Sausage sizzle has become a symbolic election day food in Australia. These grilled beef sausages topped with grilled onions and homemade ketchup are served on simple white bread, just like you are likely to find waiting for you outside the election centers in Australia, after you cast your vote.
Combine all of the ingredients except the sugar and vinegar into a sauce pot and bring to a boil, then reduce heat to simmer.
Simmer the sauce for 1 hour.
Add in the sugar and vinegar and return to a boil for about a minute, then again reduce heat to a simmer. Continue to simmer until it reaches your desired consistency, stirring frequently. Depending on the amount of liquid in your tomatoes, this can take 30 minutes to an hour.
Remove the cinnamon stick, then blend the sauce to a smooth consistency in a blender or with an immersion blender.
