How to Preserve Fresh Tomatoes for 6 Months: Grandma’s Proven

Select and prepare the tomatoes: Choose firm, ripe tomatoes, without bruises. Wash them well and dry them completely to avoid mold.
Sterilize glass containers: Wash the jars and lids with hot soapy water. Boil them for 10 minutes and let them dry completely.
Store the tomatoes: Layer the tomatoes in the sterilized jars. Make sure not to overtighten them to avoid damage and allow air circulation.
Sealing and storage: Close the jars tightly. Store them in a cool, dark place, such as a pantry, to prolong their freshness.
Additional tips: Check stored tomatoes regularly and remove any spoiled tomatoes to prevent them from affecting the others. Maintain a constant temperature and avoid extreme fluctuations.
This traditional method ensures that you can enjoy fresh tomatoes for up to six months, thanks to the barrier that glass jars provide against oxygen and moisture.
