How to Buy and Cook Sweet Corn on the Cob
I’m thinking of eating fresh Jersey corn every night for the next week. That’s because I’m on vacation with my family at the Jersey shore and the corn is incredible this year. As sweet as my 4 year old daughters smile, I can’t get enough of it. Although we’ve been serving it on the cob, there are dozens of ways to serve it off the cob. For example, you might see fresh corn in salads, fritters, salsas, chowders or all by itself.

What’s In A Name?
Did you know there are over 200 varieties of sweet corn?
Although you rarely seen fresh corn sold by name, I think it’s about time. With names like “Bodacious” and “Butter and Sugar”. what are they waiting for? I asked at the local market what type of corn they were selling and they looked at me like I was from New York City. I guess if you want that much information, you have to buy it at a farm stand. Highly recommended if you have one around.
And I was surprised to learn that although grain corn (the stuff they feed cows) dates back 8,000 years, the first evidence of sweet corn is thought to be from New York around 1600 and was most likely cultivated by the Iroquois Indians.
How to Buy Fresh Corn
The most important thing to remember when buying fresh corn on the cob is that it starts converting sweet tasting sugars to starches immediately after it is picked. So ideally you want to buy it, cook it and consume it the same day it is picked or as close to then as possible. I have read that sweet corn has an 80:20 sugar-starch ratio when harvested but within 3 days that ratio will shift to 20:80. That’s the difference between really sweet-tender corn and mealy tough corn.
When buying, pick up each ear and look for ears that feel full and plumb in your hand. Take a look at the silk sticking out at the top, it should be golden pale, slightly sticky, and the more the merrier.
Even though it’s sometimes messy and gets all over you when shucking, the more silk, the more kernels of corn. You also want the husks to have a good green color – not brown. Even though most stores don’t appreciate your doing this, try popping one of the kernels with your thumbnail. If the juice from the kernel is milky, the fresher the corn. And don’t buy corn that has been sitting out in the sun all day. The sun and heat will speed up that conversion of sugar to starch.
Look at the bottom of the ear of corn where it has been broken off at the stalk. If it has already turned brown, it most likely is at least 2 days old.
If you are not going to cook and eat your fresh corn that day, store it in the refrigerator with the husks left on. Cooling it will help slow down the sugar – starch transformation. You may also want to remove the long stem and outer most big leaves to prevent loss of moisture. Will it last more than a day? Sure it will but as the clock ticks, so does the sugar/starch ratio.
Prepping Fresh Corn – How to Shuck
Start by peeling the husk back from the top and
removing it completely. Remove all the thin hairs (silk) that run from top to bottom. If you are really fussy about those hairs, use a vegetable brush or a damp cloth. Finish up by breaking off the stalk at the bottom.
Cooking Fresh Corn on the Cob
There are many ways to cook fresh sweet corn. On top of your stove in a pot of water or steamer, on your grill, in your microwave (bad choice) and I’ve even tried cooking a large number of ears for a party in the dishwasher (but with wishy-washy results).
The most popular way to cook fresh sweet corn on the cob in our family is boiling it although my wife and I use different techniques to boil it and both come out great. She likes to start with a large pot of cold water, add the corn and bring to a boil. When the water comes to a rapid boil, the corn is done.
I learned as a kid to start by boiling the water first and then add the corn to it and let it cook for about 5 minutes. I don’t think it matters that much. Both ways always produce delicious corn. I have read in some cookbooks to add a teaspoon of sugar to the pot of water to keep the corn tender. I don’t think it will hurt, but if you are starting out with fresh sweet corn, why bother.
Cooking Do Not Do’s
- Don’t add salt to the water. It only toughens the corn when it cooks.
- Don’t cool off hot corn by running under cold water. It will make the corn soggy.
- Don’t overcook or the kernels will get hard and the corn will loose some of its sweet flavor.
Finishing it off
I suppose you can get “gourmet” and add all sorts of fancy seasonings but I like my sweet corn simple with just butter, salt, and pepper. Sometimes simple is better.
Applying the butter depends on whether we have guests or it’s just family. With guests, I cut a pat of butter and apply it with my knife or fork but when it’s just family, I will often roll it right on the stick of butter on the butter dish. (Oh, if my mom should read this newsletter!) This really gets the job done well but makes a mess out of the stick. It leaves that deep indentation making it look like a canoe.
My 4 and 6 year old daughters like to apply the butter with their hands. In fact I think the only reason they like corn – as a vehicle for butter.
One of my earliest childhood memories of eating corn is at my grandparents down at the Jersey shore. My grandmother always gave us kids those nifty corn holders that look like little ears of corn with two prongs sticking out that you would stick into the ends so you didn’t burn your fingers although inevitably someone always got stuck with the sharp prongs.
I also have a strong recollection of my grandfather cutting each row of corn kernels down the center with his knife to help him with digestion. As I’m writing this, I have to smile because the images are so clear. Corn on the cob is a real comfort food that you typically eat with family and friends so I can only suggest you find the last of the summer corn and create some great memories yourself.Source: www.reluctantgourmet.com
