Look for plump, heavy tomatoes with smooth skins free of bruises, blemishes or cracks. Their leaves should look fresh and green. Fully ripe tomatoes are softer and will give a little to the touch. You only want to buy fully ripe tomatoes if you’re planning on using them right away
How Long Do They Last
There’s no precise answer to this, because it depends on how ripe they are when you buy them, how you store them and whether you refrigerate them or not. Typically they will last on the counter for up to 7 days, but keep them away from direct sunlight. Fully ripe tomatoes can be stored in the refrigerator for a day or two, but if you keep them there any longer, you will have a watered down, mealy and mostly tasteless tomato on your hands. Don’t put them unripe in the refrigerator because this will stop the ripening process.
