Dulce de Tomate: A Taste of Argentina in a Jar

The first time I tasted dulce de tomate was on a trip to Buenos Aires. My abuela, sensing my curiosity about Argentinian cuisine, ushered me into her sun-drenched kitchen. A comforting aroma of simmering sweetness filled the air. She presented me with a slice of toasted bread, slathered with a deep-red, glistening jam. It was unlike anything I had ever tasted; a burst of concentrated tomato flavor, transformed by sugar and time into a decadent spread. Each bite was a sweet memory of her kitchen and a reminder of the simple, profound magic of turning ordinary ingredients into something extraordinary. I have been perfecting my own recipe ever since, and now I am happy to share my version with you.

Recipe Overview

Prep Time: 45 minutes
Cook Time: 2-3 hours
Total Time: 3-4 hours
Servings: Varies
Yield: Approximately 8 cups
Dietary Type: Vegan, Gluten-Free

Ingredients

4 1/2 kg Tomatoes (about 4-5 kg whole, to yield 3kg peeled and seeded)
1 1/2 kg Jam Sugar
500 ml Water

Equipment Needed

Large pot
Bowl
Weighing scales
Large saucepan or preserving pan
Wooden spoon
Thermometer (optional, for jam making)
Sterilized jars with lids
Jam funnel (optional but recommended)
Cake rack or old tea towel
Large pot for water bath canning

Instructions

Begin by washing the tomatoes. Bring a large pot of water to a rolling boil.
Once the water is boiling, carefully submerge the tomatoes in the boiling water for just a few seconds. This process, known as blanching, helps loosen the skins.
Immediately transfer the blanched tomatoes to a bowl of ice water to stop them from cooking further. This “shocking” process also makes the skins easier to peel.
Peel the tomatoes – the skins should slip off easily. Cut each tomato in half and remove the seeds. This step is crucial for achieving the right texture in your dulce de tomate.
Weigh the peeled and seeded tomatoes. The recipe calls for 3 kg of tomato flesh after processing. If you have slightly more or less, adjust the sugar and water proportionally, maintaining the ratio of 1.5 kg sugar and 500 ml water for every 3 kg of tomato flesh.
In a large saucepan or preserving pan, combine the water and sugar. Place the pan over medium heat.
Stir constantly until the sugar has completely dissolved in the water, creating a clear syrup. This step is vital to prevent the sugar from crystallizing later.
Increase the heat and bring the syrup to a boil.
Gently add the prepared tomatoes to the boiling syrup.
Reduce the heat to a simmer and cook for 15-20 minutes, stirring occasionally. Keep a close watch on the pot, as the mixture can become foamy and potentially boil over. Skim off any foam that forms on the surface.
After 20 minutes, turn off the heat and let the mixture sit and macerate for a few hours, allowing the flavors to meld. This resting period intensifies the final taste of the dulce de tomate.
After the resting period, return the pan to the stove. Re-heat the mixture over low heat, stirring continuously with a wooden spoon to prevent sticking and burning.
Bring the mixture back to a boil, then immediately reduce the heat to a low simmer. Cook for 1-2 hours, stirring periodically. The cooking time will vary depending on the tomatoes and the desired consistency of the jam.
During the cooking process, monitor the consistency of the syrup. You are aiming for a jelly-like set. An optional way to check doneness is to use a thermometer; the temperature should stabilize at 104°C (219°F). Alternatively, place a small spoonful of the jam on a chilled plate. If it sets quickly and wrinkles when pushed with your finger, it is ready.
After the appropriate cooking time, the tomatoes should appear shiny and somewhat translucent.
While the jam is cooking, prepare your jam jars. Wash the jars thoroughly and drain them well. Place the jars in a preheated oven at 100°C (212°F) for 15 minutes to sterilize them. Place the lids in a separate pan and boil them for 10 minutes to sterilize the rubber seals.
Carefully remove the hot jars from the oven. Using a jam funnel (if you have one), pour the hot dulce de tomate into the hot jars, leaving about 1/4 inch of headspace at the top.
Immediately seal the jars with the sterilized lids.
Place a cake rack or an old tea towel at the bottom of a large pot. This prevents the jars from sitting directly on the bottom, which can cause them to crack during the canning process.
Carefully place the sealed jars in the pot, ensuring they don’t touch each other. Pour hot water over the jars until they are fully submerged by at least an inch.
Bring the water to a simmer and simmer for 10 minutes. This water bath canning process creates a vacuum seal, ensuring the long-term preservation of your dulce de tomate.
Carefully remove the jars from the water bath and allow them to cool completely on a towel-lined surface. As the jars cool, you should hear a “pop” sound, indicating that the lids have properly sealed.
Once the jars are completely cool, check the seals by pressing down on the center of each lid. If the lid doesn’t flex or pop back up, the jar is properly sealed. If a lid isn’t sealed, you can either reprocess the jar with a new lid or store the jam in the refrigerator for immediate use.

Expert Tips & Tricks

Use high-quality tomatoes: The flavor of your dulce de tomate will be directly influenced by the quality of the tomatoes you use. Opt for ripe, flavorful varieties.
Don’t rush the cooking process: Allowing the jam to simmer slowly over low heat is essential for developing the rich, concentrated flavor.
Skim off the foam: Removing any foam that forms on the surface of the jam during cooking will result in a clearer, more visually appealing final product.
Consider adding lemon juice: A tablespoon or two of lemon juice can help balance the sweetness of the tomatoes and also acts as a natural preservative.
Experiment with spices: For a more complex flavor, try adding a pinch of cinnamon, cloves, or a star anise to the jam during cooking. Remove the star anise before jarring.

Serving & Storage Suggestions

Dulce de tomate is incredibly versatile. Serve it as a spread for toast or crackers, as an accompaniment to cheese, or as a glaze for grilled meats. It is also delicious served with scones and clotted cream, or used as a filling for tarts and pastries.

Properly sealed jars of dulce de tomate can be stored at room temperature for up to a year. Once opened, refrigerate the jam and consume it within a few weeks.

Variations & Substitutions

Spicy Dulce de Tomate: Add a finely chopped chili pepper (such as jalapeño or habanero) to the jam during cooking for a spicy kick.
Herb-Infused Dulce de Tomate: Incorporate fresh herbs like rosemary, thyme, or basil for a savory twist. Add the herbs during the last 30 minutes of cooking and remove before jarring.
Low-Sugar Dulce de Tomate: Use a sugar substitute suitable for jam making to reduce the sugar content. Be aware that this may affect the set of the jam, so you may need to add pectin.
Smoked Paprika Dulce de Tomate: Add a teaspoon of smoked paprika during cooking for a smoky depth of flavor.

FAQs (Frequently Asked Questions)

Q: Can I use frozen tomatoes for this recipe?
A: While fresh tomatoes are ideal, you can use frozen tomatoes. Thaw them completely and drain off any excess liquid before using.

Q: Do I have to sterilize the jars?
A: Yes, sterilizing the jars is essential for preventing spoilage and ensuring the long-term preservation of your jam.

Q: Can I use a different type of sugar?
A: Jam sugar is specifically formulated to help jam set properly. While you can use regular granulated sugar, you may need to add pectin to achieve the desired consistency.

Q: How do I know if the jars are properly sealed?
A: After the jars have cooled, press down on the center of each lid. If the lid doesn’t flex or pop back up, the jar is properly sealed.
