How to Keep Tomatoes Fresh for 6 Months: Grandma's Tried and True Method Using Glass Containers

Sterilizing Glass Containers: Importance of Sterilization: Sterilization is a crucial step in this method of preservation. Using unsterilized containers can introduce bacteria and other microorganisms that can spoil the tomatoes.
Sterilization Process: To sterilize, wash the glass containers and lids with hot, soapy water. Then boil them in a large pot for about 10 minutes. Carefully remove the containers and lids and let them dry completely.

Storing Tomatoes: Layering Technique: Start by placing a layer of tomatoes in the container. Make sure they are not too tightly packed; there should be a little space between each tomato to prevent bruising and allow air circulation.

Sealing and Storing: Once the container is full, seal it tightly with the lid. Store the containers in a cool, dark place, such as a cellar or pantry. Avoid areas with large temperature fluctuations.

Tips for Long-Term Freshness: Regular Checks: It is essential to check the tomatoes regularly. If you notice any spoiled tomatoes, remove them immediately to prevent the damage from spreading to others.

Ideal Storage Conditions: Maintain a constant, cool temperature. Extremes of both cold and hot temperatures can harm tomatoes.

The science behind the method: This method works because sealed glass containers create a barrier against oxygen, moisture, and light—three factors that contribute to tomato spoilage. By limiting these factors, it’s possible to significantly extend the shelf life of tomatoes.
