Chef John'S Apple Butter

1. 1

   Place apple pieces into a large slow cooker. Add white sugar, brown sugar, salt, cinnamon, nutmeg, allspice, and vinegar. Add a splash of water and mix well.

2. 2

   Cover and cook on High until apples are starting to soften and release liquid, 1 to 2 hours. Reduce heat to Low and cook, uncovered, until all the apple flesh is dissolved, 5 to 6 hours. Stir occasionally.

3. 3

   Puree using an immersion blender until smooth. Continue cooking, stirring occasionally, until darkened and thick, about 4 hours more. Pass apple butter through a strainer if desired. Seal in a glass container and refrigerate until cool.
