let cool. Serve at room temperature or chilled.
Make Ahead: The apple butter can be refrigerated for up to 3 days.
