1 . Stage

Set an oven rack about 6 inches from the heat source and preheat the oven's broiler. Line a baking sheet with aluminum foil. Place Anaheim pepper onto the prepared baking sheet.

Add peppers to the simmering tomato juice, along with onion and celery. Simmer for 1 hour.

Add apple cider vinegar, brown sugar, mustard, cinnamon, salt, cloves, allspice, and salt. Simmer for 1 more hour, or until desired thickness. Puree ketchup with an immersion blender until smooth.
