Old fashioned Ketchup

Ingredients

2 tablespoons olive oil
1 medium onion, chopped medium
1 clove garlic, minced
1 28-oz can tomato puree
1/2 cup fire roasted diced tomatoes
1/2 cup packed dark brown sugar
1/3 cup cider vinegar
¼ cup of molasses
1 tablespoon tomato paste
1/2 teaspoon kosher salt
1/2 teaspoon ground mustard
1/8 teaspoon ground cloves
1/8 teaspoon cinnamon
1/8 teaspoon allspice
1/8 teaspoon cayenne pepper

Directions

Heat oil in a medium saucepan over medium heat until shimmering. Add in the onion and cook, stirring occasionally, until softened but not browned.  Add in the garlic and stir until fragrant, about 30 seconds. Add the tomato puree, diced tomatoes, brown sugar, vinegar, molasses, tomato paste, salt, mustard, cloves, cinnamon, allspice, and cayenne pepper and stir to combine. Bring to a boil, then reduce heat to low and simmer, stirring occasionally, until thickened to the consistency of ketchup, 45 to 60 minutes. Puree in blender and strain into returnable beer bottles.
