Recipe Notes

**Note – you can also use fresh tomatoes to make this ketchup – Use approximately 4 pounds of paste tomatoes -peel and cut into quarters. Add 1/4 of the tomatoes to a large stockpot, heat to a boil – using a potato smasher to crush the tomatoes. Once a boil has been reached, add the remaining tomatoes. Return to a low boil, stirring often, for 5 minutes. Add to crockpot and proceed to number 2.
