Learn More About Corn
In the olden days, cooks put a pot of water on to boil before heading out to harvest their corn – and for good reason. Sweet corn starts to convert its sugar to starch immediately after it is removed from the stalk. The sooner you cook it, the sweeter the taste and more tender the bite.
The sugars in today’s hybrid varieties of corn are slower to turn to starch, which buys you some time. No matter which variety you select, opt for freshness. Look for husks that are tight to the ear, moist and bright green with soft, golden silks. Peek under the husk to be sure the kernels are plump and packed tightly. Large kernels at the end of the ear are a sign of over-maturity.
Keep the husks on the ears and refrigerate until you are ready to cook your corn. Standard sweet corn should be eaten the same day it is harvested. Sugar-enhanced and super-sweets can be kept in the refrigerator for two to three days, wrapped in a moist paper bag.
To cook, heat a large pot of water. Do not salt the water as it toughens the kernels. When the water boils, add the shucked corn. Let the water return to a boil, then turn off the heat and enjoy your corn.
Preparation for grilling corn takes a little more effort. Peel back the husks, remove the silks and pull the husks back up. To keep the husks from burning, put the ears in a tub of water for a few minutes. Drain, and then grill over a medium-low fire for 10 to 15 minutes. For extra flavor, pull back the husks and return the corn to the grill for a few minutes of browning.
To turn an ear into kernels, use a sharp knife and a sawing motion to cut off the top half of the corn kernels. Next, turn the knife over to the dull side and scrape down the cob to get the full essence of corn.Peggy Crum MA, RD
