How to Preserve Tomatoes for Two Years Without Vinegar or Preservatives
Tomatoes are one of the most commonly used ingredients in the kitchen, whether for daily cooking or preparing sauces and appetizers. However, during their peak season, tomatoes are abundant and inexpensive. Over time, their quality declines, and prices rise. As a result, many people look for effective methods to preserve tomatoes for long periods without losing their flavor or nutritional value.
Today, we present a traditional, tried-and-true method to preserve fresh tomatoes for up to two full years without using any vinegar, preservatives, or even salt. This method is simple but requires precision in sterilization and storage.
Why This Method Works?
- No Preservatives: No vinegar, no salt—just pure tomatoes.
- Preserves Flavor: The tomatoes retain their natural flavor without alteration.
- Healthy & Safe: It relies solely on proper sterilization and correct storage.
- Cost-Effective: Save money by buying in bulk during peak season and preserving them for the entire year.
Ingredients and Tools:
Ingredients:
- Fresh, ripe, firm tomatoes without blemishes or soft spots.
Tools:
- Glass jars with tight-fitting lids (preferably pre-sterilized)
- A large pot for water bath sterilization
- Clean cotton towels
- Kitchen tongs
- A large towel to line the bottom of the pot (to prevent jars from clashing)
Detailed Steps for Preparation:
1. Choose the Right Tomatoes
Start by selecting medium to small-sized tomatoes that are ripe but not overly soft. Avoid tomatoes with dark spots, cracks, or excessive ripeness.
2. Wash and Dry the Tomatoes
Wash the tomatoes thoroughly under running water to remove any dirt or debris. Dry them completely with a clean cloth. It’s best to let them air-dry a little to ensure no moisture remains.
3. Sterilize the Jars
Place the jars and lids in a pot of boiling water for 10 minutes.
Alternatively, you can sterilize them by placing them in a preheated oven at 120°C (250°F) for 15 minutes.
After sterilizing, place the jars on a clean towel and avoid touching the insides.
4. Fill the Jars with Tomatoes
Carefully place whole tomatoes inside the jars one by one. Press gently to minimize air gaps without squashing the tomatoes.
Continue filling the jars, leaving about 1 cm (½ inch) of space at the top.
Note: Do not add any water, vinegar, or salt.
5. Seal the Jars Tightly
Clean the rim of the jar with a clean, dry cloth.
Tighten the lid firmly, but don’t over-tighten it.
6. Water Bath Sterilization (The Crucial Step)
In a large pot, place a towel at the bottom to protect the jars.
Arrange the jars inside the pot, ensuring they don’t touch each other.
Pour hot water over the jars until they are fully submerged.
Place the pot on medium to high heat until the water starts boiling.
Once the water is boiling, reduce the heat slightly and continue boiling for 40 to 60 minutes (depending on the size of the jars).
7. Cooling and Creating a Vacuum Seal
After the boiling time, carefully remove the jars using kitchen tongs.
Turn the jars upside down and leave them to cool completely in this position.
Once cooled, you should hear a “pop” sound, which indicates that the vacuum seal has been successfully created.
Storage:
Store the jars in a dark, cool, and dry place, such as a pantry or closed cabinet.
Make sure they are not exposed to sunlight or humidity.
Shelf Life:
When done correctly, the tomatoes will remain good for up to two years without any issues. Just ensure that the lid hasn’t deformed or released air when opened.
How to Use the Preserved Tomatoes:
When you’re ready to use them, simply blanch the tomatoes for a few minutes, peel them, and incorporate them into sauces, soups, or cooking.
The flavor will be very close to fresh tomatoes, and sometimes even better since they are preserved in their natural juice.
Important Tips for Success:
- Don’t use any tomatoes that have blemishes or signs of spoilage.
- Do not open the jars until you’re ready to use them.
- If you notice any bubbles or unusual smells after opening, discard the contents.
- Make sure to sterilize everything properly at every step.
By following this simple and traditional method, you’ll be able to make the most of the tomato season and save time and money throughout the year. No need for preservatives or additives—nature does the work to preserve the taste and quality.
