How to Make Chipotle Ketchup

• 1). Cook tomato halves, onion and chipotle powder over medium heat with a little bit of olive oil until soft. Allow to cool completely.
  
  
• 2). Puree the tomatoes, onions and chipotle powder in batches in a blender. Set aside.
  
  
• 3). Warm the sugar in a large pot, stirring constantly. Do not let the sugar turn to caramel. When the sugar is warm but not melted, add the tomato and onion puree mixture, as well as the vinegars, and reduce the heat. Simmer for about 30 minutes.
  
  
• 4). Add cayenne pepper, peppercorns, allspice, dry mustard, cinnamon, cloves and salt to taste. Stir in and blend well. Ketchup should be thick by now.
  
  
• 5). Strain ketchup through a fine sieve or cheesecloth into a large plastic bowl. Allow ketchup to cool to room temperature before storing.
  
  
• 6). Store ketchup in air-tight containers and refrigerate.
