If you’re a fan of enjoying tomatoes year-round, even during the winter months, learning how to preserve them properly is essential. In this guide, we’ll delve into a method that allows you to preserve tomatoes for an extended period, up to two years, without the use of water, salt, or vinegar. The secret to this preservation technique lies in a simple yet effective step: pre-cooking the tomatoes in the oven for about twenty minutes. Let’s explore how you can utilize this method to keep your tomatoes fresh and flavorful for an extended period.
Step 1: Prep Your Tomatoes
Start by washing your tomatoes thoroughly under running water. Ensure they are clean and free from any dirt or debris. Remove the stems from the tomatoes after washing. Once washed, drained, and dried, arrange the tomatoes on an oven-safe tray suitable for baking and preheat your oven to 200 degrees Celsius (approximately 390 degrees Fahrenheit).
Step 2: Oven Cooking
Place the tray of tomatoes in the preheated oven and let them cook for about 20 minutes. This initial cooking step helps in breaking down enzymes and preserving the tomatoes’ freshness and flavor.
Step 3: Prepare Glass Jars
While the tomatoes are cooking, prepare clean and dry glass jars with a capacity of at least one and a half liters, equipped with airtight lids. Properly sterilize these jars to ensure hygiene and longevity of the preserved tomatoes.
Step 4: Fill the Jars
Once the tomatoes are done in the oven, carefully fill the sterilized jars with the hot tomatoes using a spoon to avoid spills. Do this slowly and gently to pack the tomatoes efficiently without damaging them.
Step 5: Sterilization
Boil water in a large 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 due to direct heat. Submerge the jars in the pot, ensuring they are half-covered with water. Place the lids on the jars without tightening them fully.
Step 6: Sterilize and Seal
Cover the pot with a lid and let the jars sterilize in boiling water for 20 minutes. After the time is up, turn off the heat and carefully remove the jars using a cloth. Wipe the jars dry on the outside and seal the lids tightly using a specialized utensil. It’s crucial to prevent any air from entering the jars to ensure long-term preservation.
By following these steps, you can preserve your tomatoes for up to two years without the need for any additional ingredients like water, salt, or vinegar. Enjoy the freshness of summer tomatoes even during the coldest months with this simple yet effective preservation method. Experiment with different tomato varieties and sizes to create a diverse collection of preserved delights for your culinary adventures.
