What’s Corn On The Cob?

Corn on the cob is a classic summer treat.

The ears of corn are cut from the stalk and boiled (or grilled.

) before serving, often with butter and salt added to enhance the flavor.

Considered by many to be a sweet-ish vegetable, corn on the cob offers a variety of nutrition benefits as well as being low in fat and cholesterol.

How to Store Corn On the Cob?

If you’re like most people, you probably grew up eating corn on the cob that was boiled in water.

But did you know that there’s actually a better way to store corn on the cob? It turns out that storing corn in the fridge is the best way to keep it fresh and prevent it from going bad.

When you boil corn on the cob, the water breaks down the sugars in the corn and makes them less sweet.

Storing corn in the fridge prevents this from happening and allows the corn to retain its sweetness.

To store corn in the fridge, first remove it from the husk and silks.

Then, place the ears of corn in a plastic bag and seal it shut.

Be sure to label the bag with the date so you know when you need to use it by.

Corn on the cob can be stored in the fridge for up to two weeks.

When you’re ready to eat your corn, simply remove it from the bag and cook it however you like.

You can boil it, grill it, or even eat it raw if you’re feeling adventurous.

Just be sure to enjoy it while it’s fresh.

How Long Does Corn On The Cob Last?

Corn on the cob is a summertime staple, but how long does it last? And does it go bad?

Well, fortunately, corn on the cob lasts quite awhile.

When stored properly, in a cool, dry place, it can last up to two weeks.

But of course, the fresher the corn, the better it will taste.

So if you can eat it within a few days of buying or picking it, that’s ideal.

As for whether or not corn on the cob goes bad, the answer is technically yes, but it takes quite awhile.

If stored properly, as mentioned above, it can last up to two weeks without going bad.

But if left out in warm temperatures or exposed to too much moisture, it will start to spoil and should be thrown out.

So there you have it. It lasts awhile and doesn’t go bad quickly, as long as it’s stored properly.

Enjoy this summertime treat while you can.

Can You Freeze Corn On The Cob?

You can freeze corn on the cob, but it’s not going to taste as fresh as if you had just picked it from the stalk.

The best way to preserve the flavor is to blanch the ears of corn before freezing them.

Blanching is a process of boiling the corn for a few minutes, then shocking it in ice water.

This stops the cooking process and helps preserve the flavor.

To blanch and freeze corn on the cob, start by bringing a large pot of water to a boil.

Add the ears of corn and let them cook for 3-5 minutes.

Remove them from the pot with a slotted spoon and place them in a bowl of ice water.

Once they’re cooled, dry them off and place them in freezer bags.

Squeeze out as much air as possible and seal the bags.

Label them with the date and store in the freezer for up to 6 months.

When you’re ready to eat, thaw the corn in the refrigerator overnight.

You can then cook it however you like – grilled, boiled, roasted, etc.


How to Tell If Corn On The Cob is Bad?

If you’re not sure how long your corn on the cob has been sitting in the fridge, there are a few ways to tell if it’s gone bad.

First, take a look at the kernels. If they’re starting to shrink and wrinkle, that’s a sign that the corn is past its prime.

The kernels should also be plump and firm, not soft or mushy. Another way to tell if corn on the cob is bad is by smell.

If it smells sour or musty, it’s time to toss it out.

If you’re still not sure whether or not your corn on the cob is safe to eat, the best way to tell is by cooking it.

Cut off a small piece of the cob and cook it in boiling water for a few minutes.

If the kernels are tough or chewy, that’s a sign that the corn is bad and you should throw it out.

But if the kernels are nice and tender, then you’re good to go.

So there you have it – a few easy ways to tell if your corn on the cob has gone bad.

When in doubt, it’s always better to err on the side of caution and throw it out.

That way you can enjoy fresh, delicious corn on the cob all summer long.
