Even if you’ve never canned tomatoes before, you should try making this Green Tomato Ketchup Canning recipe. It’s not as hard as you think!  After all, there’s nothing like enjoying the benefits of your garden year round by canning your tomatoes.

Since I was new to canning tomatoes, I decided to make green ketchup since it was easy to do. I was overjoyed at how well my first batch of green ketchup turned out. Green Tomato Ketchup is very sweet and mild, almost like an apple sauce rather than a red tomato ketchup. I’ve tried it everything from eggs to fish sticks to sweet potato fries. Terrific!

For food safety, it’s very important that you add bottled lemon juice to this Green Tomato Ketchup recipe to give it enough acidity to avoid any issues with Clostridium botulinum bacteria, which is a deadly neurotoxin. You can read about it on this PDF from the University of Wisconsin.

They recommend 2 tablespoons of bottled lemon juice per quart. Since my Green Tomato Ketchup recipe makes 2 quarts, I added 4 tablespoons.

Due to my food sensitivities to honey, I used agave nectar to sweeten my Green Tomato Ketchup recipe. Feel free to use honey if you like.

Canning equipment needed to make Green Tomato Ketchup

Don’t have any canning equipment? The Ball Enamel Water Bath Canner comes with a 21-quart capacity enamel waterbath canner, chrome plated rack and Ball Utensil Set.

Already have a large stock pot? Then you might want to purchase just the Ball Utensil Set and the Ball Home Canning Discovery Kit, which comes with a polypropylene rack and lifter, some jars, and a recipe book. I have this lifter and it works great!

I also recommend Ball Dissolvable Labels. These are terrific for canned green ketchup as well as labeling jars for gifts like homemade taco seasoning or brown sugar scrub. Super easy to get off during washing.

How to Make Green Tomato Ketchup

Green Tomato Ketchup

Adapted from About.com Southern Food’s recipe

Ingredients

  • 6 pounds green tomatoes
  • 3 pounds onions
  • 2 teaspoons ground black pepper
  • 1 tablespoon ground dry mustard
  • 1 teaspoon Worcestershire sauce
  • 2 teaspoons mixed pickling spices
  • 2 cups cider vinegar
  • 2 tablespoons bottled lemon juice (do not used fresh juice as it's not acidic enough)
  • 3/4 to 1 cup agave nectar (I used raw agave. Any type is fine.)

Directions

  1. Slice green tomatoes and onions. Place in a large pot with pepper, mustard, and Worcestershire sauce.
  2. Put the mixed pickling spices in a small cheesecloth bag and add to the tomato mixture.
  3. Pour cider over mixture.
  4. Cook for four to six hours over very low heat, stirring occasionally.
  5. Remove bag of pickling spices.
  6. Puree mixture with a wand blender or in a food processor or blender.
  7. Strain tomato mixture through a mesh strainer.
  8. Return to pot and bring to boil.
  9. Add lemon juice and 3/4 cup of agave and stir until dissolved. Using a clean spoon, take a taste. If you feel the ketchup is sweet enough, stop. If not, add another 1/4 cup of agave nectar. Remember to use a clean spoon every time you taste test.
  10. Immediately fill six sterilized jelly jars with green tomato ketchup, leaving 1/4-inch head space.
  11. Wipe the jar tops and threads clean with a clean paper towel. Place hot sealing lids on the jars and apply the screw on rings loosely.
  12. Process in boiling water bath in a deep canning pot for 5 minutes, adjusting for altitude.
  13. Remove the jars and cool completely. Tighten the jar screw rings to complete the sealing process.
  14. After the jars of green tomato ketchup cool, check seals by pressing middle of lid with finger. If lid springs back, your green tomato ketchup didn’t seal and must be refrigerated.
  15. Let jars of green tomato ketchup stand at room temperature 24 hours. Don’t forget to apply a dated label!
  16. Store unopened product in a cool dry place up to one year. Refrigerate green tomato ketchup after opening.
