Store the Remaining Tomato Halves, Cut Down, in the Refrigerator.
Whole tomatoes can be stored in the refrigerator or at room temperature, depending on how ripe they are . But if you’ve already cut one piece, the refrigerator is the best place for it. Here’s how to do it right and maximize freshness.
You start slicing a large, juicy tomato when you realize you only need a few slices. If you cut it all up now, they may be gone, so it’s best to save them and put them off for later. It’s best to store the leftover tomato halves, cut side down, on a paper towel, according to The Kitchn’s Megan Splawn. Glue a paper towel to the bottom of the storage container, place the open end of the tomato on the paper towel, and insert the closed container into the refrigerator. If used within two days, it tastes like new. Just make sure you take it out of the refrigerator about 30 minutes before you eat it so that it can return to room temperature and reach its perfect texture. If you can’t use it for the next few days, put it in the freezer until you need it.
