Green Tomato Ketchup Recipe

Green Tomato Ketchup Recipe.

It’s time to make this easy Green Tomato Ketchup if you’re overwhelmed with tomatoes from your garden.

Don't worry, it’s not as hard as you think, even if you're new to canning.

After all, there’s nothing like enjoying the benefits of your garden year round by canning your tomatoes.

Why make green tomato ketchup

While there’s nothing wrong with making tomato sauce and salads, you should try making this green tomato ketchup even if you've never canned before.

I decided to make green ketchup canning recipe since it was easy to do even though canning was intimidating.

In fact, 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. And it’s delicious!

How to make green tomato ketchup

Food safety first!

It’s very important that you add bottled lemon juice to this Green Tomato Ketchup recipe.

Do not use fresh lemon juice as it is not acidic enough.

Bottled lemon juice will give the green tomato ketchup 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.

Honey vs. agave

Due to my food sensitivities to honey, I used agave nectar to sweeten my Green Tomato Ketchup recipe. Any variety of agave is fine (light, dark, etc.)

However, you can use honey if you like, especially if you don’t feel the need to add something new to your pantry.

Some tomato canning guides and supplies to help you make green tomato tetchup

If you’re new to canning tomatoes, here are some books to help you get started!

Ball Complete Book of Canning and Preserving. I have this book on canning. It’s perfect for beginners.

Canning and Preserving for Beginners: The Essential Canning Recipes and Canning Supplies Guide is also a terrific guide.

● You can download USDA Publications on home canning at the National Center for Home Food Preservation. Best of all they’re FREE.

Canning equipment needed to make green tomato ketchup

Don’t have any canning equipment?

First, you need a large stock pot

The Granite Ware Steel/Porcelain Water-Bath Canner is a 21.5-quart capacity enamel water bath canner and chrome plated rack

Second, you need a canning kit

There are a variety of canning kits to choose from depending on how serious you want to get with your canning.

I recommend getting at kit with at least the following:

  • a lifter
  • a funnel
  • tongs

The Norpro Canning Essentials Boxed Set has everything you need to get started at a good price.

Then, buy dissolvable labels

I also recommend Ball Dissolvable Labels. I love these labels because they're super easy to get off when you've finished a jar and want to reuse it for something else.

These are terrific for canned green ketchup as well as labeling jars for gifts like homemade taco seasoning or DIY Coffee Scrub.

Don’t buy a cheaper brand because those won’t come off as easily when you wash them.

Finally, get good jars

Don’t forget to buy a case of 8-ounce Ball Jar Crystal Jelly Jars with Lids and Bands.

If you’re making Green Tomato Ketchup as a homemade gift, the small jelly jars are super adorable and perfect for gift giving.

    I’m wondering about sealing and canning this in Snapple bottles with lug caps. Any experience with that?

    Thank you!

    I tried this today, because we are expecting a freeze, and I had an abundance of green tomatoes, and am not a great fan of fried green tomatoes. I hated to see them go to waste. I think it turned out rather good. I think the problem other people had with it was that it was labeled as ketchup, and perhaps they expected it to taste that way. I had no expectation, so was pleasantly surprised that it tasted very good. I think it should be called ” green tomato condiment” instead.

    Knowing about the fine sieve would have been helpful and reduced time. This recipe way way too vinegary and I love vinegar. I didn’t even bother to can it need some tweak an could be very good. Disappointed

      Sorry this didn’t work out for you. The batch I made turned out very well – nice and sweet and not too vinegary.
      It’s based on a recipe that uses the same amount of vinegar, so I’m not sure why you had this problem.
      Also, the directions mention using a mesh strainer. It’s always a good idea to read through directions to make sure you have all the equipment you need before starting a recipe.

    I made this true to the recipe. It tasted so terrible that I did not even can it. It needs much more sweetener then this recipe recommends but I did not even bother, as the taste of the apple cider vinegar is so potent that you cannot taste anything else. I am not someone who prefers very sweetened condiments but a ketchup is expected to be sweet. I think regular vinegar would be less overwhelming. Oh well. It was a green tomato experiment.

    My turned out just liquid is this right? I thought it would be thicker, I strained it through a mesh and all the pulp was taken out just leaving liquid??

        in the directions … # 7 does say to strain ?? I have not yet made the green ketchup because it seems to me that straining will create a liquid??

          Make sure your mesh strainer isn’t too fine. You want to push it through with the back of a spoon to remove the skin and seeds but not the pulp. Straining it through too fine a mesh will take out all the pulp, which will make it just a watery liquid. If you want, you can skip this step and put the liquid in a blender and blend it to pulverize the skin, seeds, and pulp so it’s a nice thick liquid.

    Great idea for all those tomatoes that hadn’t ripened yet before the snow came. We picked them, but I wasn’t sure what I’d do with them. Thanks!
