A medium ear of corn contains about 90 calories and 3 grams of protein. It’s an excellent source of vitamin C, thiamin, and folate.

Corn also offers antioxidants like lutein and zeaxanthin, which promote eye health. The fiber content aids digestion and helps maintain steady blood sugar levels.

Popular Corn on the Cob Dishes

Corn on the cob can be enjoyed in many forms. Grilled corn is a summer favorite, often brushed with butter and seasoned with salt and pepper.

Mexican-style elote features corn topped with mayo, cheese, chili powder, and lime juice. Corn chowder is a creamy soup perfect for colder months.

Corn fritters make a tasty appetizer or side dish. Fresh corn kernels can be added to salads or used to make corn salsa for a refreshing twist.

Proper Storage Techniques

Properly storing corn on the cob helps maintain its freshness and flavor. The right methods can extend shelf life and preserve quality.

Using Airtight Containers

Airtight containers provide an effective barrier against moisture and contaminants. For leftover corn on the cob, place cooled ears in a plastic or glass container with a tight-fitting lid. Remove as much air as possible before sealing to prevent freezer burn.

For cooked corn on the cob, let it cool completely before storage. Cut large ears in half if needed to fit the container. Add a damp paper towel to maintain moisture levels.

Label containers with the date of storage. This helps track freshness and ensures older corn is used first.

Refrigeration Best Practices

Refrigeration slows down the conversion of sugars to starch in corn, preserving its sweetness. Store fresh corn with husks intact in the crisper drawer. If husked, wrap ears in damp paper towels and place in a plastic bag.

For cooked corn on the cob, refrigerate within two hours of cooking. Place in airtight containers or wrap tightly in aluminum foil or plastic wrap. Properly stored, cooked corn on the cob lasts 3-5 days in the refrigerator.

Check corn regularly for signs of spoilage like mold or off-odors. Discard any corn that shows these signs.

Freezing Cooked Corn on the Cob

Freezing extends the storage life of cooked corn on the cob for several months. Blanch fresh corn before freezing to preserve texture and flavor. For already cooked corn, cool completely before freezing.

Wrap individual ears tightly in plastic wrap or aluminum foil. Place wrapped ears in freezer bags, removing as much air as possible. Label bags with the date of freezing.

To prevent freezer burn, double-wrap corn or use vacuum-sealed bags. Frozen corn on the cob maintains best quality for up to 12 months. Thaw in the refrigerator before reheating.

Safety and Quality of Leftover Corn

Proper handling and storage of leftover corn is crucial for maintaining its safety and quality. Knowing the signs of spoilage and adhering to recommended consumption timelines can help prevent foodborne illness.

Identifying Spoilage

Leftover corn can spoil quickly if not stored properly. Look for visual cues such as mold growth, which appears as fuzzy spots in various colors. A slimy texture or an off-putting odor are also indicators of spoilage.

Changes in color, such as brown or black spots, suggest the corn is past its prime. Taste can be a final indicator – if the corn tastes sour or unpleasant, discard it immediately.

Bacteria growth is a serious concern with leftover corn. While not always visible, it can cause foodborne illnesses. If corn has been left at room temperature for more than 2 hours, it’s safest to throw it away.

Leftovers Consumption Timelines

Cooked corn on the cob can be safely stored in the refrigerator for 3-5 days. Place it in an airtight container or wrap it tightly in plastic wrap or aluminum foil to maintain freshness.
