I’ve been making variations on this recipe for nearly 20 years now. This is the best version of this sauce to date .
It’s especially timely now while tomatoes are at their most plentiful, and an ideal way to use up all the skins and cores generated in canning.
If you are canning/skinning a full bushel of tomatoes, using these trimmings would make several jars of ketchup even without using any whole tomatoes, which of course you may also do.
It’s also very nice with green tomatoes, green apples, and cider vinegar, with a larger percentage of cloves to peppercorns, and intended to be used with pork.
