Easy Homemade Ketchup

I noticed the other day that I am low on ketchup but kept putting off buying it until I needed it. My pantry is a bit stuffed and I didn’t want to add anything that would have to sit on the shelf unused.

Then Papa Satyr brought in a pound of date-sized Roma tomatoes, ripe or near ripe, that he wanted to save from the tomato bugs. Then, he did this again and again. Suddenly I had three pounds of tomatoes to use.

I also had a new canning pot I had picked up in the spring in anticipation of needing to preserve things for later use. Last year, I had just used a pot and a pair of tongs  and I can dangerously close to scalding myself a couple of times, so decided to get the right set up.

What to do with my tomatoes?  I could stew them for later use, I supposed, but I already have a fair amount of store-bought canned diced, stewed, and crushed tomatoes because I purchase them in 12-packs.  I make a lot of tomato based dishes.

<Light bulb appears over my head.>

I could make ketchup. So, first I went over to Wikipedia for a cursory tour of the history of ketchup, armed with my knowledge they were not always made with tomatoes, but started as an Eastern fish sauce. Not that I intended such a thing, but a girl likes to know what came before.
Somewhere in the 1800s, tomato became the favorite, displacing oysters, mussels, mushrooms, and walnuts as the main ingredient of various catsups, though I am considering making a small batch of the walnut variety in the future.

As I wanted to get back to the roots of tomato ketchup, and because I have an obsession with the founding fathers, I turned to The Virginia Housewife by Mary Randolph (relative of Thomas Jefferson).

Her recipe called for a peck of tomatoes, salt, half a pint of chopped onions, a quarter ounce of mace, and whole black pepper. I like my ketchup sweet and tangy and like the modern improvements of additional spicing, plus I changed the process to do in my slow cooker because I am lazy, but it all started with Mary Randolph.


My was made of baby tomatoes so I skipped strainer the seeds and skins, instead just blending them in. That is up to your preference. Then, I canned it. Yay.

I came to my own rescue this morning when I wanted to serve my leftover potato pancakes but Papa Satyr had eaten all the sour cream the night before with the tamales that will feature in a subsequent post. Silly Hattie…I know better than to let him make his own plate.
