Storage Tips

How to Keep Tomatoes Fresh for Longer

Don't let good tomatoes go bad.

Tomatoes

If you want to get a room full of food lovers fired up, announce to everyone that you refrigerate your tomatoes and watch the vitriol flow. After all, refrigerating tomatoes is an absolute no-no—right?

As Harold McGee, our go-to guy for all food science questions, laid out in his book On Food and Cooking: “Tomatoes came originally from a warm climate, and should be stored at room temperature.” He notes that anything other than fully ripe tomatoes really suffer after refrigeration in every way—flavor development, coloration, and mealy texture.

However, the key phrase to pay attention to here is “anything other than fully ripe tomatoes.” Temperatures below 55° F (like the inside of your refrigerator) halt tomatoes’ flavor-producing enzyme activity. McGee notes that while fully ripe tomatoes are still susceptible to flavor loss when placed in the refrigerator, some of that enzyme activity can come back if they are allowed to recover for a day or two at room temperature before eating.

Serious Eats did extensive tomato storage research and taste testing and found essentially the same thing: “Because peak-season market tomatoes are already perfectly ripe, they benefit very little from extra time in the heat, and in many cases they are harmed by it, while the refrigerator does minimal harm once tomatoes are ripe.” They kept tomatoes in the fridge for up to 4 days no problem.

Takeaway: If you have a cool spot in your home, like a wine cellar or root cellar, with temperatures in the 55° F to 70° F range, store fully ripe tomatoes there. They’ll keep well for a day or two, and you won’t risk disrupting any flavor-producing enzyme activity. If, like us, you don’t have a wide variety of temperature zones in your home, rest assured that fully ripe tomatoes will survive refrigeration, just plan for some room temperature recovery time.

But what about tomatoes that aren’t quite ripe? You definitely shouldn’t put those tomatoes in the refrigerator. They need to stay at room temperature, ideally in a single layer out of direct sunlight. And most importantly for keeping them fresher longer, store them stem side down while they finish ripening. America’s Test Kitchen purports that the benefits are twofold: blocking where the tomato’s stem was prevents moisture from leaving the tomato and blocks air (and thus mold and bacteria) from entering the tomato.

You might have heard not to store tomatoes upside-down because the “shoulders” (the area around the stem scar) are delicate and susceptible to bruising. If you’re worried about that, America’s Test Kitchen has a solution: Place a piece of tape over the stem scar. They found it worked as well as storing tomatoes upside down. 

So, it's okay not to gobble up all your tomatoes immediately. Not that we're stopping you.

There is Chinese Food which my favorite called tomato soup with eggs, it is so delicious.<br />Tony ~ happyinvitation.com~

Yes, this is true! I read first about it on Serious Eats and consider it one of the most useful bits of advice I've gleaned on the internet in recent memory - not to mention that there's something quite refreshing about a cold, dead-ripe tomato on a hot summer day. A flavorful ripe heirloom tomato doesn't really need to come back up to room temperature. I'm grateful that others who don't regularly follow Serious Eats have the benefit of this helpful information. ;o)

i can keep tomatoes on the counter for a while; their downfall is fruit flies that appear out of nowhere and wreak havoc on anything with soft skin (tomatoes, peaches, cherries..etc)

Try getting one of those picnic bowls that have a domed screen lid. It helped keep the fruit flies off our tomatoes that were in the kitchen. The real problem is that once they start buzzing around your house, they will lay eggs in the soil of your house plants and make more fruit flies, which hatch very quickly. You can curb that problem by sprinkling diatomaceous earth over the soil, which is completely non-toxic and natural, or sprinkle a thin layer of aquarium pebbles over your soil to prevent egg laying. We also used the fruit fly traps, and I later learned that you can mix your own solution and put it in a little bowl. You'll have to research the quantities but the ingredients are water, apple cider vinegar, and a drop or two of dish soap .

I put mine, unwashed in Debbie Meyer Green boxes. wipe out the moisture ever couple of days. They keep about 2 weeks, as long as there is no mold, so I check them before storing. These boxes work for keeping all kinds of fruits and veggies, in the fridge or out. Just need to manage the moisture. Just had some salad tonight with lettuce I put in the box and stored about 12 days ago. 3 leaves had to be tossed, the rest was crisp, fresh and delicious. The thing is that the best laid plans often go awry. and fruits and veggies I may plan to use soon, may not get used as soon as planned. The Green Boxes give me lots of leeway because spoilage is delayed quite a bit.

I have been experimenting for the past 6 months or so storing unwashed, no vinegar/water rinsed tomatoes on the kitchen counter sitting on an up-turned recycled paper drink carrier one gets from drive-thru restaurants. Without fail, I have had tomatoes still edible; no mold, no soft on-the-verge of rotting spots by doing this at three weeks. There have been times when one or two require peeling after two weeks but for the most part, they have been sliceable for sandwiches or cut into wedges for salads. On-the vine or individual does not seem to make a difference.

Canning tomatoes right now. Problem is 20lbs of tomatoes mostly ripe but some are softer than others. I got them on Thursday and needed them to last until Monday for a whole day of canning. Put them on cookie sheets not touching (took 3 for the whole 20lbs) They lasted nicely that way. Luckily my kitchen is not too hot since San Francisco summers are not known for being warm. I've also sometimes put the whole box of tomatoes on the fire escape each night and in a cool shady place inside during the day to keep them longer. I will try an experiment of putting any tomatoes that are getting too ripe in the fridge and compare their texture and taste to the unrefrigerated ones.

Something that gets left out of the refrigerate/not refrigerate discussions is that room temperature varies greatly in kitchens. In hot Southern California or if you do a lot of baking anywhere your kitchen is warmer than someone else's kitchen. For that reason I keep onions and potatoes in the refrigerator which I am told repeatedly not to do. Unfortunately I need my onions and potatoes to last more than a day or two. Once anything is ripe it goes in the refrigerator too.

How do you storage a tomato after it’s been cut. If we don’t eat the whole tomato how do we store it.

I turn it cut side down on a plate and refrigerate it covered with wax paper. The cut side seems to be less slimy when I use it again. This works got me - I just kept experimenting with different ways of storing them and this works best.

Very Good Information to know. I have been juggling with "do I or don't I" keep fully ripened tomatoes in the frig. Now, I can tell hubby he can have his "cold" tomatoes if he wants!! Thanks again for the info.

I put my ripe tomatoes, the ones without unhealed cracks or bruises, in a box in a single layer, then set them on the floor in front of my air conditioning vent. It's just enough of a cooling effect to hold them a bit longer. If I want 4 or 5 days more, I put the box on the floor in the corner of the basement.

Good to know. I have so many in my garden right now. I can't keep up with them ripening.<br /><br />xoxoBella | http://xoxobella.com
