Do you remember the recipe that made you fall in love with cooking? When my friend Colleen asked me that question, it took me about two seconds to answer. This tomato jam recipe, from The Little House Cookbook, is the first truly spectacular thing I ever made.
I still remember the day my mom and I made it.
It was the summer before I started fourth grade and it was probably right around this time of year, when our garden was giving us more tomatoes than we could eat. We picked some tomatoes that were still green and fried them, then we preserved some of the ripest ones by making the best tomato jam.
I gave a jar of it to my teacher for Christmas that winter. When we came back from break, she told the entire class how amazing it was and how she had already finished the whole jar. Being the super shy kid that I was, I was humiliated.
When she pointed out that my face was turning the same color as the jam I wanted to crawl under my desk and disappear.
I won’t lie – I might have cried.
But secretly, I loved that she loved it.
I already loved to cook, but that was the moment when I fell in love with cooking for other people. Making something that would make them smile. Or something that would remind them of summer in the middle of a very, very long New York winter.
Ingredient’s You’ll Need
- Ripe Tomatoes: For the best results, use 2 pounds of ripe plum tomatoes, with the cores removed. if you’re lucky enough to find them, it’s also delicious made with green tomatoes!
- Light Brown Sugar: Brown sugar gives the jam a richer flavor than using regular sugar. If you only have dark brown sugar, you can combine it in equal parts with white sugar.
- Lemon Juice: Lemon juice to balances the sweetness and ensure the acid levels are high enough. It’s important to use bottled lemon juice in this recipe, since the acidity is more consistent than fresh juice.
- Lemon Zest: For an a burst of citrus flavor.
- Freshly Grated Ginger: Use 1 teaspoon of grated fresh ginger for a hint of spice, or 1/4 teaspoon of ground ginger if you prefer.
- Half-Pint Canning Jars: If you choose to can the jam for long-term storage, you’ll need sterilized 2 half-pint jars. When canning, follow proper canning procedures and guidelines for safety.
Recipe Tips
- If you prefer a smoother consistency, you can strain out the skin and seeds before adding the jam to the jars. Don’t do this before cooking though, since they contain the natural pectin needed to help the jam set.
What does tomato jam taste like?
Tomatoes probably aren’t the first thing that come to mind when you think about jam, but they work beautifully. It’s sticky and sweet, with a super concentrated tomato flavor. And no, it doesn’t taste a thing like ketchup. It has all of the bright summer tomato flavor that tomatoes you can buy in the winter lack.
How to use tomato jam
Once you taste it, you’ll find a million ways to use this savory jam. I love it on crackers (with or without a little creamy goat cheese or cream cheese), spread on a grilled cheese sandwich (try it mozzarella and pesto for a wintertime caprese), or on burgers. You can also combine it with balsamic vinegar to make a lovely marinade for steak or mix it with cumin for a fantastic chutney-like accompaniment to chicken breast or fish.
What are the best tomatoes for jam?
Plum tomatoes are perfect for jam because they’re nice and meaty, with a bright tomato flavor. You can use any tomatoes you happen to have though. Green tomatoes are also fantastic! Just be sure to use the ripest summer tomatoes that you can get your hands on for the best flavor.
How long does tomato jam keep in the fridge?
Sealed tightly, this tomato jam will keep well in the refrigerator for about 2 weeks or in the freezer for about 6 months. You can also can the jam for longer storage. If you’re interested in tomato jam canning, you can seal the jars in a hot water bath. If your choose to can your jam, be sure to use bottled lemon juice rather than fresh, since it’s has a more consistent pH level.
Can I double or triple the recipe?
Yes, but it will take much longer to reduce to the right consistency.

Summer Tomato Jam
Ingredients
- 2 pounds ripe tomatoes cores removed
- 1 ½ cups light brown sugar
- ¼ cup lemon juice
- 1 Tablespoon lemon zest
- 1 teaspoon freshly grated ginger or 1/4 teaspoon ground ginger
- 2 half-pint jars sterilized (optional), for canning)
Instructions
- Add the tomatoes to a blender or food processor. Pulse several times to crush the tomatoes.
- Transfer the tomato puree to a medium skillet set over medium heat. Stir in the brown sugar, lemon zest and juice, and ginger. Cook, stirring frequently, until the mixture is thick and jammy – this will take about an hour. (To test, dip a cool metal spoon into the jam. It should slide of the spoon in a thick sheet – not in watery droplets.)
- Ladle hot jam into the jars. Store in the refrigerator or freeze.
- Alternately, wipe the rims of the sterilized jars, cover with the lids, and screw the bands on until they're just barely tight. Seal in a hot water bath for 20 minutes. Carefully remove the jars from the pot and let them rest on the counter for at least 6 hours. You should hear the jars make a "ping" sound when they seal. The homemade jam is delicious right away, but tastes even better after a few weeks.
Do you take skins off tomatoes?
nope!
My mom made tomatoes presures when I was a Child, good on Hot Bisicuts. In the 80’s I made tomatoe jelly from fresh Juice.
I don’t have a scale, and will be using garden tomatoes. I need to have the measurement for the tomatoes in cups, not pounds. Do you know the approximate cups for this recipe?
Sorry, I don’t have measurements like that for this recipe. 🙁
2 pounds is 32 ounces which equals 4 cups.
I had my grandson stand on the scales once I knew his weight I gave him a bag of tomatoes and added tomatoes to the bag until I got the pounds I needed. I wanted to triple the recipe so I needed 6 pounds. His weight 43 pounds then add the tomatoes until the scales showed 49pounds.
smart!!
If you don’t have a food processor or blender ,what would be the best way to crush the fresh tomatoes?
you can grate them into the pot over the course side of box grater. Just watch your knuckles! 🙂
Can we cook this recipe without using brown sugar. Because I don’t like brown sugar.
I haven’t tried it but you can try substituting the same amount of white sugar. The jam won’t have the same deep flavor though and might seem sweeter.
If you try it, let me know how it comes out.
Is there a certain variety of tomatoes that this recipe calls for? 🙂
Any tomatoes will work, but I usually use romas.
I also use Roma tomatoes from my garden. I think they are the best variety for caning. I also use honey as a substitute for any kind of sugar. Adding 2-3 fresh basil leaves will make this jam more fresh and tasty.
Hi! I definitely want to try making this but canning frightens me, I grew up eating all kinds of canned food but I’m afraid that I won’t get it right & will make someone sick. Can this be done as a freezer jam & if so, how long will it be good for?
I definitely understand the hesitation on canning! Unfortunately I’ve never tried freezing it, so I’m not sure (if you give it a try, let me know!). It does last for a while in the fridge, so you could just do a small batch and keep it that way. That’s what I do when I don’t feel like going through the hassle of canning it.
I am definitely trying this…I love tomato jam! Sometimes I pick it but I’d rather just make my own!
Mmmm beautiful! I bet this would taste even extra special with home grown tomatoes.
Hi! My husband LOVES tomato jam & he said this was theeee best!!! I actually centered my brothers Christmas present around it! He got a jar of jam, The Little House Cookbook & a DVDs series of Little House on the Prairie, he LOVED it. I do have a question: what’s the shelf life? (Our didn’t last long enough to know!) Thank you.
