Erin SheehanWe’ve make our own mustard, relish and pickles, but I’ve never tried making ketchup. Our bumper tomato crop this year made me decide to try canning ketchup for the first time. Most ketchup brands at the grocery store have high fructose corn syrup, which we try to avoid. I figured why not try to make my own and see if I can get away from the commercial varieties for good. As it turns out, making ketchup is pretty easy and I was blown away by how much I love the taste! It came out so well I wanted to just eat it right out of the pot. Here’s a simple recipe I modified from my Ball Canning Book. Let me know if you give it a try.


Home Canned Ketchup

12 pounds cored, peeled, pureed paste tomatoes
1  1/2 cups cider vinegar
3/4 cup white sugar
1 hot pepper (optional)
2 medium sized yellow onions
1  1/2 tablespoons celery seeds
2 teaspoons whole cloves
1 teaspoon whole allspice
1 broken cinnamon stick
2 tablespoons canning salt

Heat tomatoes, vinegar and sugar in a large stainless steel pot. While tomatoes are warming up, puree pepper and onions together in the food processor. Use some of the liquid from the tomatoes to make sure you get it really smooth. Add to tomato mixture and bring to a boil. Reduce heat to a simmer.

Tie up a piece of cheesecloth with the celery seeds, cloves, allspice and cinnamon stick inside. Hang off edge of pot with your tomatoes. Add salt.

Simmer until thickened. You want it as close to the consistency of commercial ketchup as possible. This can take as long as 4 to 5 hours. You will have to stir fairly frequently. Remove cheesecloth and spices and scrape it as clean as you can.

Hi Barbara - thanks for the question. Paste tomatoes are any variety grown specifically for canning, as opposed to "slicers," which are grown more for eating. Paste varieties have less liquid and seeds, tending to be very dense. We grow "Pony Express" from Harris. You can probably find paste tomatoes by the 1/2 bushel through a local farmstand.

City girl here. Are "paste tomatoes" tomatoes that you make tomato paste with or are you referring to tomato paste itself?

Erin, I have made catsup in the past but not for a long time. It was so good that it hardly made it through the next month. It was almost like steak sauce. The simmering process I went through took a long time to thicken the catsup so I just never did it again. Since the tomato glut comes at a time when the temperatures soar to above 90 degrees outside, I can't see the practicality of heating up the house with simmering catsup. If I was to do it again, I would freeze the tomatoes and make the catsup during the cold months of the year when heating up the kitchen would be beneficial. ***** Have a great catsup making day.
