Sweet Tomato Jam is a thick, sticky jam prepared with summer fresh tomatoes, onions, and seasonings. Move over ketchup; there’s a new condiment in town!

Tomato and jam – not two words you hear together normally. But, this sweet and sticky treat is so far removed from being normal! It’s a new condiment that can replace ketchup wherever you normally use ketchup. It’s thick, sweet, tart, smoky, and even a little spicy.
This recipe makes a small batch of Sweet Tomato Jam. You can easily double the recipe if you want more. And, because I’ve been asked many times already, I have not tried canning this recipe. I think it’s best to stick to small batches for two reasons. First, it’s easy to make, even though it does take some patience. And, secondly, you’ll want this jam to be as fresh as possible.
WASHING THE TOMATOES
It’s very important to wash the tomatoes well before getting started. Can I share a secret with you? I wash all of my produce in lukewarm water and whatever dish detergent I have on hand. I’m serious!

You can spend nearly $8 for a small bottle of produce “soap” at the grocery store, and if you took the time to compare the list of ingredients to a dish detergent, there’s very little difference.
Add the tomatoes to a large bowl with a drop or two of dish detergent. Fill the bowl with cool water. Gently swish the tomatoes around, creating a lather. Massage the tomatoes in your hands under running water until all of the soap is completely removed. Transfer to a clean bowl until ready to use.
GOOD THINGS COME TO THOSE WHO WAIT
As I previously mentioned, Sweet Tomato Jam takes time. When simmering the mixture, think about how the tomato jam will look when it has cooled. If, in your mind, it does not look like it will have the consistency of a fruit jam, let the mixture continue to simmer.

It’s important to simmer the mixture. Don’t ever let the mixture come to a boil, because it will burn. The addition of the sugar to the jam will easily burn and you don’t want burned black bits floating around in your jam! Continue to stir often. Babysit it. Love it.
Depending on how much moisture is in your tomatoes, time time it takes to get to jam stage can vary. I’ve prepared this jam a few times. And, even though I always use the same type of tomato, the time it takes to finish the jam is always different. Give yourself anywhere from two to three hours.
FINISHING UP
Once your jam is thick, it’s time to transfer it to a jar. Please, please, please be careful! This jam is like lava. It will seriously burn you if it gets onto your skin.
Use a clean mason jar with a new seal. Wash the mason jar, seal, and ring with hot, soapy water. Rinse the jar under hot running water to get rid of the soap residue. Using a canning funnel, ladle the jam into the jar. Place the lid on the jar and set it aside for two hours.

This will allow the jam to cool down before transferring it to the fridge. In some cases, you will hear a popping sound. This is normal and may or may not occur. Once the jam cools, and the air contracts, there will be a pulling force on the sealing disc. The popping sound is the jar sealing. This is a good thing. Keep the jam refrigerated. It will last for two months in the fridge.
