**Introduction:**
Tomatoes, beloved for their vibrant color and versatile flavor, are a staple ingredient in many cuisines around the world. While they are abundant during the summer months, preserving them for enjoyment throughout the year, especially in the winter, requires proper techniques. In this guide, we delve into a method that allows you to store tomatoes for up to two years without the need for water, salt, or vinegar.
**Preparing the Tomatoes:**
Begin by selecting ripe, firm tomatoes. Washing them under running water, ensure they are thoroughly rinsed and remove any stems. Once cleaned and dried, arrange the tomatoes on a baking tray suitable for the oven. Preheat the oven to 200 degrees Celsius (approximately 390 degrees Fahrenheit).
**Oven Roasting:**
The key to this preservation technique lies in pre-cooking the tomatoes. Place the tray of tomatoes in the preheated oven and roast them for about 20 minutes. This initial roasting process helps concentrate their flavors and kick-starts the preservation process.
**Preparing the Storage Jars:**
While the tomatoes are roasting, prepare clean and dry glass jars with a capacity of at least one and a half liters, equipped with tight-fitting lids. Ensure the jars are sanitized to maintain the integrity of the preserved tomatoes.
**Filling and Sterilizing the Jars:**
Once the tomatoes are out of the oven, carefully transfer them into the prepared jars using a spoon. Take caution to fill the jars slowly to avoid any splattering. Meanwhile, bring water to a boil in a pot, filling it to about one-third of its capacity. Place a clean cloth at the bottom of the pot to prevent the jars from breaking.
Next, immerse the filled jars into the pot, ensuring they are submerged halfway in the boiling water. Loosely cover the jars with their lids, allowing some airflow. Cover the pot and let it sterilize for 20 minutes.
**Sealing and Storing:**
After the sterilization period, turn off the heat and carefully remove the jars from the pot using a cloth. Wipe them clean on the outside and seal the lids tightly with a specialized utensil. It’s crucial to prevent any air from entering the jars during this process.
**Conclusion:**
By following this method, you can extend the shelf life of your tomatoes for up to two years without the need for additional ingredients like water, salt, or vinegar. With proper storage in a cool, dark place, your preserved tomatoes will be ready to enhance your culinary creations even during the off-season. Enjoy the taste of summer all year round with this simple yet effective preservation technique.
