Combine all ingredients in a saucepan whisk smooth and bring to a boil. Reduce heat to simmer for 25 minutes (cooking it gets rid of the raw tomato flavor as ingredients mingle together).
Remove from heat and cover until cool. Refrigerate and enjoy.
Skip the light corn syrup and go with all white granulated sugar (1/3 to 1/2 cup will do it, to make ketchup similar to 'Simply Heinz').
Evaporated cane juice - instead of light corn syrup and / or granulated white sugar. Evaporated cane juice is a less-processed sugar. It has a more complex flavor and comes in light brown granules. Evaporated cane juice is not as dark or as strong molasses-tasting as light brown sugar.
