How to Choose the Best Sweet Corn
The best corn on the cob is fresh with plump, sweet kernels. I like to buy my corn on the cob at the farmer’s market whenever possible because I know it will be the freshest. To pick the best ears of corn, follow these steps:
- Look for bright green husks. The husks should be wrapped tightly around the cob. Fresh husks may be slightly damp. Avoid buying corn with husks that are dry or yellowish.
- Check the tassel. The tassel is the silks that are sticking out of the top of the corn. The tassel should be brown or golden in color. The tassel should be silky, slightly sticky and moist. Avoid buying corn if the tassel is black or dry.
- Look for a fresh stalk. If the bottom of the corn where it was broken off of the stalk is brown, the corn is likely a few days old.
- Check for insect holes. If you see tiny brown holes in the husk, it is a sign that there might be worms or other bugs in the corn.
- Feel for plump kernels. You should be able to feel firm, plump kernels through the husk. If you feel soft spots or empty spots where kernels are missing, don’t choose that ear of corn.
You don’t need to peek! It’s common practice to peel back the husks at the top of corn to check the tip of the corn cob. Opening up the husk in this way shortens the shelf life of your corn. You can choose delicious sweet corn by following the steps above, no peeking required.
How to Cook Corn on the Cob in an Instant Pot
There are just a few simple steps to cooking sweet corn in your Instant Pot. You’ll start by removing the husks and silks.
Then pour 1 cup of cold water into your Instant Pot inner pot. Use 1 cup of water in a 6 quart Instant Pot, and 1 1/2 cups of water if you are using an 8 quart pot.
Put the metal trivet in the bottom of the pot. You’ll set the corn on the trivet so that it isn’t sitting in the water or touching the bottom of the pot.
When you place the ears of corn on top of the trivet, arrange the different layers of corn in alternating directions. You can see how I did this in the photo. This helps the air to circulate around the ears of corn so that it cooks evenly. You should be able to fit 3 ears of corn in each layer.
After closing the Instant Pot lid and turning the steam release valve to the sealing position, set the pressure cook time to 2 minutes at high pressure. The Instant Pot will take about 12-15 minutes to reach pressure and then the cook time will start counting down.
As soon as the cook time ends, quick release the pressure by using the handle of a long spoon to turn the steam release valve to the venting position. When the steam finishes escaping and the pin drops down, open the lid. Your corn is done and ready to enjoy!
Tips for cooking Instant Pot corn on the cob:
- You can fit up to 6 ears of corn in a 6 quart Instant Pot and up to 9 ears of corn in an 8 quart Instant Pot.
- Remember to arrange the layers of corn in opposite directions in your Instant Pot, as shown in the photo.
- Trim the stalks if the cobs are too long to fit in the pot.
- Quick release the pressure as soon as the cook time ends to keep the corn from over-cooking.
- Serve your corn with butter, salt and pepper, or as desired.
Can you cook corn in the husks?
I wondered if it would be easier to remove the husks and silks after cooking the corn, so I tried cooking corn in the husks in my Instant Pot. What I found was that it wasn’t any easier to shuck the corn after it was cooked. The corn was too hot to handle when it first came out of the pot, so I had to wait for the corn to cool. When the corn was cool enough to shuck after cooking, I was in a rush finishing up the rest of our meal and trying to get dinner on the table.
It’s much easier to get dinner on the table when you remove the husks and silks before cooking the corn, and you can prep your corn ahead earlier in the day to save time later. If you really want to cook corn in the husks, you should add one minute to the pressure cook time.
How to Store Corn on the Cob
- Before Cooking: Store fresh ears of corn at room temperature if you plan to cook them within a few hours. For longer storage, keep the husks on, wrap the corn tightly in a plastic bag, and store in your refrigerator. Fresh corn on the cob is best cooked within 1-2 days, but may last in the refrigerator for 3 days.
- After Cooking: Let the corn cool, and be sure to refrigerate within two hours of cooking. Place corn in a zip-top bag and seal, or store in an airtight container. The corn will last in the refrigerator for about 3 days. You can also freeze cooked corn by cutting the kernels off of the cob and freezing in an airtight container for up to 3 months.
