How To Store Plum Tomatoes

Proper storage helps maintain the freshness and flavor of plum tomatoes. Here are some tips on how to store them:

1. Room Temperature (Short Term):
   • If your plum tomatoes are not fully ripe, you can store them at room temperature. Keep them in a single layer on the kitchen counter, away from direct sunlight. However, keep in mind that storing them at room temperature may cause them to ripen more quickly.
2. Refrigeration (Longer Term):
   • For longer storage, especially if the tomatoes are already ripe, it’s advisable to refrigerate them. Place the tomatoes in the vegetable crisper drawer of the refrigerator. Ripe plum tomatoes can be stored for up to a week in the fridge.
3. Keep Them Dry:
   • Moisture can lead to mold and spoilage. Make sure the tomatoes are dry before storing them. If they are damp, you can gently pat them dry with a paper towel.
4. Avoid Plastic Bags:
   • Store plum tomatoes loosely and avoid sealing them in plastic bags. Plastic can trap moisture and accelerate spoilage. Instead, use a perforated plastic bag or place the tomatoes in a paper bag to allow for air circulation.
5. Separate Overripe Tomatoes:
   • If you have a mix of ripe and unripe tomatoes, store them separately. Overripe tomatoes can release ethylene gas, which speeds up the ripening process of nearby fruits and vegetables.
6. Check Regularly:
   • Periodically check your stored tomatoes for ripeness and any signs of spoilage. Use ripe tomatoes promptly to prevent them from becoming overripe and mushy.
7. Avoid Refrigerating Unripe Tomatoes:
   • If your plum tomatoes are not yet ripe, it’s best to keep them at room temperature until they reach the desired level of ripeness. Refrigerating unripe tomatoes can affect their flavor and texture.
8. Store Cut Tomatoes Properly:
   • If you have cut or sliced plum tomatoes, store them in an airtight container in the refrigerator. Use them within a few days for the best quality.

Remember that tomatoes are sensitive to cold temperatures, and refrigeration can affect their texture. If you refrigerate them, allow them to come to room temperature before consuming for better flavor. Additionally, use the oldest tomatoes first to minimize waste and ensure freshness.
