What Exactly is Tomato Jam?
Tomato jam, at its core, is a cooked preserve crafted from tomatoes, sugar, vinegar, and a medley of carefully selected spices. Unlike traditional fruit jams, tomato jam boasts a distinctive flavor profile that dances between sweet, tangy, and subtly savory notes. The sweetness, often derived from granulated or brown sugar, is beautifully balanced by the acidity of vinegar, preventing the jam from becoming cloying. The spices, a symphony of flavors like onions, garlic, chili flakes, and fresh herbs, add depth and complexity, creating a condiment that’s far more than just a spread.
While its exact origins are somewhat elusive, tomato jam has gained significant popularity in recent years as a modern twist on classic canning traditions. It represents a delicious way to extend the life of seasonal tomatoes, preserving their vibrant flavor for enjoyment throughout the year. Think of it as a sophisticated ketchup, a flavorful relish, or a versatile condiment that can enhance countless dishes.

The Ingredients for Delicious Tomato Jam
Before you embark on your tomato jam-making journey, let’s gather the essential ingredients. Remember that using high-quality ingredients will significantly impact the final flavor of your jam. Here’s what you’ll need:
Approximately four pounds of ripe tomatoes
Around two cups of granulated sugar
About one cup of apple cider vinegar (five percent acidity)
One medium yellow onion, finely chopped
Four cloves of garlic, minced
One teaspoon of red pepper flakes (adjust to your heat preference)
One tablespoon of balsamic vinegar (optional, for added depth)
One teaspoon of sea salt
Fresh herbs (such as thyme or basil), optional, to taste.
Tomato Ingredient Breakdown
Now, let’s delve into the selection of each ingredient:
Tomatoes: The foundation of any good tomato jam is, of course, the tomatoes themselves. Opt for fleshy, low-moisture varieties like Roma or San Marzano. These tomatoes have fewer seeds and a higher pulp content, resulting in a thicker, more flavorful jam. Ensure your tomatoes are fully ripe but not overripe or bruised. If fresh tomatoes are unavailable, you can use high-quality canned crushed tomatoes as a substitute.
Sugar: Granulated sugar is the standard choice for most tomato jam recipes. It provides the necessary sweetness and also acts as a preservative, helping to prevent spoilage. Some recipes also incorporate brown sugar for a richer, more caramel-like flavor.
Vinegar: Vinegar is crucial for preservation, as it increases the acidity of the jam, inhibiting the growth of harmful bacteria. Always use vinegar with five percent acidity, as specified in the recipe. Apple cider vinegar is a popular choice for its mild, slightly fruity flavor, but white vinegar or balsamic vinegar can also be used depending on the desired flavor profile.
Spices and Aromatics: This is where you can truly personalize your tomato jam. Onions and garlic add a savory base note, while red pepper flakes provide a touch of heat. Fresh herbs like thyme or basil contribute a bright, aromatic quality. Feel free to experiment with different spice combinations to create your own signature flavor. Consider adding a pinch of smoked paprika for a smoky flavor, or a dash of cumin for an earthy warmth.
Sourcing the highest quality ingredients will noticeably enhance your tomato jam. Visit local farmers markets for fresh, seasonal tomatoes. Invest in good quality vinegar. Freshly minced spices can add a world of difference in flavor too.
The Canning Equipment You’ll Need
Canning requires specific equipment to ensure the safety and longevity of your preserved goods. Here’s a rundown of the essential tools:
Water Bath Canner: A large pot with a rack to hold the jars submerged in boiling water.
Canning Jars: Glass jars specifically designed for canning, with two-piece lids (lids and bands).
Jar Lifter: A tool for safely lifting hot jars in and out of the canner.
Lid Wand: A magnetic tool for lifting sterilized lids from hot water.
Bubble Popper/Headspace Tool: A tool for releasing trapped air bubbles and measuring headspace.
Large Pot: For cooking the tomato jam.
Measuring Cups and Spoons: For accurate ingredient measurements.
Knife and Cutting Board: For preparing the ingredients.
Each piece of equipment plays a vital role in the canning process. The water bath canner creates a vacuum seal by heating the jars, eliminating air and preventing spoilage. The jar lifter allows you to safely handle the hot jars without burning yourself. The headspace tool ensures the correct amount of space is left at the top of the jar, preventing the jam from overflowing during processing.
Before you begin, carefully inspect your jars for any chips or cracks. Damaged jars can break during processing, compromising the safety of your jam. Sterilize your jars and lids according to the recipe instructions.
The Tomato Jam Recipe
Now, let’s dive into the exciting part: making the tomato jam! This recipe is inspired by the Food in Jars approach, emphasizing safety, simplicity, and delicious flavor.
Prepare the Tomatoes: Wash the tomatoes thoroughly. Core them and cut them into quarters. If desired, you can peel and seed the tomatoes for a smoother jam, but this is not strictly necessary.
Combine Ingredients: In a large, heavy-bottomed pot, combine the chopped tomatoes, sugar, apple cider vinegar, chopped onion, minced garlic, red pepper flakes, balsamic vinegar (if using), and salt.
Cook the Jam: Bring the mixture to a boil over medium-high heat, stirring constantly. Once boiling, reduce the heat to low and simmer, stirring frequently to prevent sticking.
Check for Gel: The cooking time will vary depending on the water content of your tomatoes, but it typically takes approximately one to two hours. To test for gel, place a small spoonful of the jam on a chilled plate. Let it sit for a minute, then push it with your finger. If the surface wrinkles, the jam is ready.
Prepare the Jars: While the jam is cooking, sterilize your canning jars and lids according to the manufacturer’s instructions. Keep the jars hot until you’re ready to fill them.
Fill the Jars: Using a ladle or a wide-mouthed funnel, carefully fill the hot jars with the hot jam, leaving one-quarter inch of headspace.
Remove Air Bubbles: Use a bubble popper or a clean utensil to gently release any trapped air bubbles.
Wipe the Jar Rims: Wipe the rims of the jars with a clean, damp cloth to remove any spills.
Place Lids and Bands: Place the sterilized lids on the jars and secure them with the bands, tightening them finger-tight.
Process in a Water Bath Canner: Carefully lower the filled jars into the water bath canner, ensuring that they are completely submerged in boiling water. Bring the water back to a rolling boil and process for ten minutes.
Cool the Jars: Turn off the heat and let the jars sit in the canner for five minutes before removing them with a jar lifter. Place the jars on a towel-lined surface to cool completely.
Check for Seal: As the jars cool, you should hear a popping sound as the lids seal. After twenty-four hours, check the seal by pressing down on the center of each lid. If the lid flexes, it is not properly sealed and should be refrigerated and consumed within a few weeks.
Important Canning Safety Guidelines
Canning is a science, and it’s crucial to follow tested and approved recipes to ensure the safety of your preserved goods. Always adhere to the following guidelines:
Use a recipe specifically designed for canning, such as those from Food in Jars or the National Center for Home Food Preservation.
Ensure that the food you are canning has sufficient acidity to prevent the growth of harmful bacteria.
Process the jars for the recommended time in a boiling water bath canner.
Leave the correct amount of headspace in the jars.
Check the seals of the jars after processing.
If you’re new to canning, take the time to thoroughly research the process and familiarize yourself with the necessary safety precautions. It is essential to follow instructions for prepping, cleaning, sterilizing and sealing the jars.

Troubleshooting Common Concerns
Here are answers to some common questions about tomato jam and canning:
Why isn’t my jam setting? This could be due to a lack of pectin, insufficient acidity, or undercooking. Make sure you are using ripe tomatoes, adding the correct amount of vinegar, and cooking the jam until it reaches a proper gel.
What if my jars don’t seal? Unsealed jars can be reprocessed within twenty-four hours using new lids. If you don’t want to reprocess them, refrigerate the jam and consume it within a few weeks.
Can I use a different type of vinegar? Apple cider vinegar is recommended for its flavor, but you can experiment with other types of vinegar, such as white vinegar or balsamic vinegar, adjusting the amount as needed.
Can I reduce the sugar? Reducing the sugar can affect the preservation of the jam. It’s best to follow the recipe as written, or use a low-sugar canning recipe from a reputable source.
My tomato jam is too spicy, sweet, or tangy – how can I adjust it? You can adjust the amount of red pepper flakes, sugar, or vinegar to suit your taste preferences. Start with small adjustments and taste as you go.
