How to Make It
Place a colander in a 2-quart glass measure or medium bowl. Place tomatoes in colander; sprinkle salt over tomatoes. Cover with plastic wrap; refrigerate 12 hours. Discard liquid.
Place cloves, allspice, and cinnamon on a small piece of cheesecloth. Gather edges of cheesecloth together; tie with string to make a pouch.
Combine the tomatoes, cheesecloth pouch, sugar, and remaining ingredients in a large Dutch oven. Bring to a simmer over medium heat; cook, uncovered, 1 1/2 hours, stirring frequently. Discard the cheesecloth pouch.
Note: Pioneer Ketchup can be stored in an airtight container in your refrigerator for up to 1 month.
