Simple and Effective Ways to Preserve Tomatoes All Year Round

Tomatoes are a familiar and essential ingredient in many households. They are widely used in daily meals thanks to their rich flavor, nutritional value, and versatility in cooking. However, when tomatoes are in season, many families often harvest or buy them in large quantities and struggle to find effective ways to store them for long-term use. If you are facing the same issue, the practical tips below will help you preserve tomatoes while maintaining their taste and quality.

Preserving Tomatoes in the Freezer

Freezing is one of the easiest and most convenient ways to store tomatoes for extended periods. However, to ensure they remain flavorful and to save freezer space, proper preparation is essential.

First, wash the tomatoes thoroughly. Make a small cross-shaped cut on the top of each tomato (opposite the stem), then briefly blanch them in boiling water. This method helps remove the skin quickly without damaging the flesh.

Next, cut the tomatoes lengthwise, remove the seeds, and chop them into smaller pieces. Blend the tomatoes until smooth, adding a small pinch of salt to enhance flavor and aid preservation.

Pour the blended tomatoes into a pot and bring to a boil. Reduce the heat and let the mixture simmer gently, stirring occasionally to prevent burning. Once the mixture thickens into a rich, concentrated texture, turn off the heat and allow it to cool.

Transfer the cooled tomato puree into large ice cube trays and freeze for 10–12 hours. Once frozen, remove the tomato cubes and store them in airtight freezer bags. These tomato cubes can be stored for up to 3–4 months. However, for the best flavor and nutritional value, it is recommended to use them within the first 2 months.

Alternatively, if your freezer has enough space, you can freeze whole tomatoes. Choose firm, undamaged tomatoes, wash and dry them thoroughly, then place them in freezer bags. When needed, simply rinse the frozen tomatoes under running water—the skin will peel off effortlessly, making them easy to use in cooking.

Preserving Tomatoes by Drying

Drying tomatoes is another excellent way to extend their shelf life while creating a flavorful ingredient for salads, pasta, and snacks.

Ingredients and Tools

• 2 kg fresh tomatoes

• A small amount of salt

Step 1: Prepare the Tomatoes

Wash the tomatoes, remove the stems, and cut them into wedges (4–6 pieces each). You can also slice them into rounds, depending on your preference.

Step 2: Season the Tomatoes

Place the tomatoes in a bowl, sprinkle with salt, and gently mix. Let them rest for about 10 minutes to allow the seasoning to absorb. If the tomatoes are very sour, you may add a small amount of sugar to balance the taste.

Step 3: Dry the Tomatoes

There are several drying methods you can choose from:

• Sun drying: Arrange the tomatoes on a tray or bamboo mat and dry them under direct sunlight for 5–6 days until completely dry.

• Oven drying: Place the tomatoes on a baking tray and dry them in the oven at 120°C (250°F) for approximately 5 hours.

• Other options: You can also use a food dehydrator or an air fryer for more consistent results.

Once dried, let the tomatoes cool completely before storing them in airtight plastic bags or glass jars. Keep them in a cool, dry place for long-term use.

Preserving Tomatoes with Salt

Another traditional method is salting tomatoes. After washing and drying them, layer the tomatoes in a clean glass jar. For each layer of tomatoes, add a layer of salt evenly on top. Continue until the jar is full.

Seal the jar tightly and store it in a cool, dry place. Using this method, tomatoes can be preserved for up to one month and are suitable for cooking dishes that require a savory flavor.

Preserving Tomatoes in Ash

This traditional preservation method is surprisingly effective. Place the tomatoes in a cardboard box or suitable container, then cover them completely with clean, dry ash. Seal the container and store it in a cool, well-ventilated area.

With this method, tomatoes can be preserved for 5–6 months while remaining firm and usable.

Preserving Tomatoes by Making Tomato Sauce

Turning tomatoes into sauce is one of the most practical ways to store them for long-term use.

First, wash the tomatoes thoroughly and boil them until soft. Remove the tomatoes, let them cool, then peel off the skin, remove the seeds, and crush the flesh.

Add a small amount of salt to the tomato pulp and cook it over low heat until it thickens slightly. Allow the sauce to cool, then transfer it into clean, dry bottles or jars.

Heat a small amount of cooking oil, let it cool, and pour a thin layer over the surface of the sauce before sealing the jar. This oil layer helps prevent air exposure and spoilage. Store the jars in the refrigerator and use gradually as needed.

By applying these simple preservation methods, you can enjoy tomatoes all year round while minimizing waste and maintaining their natural flavor and nutritional value.
