Ingredients:
- 15 lbs Ripe Paste Tomatoes (Roma or Amish Paste)
- 2 Large White Onions, roughly chopped
- 3 Cloves Garlic, smashed
- 1.5 tsp Celery Salt
- 1 tsp Whole Cloves
- 1 tsp Whole Allspice
- 1 stick Cinnamon
- 1.5 tsp Onion Powder
- 0.5 tsp Cayenne Pepper
- 2 cups Apple Cider Vinegar (5% acidity)
- 1 cup Distilled White Vinegar (5% acidity)
- 1.5 cups Granulated Sugar
- 2 tbsp Sea Salt
Instructions:
- Wash and quarter the tomatoes. In a large heavy-bottomed pot, combine tomatoes, onions, and garlic. Simmer over medium heat for 20 minutes until softened.
- Process the mixture through a food mill with a fine screen or a high-speed blender, then strain through a fine-mesh sieve to remove skins and seeds for a silky texture.
- Return the strained tomato liquid to the pot. Place the whole cloves, allspice, and cinnamon stick in a spice bag or cheesecloth and add to the pot.
- Add the apple cider vinegar, white vinegar, sugar, sea salt, celery salt, onion powder, and cayenne pepper.
- Simmer uncovered over medium-low heat for approximately 2.5 to 3 hours, stirring occasionally to prevent scorching, until the volume is reduced by half and the desired 'slow pour' thickness is achieved.
- Remove the spice bag. Ladle the hot ketchup into sterilized pint jars, leaving 1/2-inch headspace. Process in a boiling water bath canner for 15 minutes to ensure shelf stability.
