Nutrition Information
Sweet corn is a good source of many nutrients. A medium-sized ear of corn has about 75 calories and one gram of fat. It supplies carbohydrates, protein, and potassium, and is a good source of dietary fiber. Other nutrients include thiamin (vitamin B1), pantothenic acid (vitamin B5), folate, dietary fiber, vitamin C, phosphorous, and manganese. Corn also contains beta-carotene, and is a useful source of protein.
Selection
Freshness and cool storage after harvest are the secrets to getting good quality corn when shopping. When held in warm temperatures, the sugar in the corn changes to starch. Corn will taste less sweet. Super-sweet varieties hold the sugar content longer than regular corn varieties. When buying corn, look for ears stored in refrigerated bins at local stores or held in the shade or on ice at farmers’ markets or roadside stands. Choose corn that is picked daily. Shop early in the day to get the freshest ears. Look for husks that are tight, green, and fresh-looking. The stalk should be green and moist and the silk still moist, soft, and light in color.
Storage
Corn is best if cooked and eaten within a few hours of picking, so try not to store it long if possible. If you do have to store corn, leave it in the husk until you are ready to cook it. Storing corn in a perforated plastic bag in the crisper of your refrigerator is best.
Preparation
Corn is very versatile, and can be prepared many ways. Sweet corn can be prepared in or out of the husk using a variety of methods. Fresh corn from the garden is usually left on the cob, but cutting kernels off the cobs is an option.
Boiling or Steaming: After husking, cook corn by placing ears upright in a stockpot with 1 to 11/2 inches of water. Cover the pot and let it steam for about seven minutes after boiling begins. Or lay ears in a pan, with two to three quarts of water. To sweeten the pot, add about three tablespoons of sugar, and boil for about four minutes. Adding salt to the water can make the corn firmer. Do not overcook.
Microwaving: Corn can also be microwaved in or out of its husk. For the best flavor, remove the outer husks, letting the inner husks remain. After microwaving, pull the husks downward to remove them along with the silk. Or husk and clean each ear, wrap it in waxed paper or plastic wrap or place in a glass dish with a cover, and cook for about two minutes per ear.
Roasting/Grilling: You can grill sweet corn in the husk or out of it. For a milder flavor, soak the corn in husks in cold water, then place them on a hot grill and cook until they’re evenly heated on all sides — from 10 to 15 minutes. Husking first gives a much more intense grilled-corn flavor, and will only take five to seven minutes. Turn occasionally to expose all surfaces to the heat. Open fire pits allow you to bury the ears in coals. Wrap them in several layers of foil and cover with coals for 10 to 15 minutes.
Corn Storage:
Store corn for up to 5 days in fridge. Use as soon as possible for the best flavor. Store cooked corn in the refrigerator for up to a week.
Nutrition: Corn is a whole grain. It is high in fiber and Vitamin B1.
Dark spots and worms occasionally appear in corn. Cut off these areas and use the rest of the corn.
