That’s why my neighbor envies me: I have been storing tomatoes like this for 10 years and they are always as fresh as in summer

What You’ll Need
Before starting, gather these materials:

Fresh, ripe tomatoes (preferably firm and unbruised)
Wide-mouth glass jars with airtight lids
Food-grade mineral oil or natural vegetable oil
Clean cloth or paper towels
Optional: sea salt or vinegar (for extra preservation)
