This tangy homemade tomato jam transforms ordinary roma tomatoes into a versatile condiment that will revolutionize your sandwiches and appetizer boards. After discovering this recipe during tomato season last year, it has become my secret weapon for elevating everyday meals with minimal effort.
I first made this tomato jam when I was overwhelmed with garden tomatoes and needed something beyond basic sauce. Now my family requests jars as gifts, and I always keep some in my refrigerator for impromptu cheese boards.
Ingredients
- Fresh roma tomatoes: these meaty tomatoes have less moisture and concentrate flavor beautifully during cooking
- Brown sugar: provides deep caramelized sweetness that balances the acidity of tomatoes
- Fresh grated ginger: adds a warm zippy note that brightens the entire mixture
- Apple cider vinegar: enhances preservation while adding pleasant tanginess
- Ground cinnamon: brings warmth and complexity to the jam
- Ground cumin: contributes earthy undertones that make this jam uniquely savory
- Red pepper flakes: delivers gentle heat that builds gradually without overwhelming
- Salt: absolutely essential for bringing all flavors into perfect harmony
Step-by-Step Instructions
- Combine Ingredients:
- Add all ingredients to a large dutch oven or heavy-bottomed pot. The heavier your pot, the less likely your jam will scorch during the long simmer. Make sure to chop tomatoes roughly but consistently for even cooking.
- Bring to Boil:
- Heat the mixture over medium-high heat until it reaches a full rolling boil. The tomatoes will start releasing their juices almost immediately, creating a soupy consistency. This step awakens all the flavors and begins the melding process.
- Simmer Gently:
- Reduce heat to maintain a gentle bubble and simmer for 2-3 hours. This lengthy cooking time allows excess moisture to evaporate while concentrating flavors and developing that perfect jammy texture. Stir frequently, especially during the final hour, to prevent burning on the bottom.
- Test Consistency:
- The jam is done when most liquid has evaporated, leaving a thick, spreadable consistency. Drag a wooden spoon through the center of the pot—the jam should be slow to fill back in, almost like thick ketchup. The color will have deepened to a rich reddish-brown.
- Cool and Store:
- Allow jam to cool completely to room temperature before transferring to storage containers. The jam will continue to thicken slightly as it cools, developing its final texture and allowing flavors to fully marry.

My absolute favorite ingredient in this recipe is the freshly grated ginger. I discovered its importance when I once substituted powdered ginger and missed that bright zingy quality. My mother-in-law now requests I bring a jar whenever we visit—she claims it makes her grilled cheese sandwiches "restaurant-worthy."
Serving Suggestions
Transform this tomato jam into an impressive appetizer by pairing it with a cheese board. It particularly shines alongside creamy brie, sharp cheddar, or tangy goat cheese. Add crackers, sliced baguette, and some nuts for a complete presentation that will impress guests with minimal effort.
For everyday meals, use this jam as a sophisticated alternative to ketchup. It adds complex flavor to burgers, grilled cheese sandwiches, or even scrambled eggs. The sweet-savory profile works beautifully with rich foods, cutting through fattiness with its balanced acidity.

Perfect Pairings
While this jam stands magnificently on its own, certain flavor companions bring out its best qualities. Try spreading it on toast with avocado and a poached egg for breakfast. For lunch, layer it with turkey and brie for an elevated sandwich. At dinner, spoon a dollop beside grilled meats as an instant sauce that brightens the plate.
The jam also makes an excellent glaze for roasted meats. Brush it on chicken thighs or pork tenderloin during the last few minutes of cooking for a glossy, flavorful finish that caramelizes beautifully in the oven.
Troubleshooting Tips
If your jam seems too watery after the recommended cooking time, continue simmering uncovered until it reaches the desired consistency. Roma tomatoes typically have less water content, but juicier varieties may require longer cooking.
For jam that's too thick or caramelized, add a splash of water or additional vinegar to loosen it up. Remember that the jam will thicken further as it cools, so aim for a slightly looser consistency than your final goal.
