Directions:

1. Combine all ingredients in a large saucepan.
2. Bring to a boil, then reduce heat to moderately-low.

4. Stir often and be sure ketchup doesn't scorch.
5. Adjust seasonings and add more sugar or vinegar if you wish.
6. Continue to simmer if not thickened.
7. Process with a food mill using a medium size disc (approx. 5 mm). Pour ketchup into three sterilized half-pint jars, leaving 1/2-inch headspace.
8. The pulp and sauce should be about the consistency of a thick tomato sauce.
9. If not, return to the pot over medium heat until thickened.

14. Ketchup will keep well for up to 6 months.
