Tomato Jam
This jam is so delicious that I couldn’t wait to post this and I’m doing it while I make my SECOND batch. In the past, I’ve made tomato butter (yuck) and tomato jelly (okay) but this jam is amazing. I can see myself putting in on everything!!
I found this tomato jam recipe on Food in Jars while surfing canning blogs. It sounded good and different from my previous sweet tomato experiments. I abandoned my plans of making zucchini marmalade (for today) and got straight to work cutting up tomatoes. I love the fact that you don’t have to remove the seeds or the skin…that makes it much easier and Marisa is right…it adds to the texture and taste. I’m thinking of putting it on eggs, toast, sausages, hamburgers or just eating it straight from the jar. Now, I’m thinking I better make another batch or two!
RECIPE FOR TOMATO JAM (thank-you Food in Jars):
- 5 pounds tomatoes, finely chopped

- 3 1/2 cups sugar
- 8 tablespoons lime juice
- 2 teaspoons freshly grated ginger
- 1 teaspoon cinnamon
- 1/2 teaspoon ground cloves
- 1 tablespoon salt
- 1 tablespoon red chili flakes
- Combine all ingredients in a large stainless steel saucepan (non-reactive pot). Bring to a boil and then reduce temperature to a simmer. Stirring regularly, simmer the jam uncovered until it reduces by about half. This will take between 1 and 1 1/2 hours, depending on how high you keep your heat.

- When the jam has reached the gel stage remove from heat.
- Ladle hot jam into sterilized 250mL jars leaving 1/4″ headspace. Remove air bubbles and adjust headspace, if necessary, by adding hot jam. Wipe rim. Center lid on jar. Screw band down until resistance is met, then increase to fingertip-tight.
- Place jars in canner, ensuring they are completely covered with water, bring to a boil and process in hot water bath for 20 minutes. Remove canner lid. Wait 5 minutes, then remove jars, cool, label and store.
Put up Total:
- 2 x 500mL Fancy mason jars (1 vintage Kerr jar)
- 3 x 250mL wide mouth mason jars
- 5 x 250mL regular mouth mason jars




Tomato Jam? Now that I would have never thought about.
Awesome idea and thanks
It is so good. I am actually boiling down a double batch right now. It has a sweetness to it as well as a kick at the end from the chili pepper flakes. MmmmMMMgood! The texture is nice too.
I too, am a fan of the tomato jam. I found your website via Food in Jars and am just thrilled! I’m trying the Spiced Beer Jelly later, and right now am looking over your other recipes to see what will be next. Thanks!!!
I made this jam this past summer and fell head over heels for it. And so did every single person I gae a jar too! I will make this every year for the next ever and ever.
Oh dear god, I’m in love. I made a batch of this last night, and I’m blown away. I was canning late into the night and the first thing I did this morning was put some inside my omelet. I think I might even have dreamt about it.
A canning question for you though. It was late last night and being the newbie canner I am, I don’t quite have the process down yet, so I totally forgot to eliminate air bubbles. With as thick and chunky as this jam is, I have large bubbles in every jar. Is this something I should worry about? I have a perfect seal on each jar. Is it ok to leave it hte way it is, or should I pop them open, boil the jam and process it again? I’m planning on giving a jar or two of this stuff away at christmas (if it lasts that long!) and poisoning my friends would not be a good thing.
Been there…done that! No…I wouldn’t worry as long as the seal is good. Reprocessing is unnecessary and may change the consistency. We were the same with our first batch of jam (totally forgot about the air bubbles). It’s recommended to move them because these pockets of air can create mold and spoil the contents but our jam (with bubbles) was fine and we enjoyed every jar even after a year. We still will get air bubbles in some of our preserves despite our efforts to remove them (some fruits contain more air in their cells). I doubt this tomato deliciousness will last until Christmas time but you will know with each jar whether or not it is okay. Discard, if the seals are broken or there is mold on top (those are really the only things you have to worry about with this one).
Thanks. That’s 2 out of 2 responses that say just leave it. So I will. I put the worst offender in the fridge and plan on opening that next. And you’re right, I doubt it will last that long. I’m really hoping to see tomatoes down to 39 cents/lb again soon so I can do a couple more batches atleast. And I really want to try a version seasoned with chinese 5 spice for an asian flair, or my mom’s secret recipe tandoori spice rub for an indian twist. And I need to get my blog back up and running so I can share this jammy goodness with the world!
I grew my own tomatoes this year JUST to try this recipe! However, I don’t have a canner – will it work by just doing the hot water bath? Thank you for your time in posting. I LOVE your blog!

Home grown tomatoes…WOW!! You’re tomato jam is going to rock!
Sorry, for any confusion by using the word “canner” I meant hot water bath canning…not pressure canner. I’ve changed the wording on the recipe…thanks:>)
We’d love to hear how your tomato jam turns out…I know it’s going to be amazing. It truly is one of our favorites. We did 6 batches last year and are down to the last jar. I’m hoping to make at least 6 more batches for this year.
Just thought I’d wander back and comment again since I was sharing this recipe with a friend today. I made my first batch of this in June – my second ever attempt at canning. Since then I’ve made a second batch and right now have 25 lbs of roma’s in my kitchen at the moment, waiting for me to get moving today. I imagine there will be a third batch cooling on the kitchen counter before the day is over. (along with hopefully 8 more jars of crushed tomatoes) I just want to say thanks so much for providing me with that ‘gateway drug’ so to speak that got me hooked on canning. My pantry is slowly filling up and todays efforts will bring my totals to about 40 jars of food lining my shelves. Not too shabby for a newbie, if I say so myself! And with some of the money I’ll save this year on buying spaghetti sauce (a staple for me) I can justify the cost of a pressure canner before next summer. Then I’ll really go to town!
That is so awesome! Canning sure is addictive…or at least that is what we’ve found. There is so much satisfaction in preserving your own food and the taste is impossible to beat. Later this year we are going to do a post on fellow canners pantries…maybe you’d like to share a photo or some words of encouragement for other canners?
Keep up the great work! We’re off to stem 10lbs of elderberries and husk about 60lbs of tomitillos.
