Mise En Place - always have your ingredients in place before you begin.
Put all the ingredients in a large saucepan. Heat and continue to stir until the tomatoes start to break up. Use an immersion blender to break them apart more. Taste for seasoning, add more sugar if it's too sour, more vinegar if it's too sweet. Keep cooking until it has become quite thick. Remove the pan from the heat, and put the ketchup in a blender for the final puree. Blend it until it is a puree. Using a funnel, pour it into a nice, clean bottle and seal it.
