Ingredients:
Before you embark on your tomato jam-making journey, gather the following ingredients:
1. Ripe tomatoes (around 3 pounds)
2. Granulated sugar (2 cups)
3. Lemon juice (2 tablespoons)
4. Ground cinnamon (1/2 teaspoon)
5. Ground ginger (1/2 teaspoon)
6. Salt (1/4 teaspoon)
Equipment:
1. Cutting board
2. Chef's knife
3. Large mixing bowl
4. Heavy-bottomed pot
5. Wooden spoon
6. Immersion blender or regular blender
7. Sterilized glass jars with lids
The key to a delicious tomato jam is using ripe, flavorful tomatoes. Look for varieties like Roma,
San Marzano, or any other tomatoes with a good balance of sweetness and acidity. The fresher
the tomatoes, the better the flavor of your jam.
Wash the tomatoes thoroughly and remove the stems. Cut them into quarters, removing the
seeds and excess liquid. Deseeding the tomatoes will help create a thicker jam with a more
concentrated flavor. Transfer the quartered tomatoes to a large mixing bowl.
Add the granulated sugar, lemon juice, ground cinnamon, ground ginger, and salt to the bowl of
quartered tomatoes. Gently toss the ingredients together, ensuring the sugar and spices evenly
coat the tomatoes. Let the mixture sit for about 30 minutes to allow the tomatoes to release their
juices and absorb the flavors.
Transfer the tomato mixture to a heavy-bottomed pot and place it on the stove over medium
heat. Stir the mixture frequently with a wooden spoon to prevent sticking. As the mixture
simmers, the tomatoes will break down, and the sugar will dissolve, creating a thick and
luscious jam.
During the cooking process, add an additional splash of lemon juice. Lemon juice not only
enhances the flavor of the jam but also acts as a natural preservative. Stir the lemon juice into
the mixture and continue to simmer until the jam reaches the desired consistency. This usually
takes about 60-90 minutes.
To test the consistency of your tomato jam, place a small amount on a cold plate and let it cool
for a minute. Run your finger through the jam to check if the jam wrinkles and keeps its shape.
Continue simmering and repeat the test every 10 minutes until you achieve the desired
consistency.
For a smoother texture, use an immersion blender to puree the jam directly in the pot. If you
don't have an immersion blender, carefully transfer the hot mixture to a regular blender in small
batches, blend until smooth, and return it to the pot.
While the tomato jam is finishing its last few minutes of cooking, sterilize your glass jars and lids
by placing them in a boiling water bath for 10 minutes. This step is crucial for preserving the jam
and preventing any bacterial contamination.
Once the tomato jam has reached the desired consistency, carefully ladle it into the sterilized
jars, leaving about 1/4 inch of headspace. Wipe the rims of the jars with a clean, damp cloth to
ensure a proper seal.
Place the sterilized lids on the jars and tighten them. Process the jars in a water bath for an
additional 10-15 minutes to ensure a secure seal. Allow the jars to cool completely before
storing them in a cool, dark place.
Homemade tomato jam is a versatile and flavorful addition to your pantry, offering a burst of
summer in every spoonful. Following this step-by-step guide will not only result in a delicious
condiment but also provide you with the satisfaction of creating something truly special in your
own kitchen. Experiment with different spices and herbs to tailor the flavor to your liking, and
enjoy the fruits of your labor throughout the year. Whether spread on toast, paired with cheese,
or used as a glaze for meats, your homemade tomato jam is sure to be a hit with family and
friends!
