The first thing I made in my crock pot is this "All-Day Apple Butter", from this cookbook my parents gave me called, "Fresh From The Vegetarian Slow Cooker". I've been wanting to make crock-pot apple butter for so long, ever since my old, super crappy crock-pot burned a first attempt a few years ago. Burned apples are just sad. So, I went for it right away with my shiny and new crock-pot. Apple butter is such a comfort food, so of course I want to eat it in mass quantity. Also, it makes a delicious gift, which is always helpful this time of year. I highly recommend this fantastic recipe.
3 pounds cooking apples, such as Granny Smith, Rome Beauty or Gala, cored, left unreeled, and cut into eighths
3/4 cup firmly packed light brown sugar
3/4 cup apple juice
Juice of 1 lemon
1 tablespoon ground cinnamon
1 teaspoon ground allspice
1/2 teaspoon ground nutmeg
1/4 teaspoon ground ginger
1/4 ground cloves
Combine apples, brown sugar, apple juice, and lemon juice in a 4-quart slow cooker. Cover and cook on Low for 8 hours, until the apples are very soft.
Remove the lid, turn the heat setting to High, and stir in the spices. Continue to cook, uncovered, for 2 hours (I did this about 3 hours because it didn't look thick enough), stirring once about halfway through, if possible, until the mixture thickens.
Press the apples through a metal strainer into a large mixing bowl to remove the peels, or process the apples through a food mill. (I actually just used my immersion blender blend everything together, and that worked perfectly)
After cooling to room temperature, the apple butter may be stored, tightly covered, in the refrigerator in clean jars, where it will keep for several weeks.
