01 - Place apples, granulated sugar, light brown sugar, and apple cider or water in a large, heavy-bottomed pot. Stir to mix evenly.
02 - Heat over medium, stirring occasionally, until apples soften and begin breaking down, approximately 20 to 30 minutes.
03 - Remove from heat and blend with an immersion blender or standard blender in batches until the texture is very smooth.
04 - Return puree to pot and stir in cinnamon, cloves, allspice, nutmeg, salt, and fresh lemon juice uniformly.
05 - Simmer uncovered on low heat, stirring frequently to prevent sticking, until the mixture thickens, darkens, and holds its shape on a spoon, about 1.5 hours.
06 - Taste and fine-tune the spice blend or sweetness as preferred.
07 - Allow to cool slightly, then transfer to sterilized jars. Refrigerate for up to three weeks or process for long-term storage.
