The best way to store corn long term depends on the type of corn you have. There are different varieties of corn, each with its own characteristics and storage requirements. Let’s explore the different types and how to store them properly.
1. Dent Corn: Dent corn is commonly used to make masa or corn flour. It has a high starch content and a dent or indentation at the top of each kernel. Dent corn can last upwards of 20 years when stored correctly. To store dent corn long term, follow these steps:
– Ensure the corn is fully dried before storing. The moisture content should be around 12-15%.
– Remove the corn kernels from the cob if desired, or store the entire cob.
– Place the corn in airtight containers, such as Mason jars or food-grade buckets, to prevent moisture and pests from entering.
– Store the containers in a cool, dry place, away from direct sunlight. A basement or pantry works well.
– Check the containers periodically for signs of moisture or pests. If any issues are detected, transfer the corn to new containers and discard any contaminated kernels.
2. Dehydrated Sweet Corn: Dehydrated sweet corn is a popular option for long-term storage. It is made by removing the moisture from fresh sweet corn. Dehydrated sweet corn can last for a few years when stored properly. To store dehydrated sweet corn long term, follow these steps:
– Ensure the corn is fully dehydrated. It should be brittle and break easily.
– Place the dehydrated corn in airtight containers or vacuum-sealed bags to maintain its freshness.
– Store the containers in a cool, dry place, away from moisture and sunlight. A pantry or cupboard is suitable.
– Rehydrate the corn before using by soaking it in water for a few hours or boiling it until tender.
– Once rehydrated, use the corn in your favorite recipes as you would fresh corn.
3. Frozen Corn: Freezing corn is another excellent way to store it long term. Frozen corn can retain its quality for up to a year. To store corn in the freezer:
– Blanch the corn by boiling it briefly, then cooling it in ice water to stop the cooking process. This helps preserve the flavor, texture, and color.
– Remove the corn kernels from the cob if desired.
– Place the blanched corn in freezer bags or airtight containers, removing as much air as possible to prevent freezer burn.
– Label the containers with the date and store them in the freezer at 0°F (-18°C) or below.
– Use the frozen corn within a year for the best quality.
4. Canned Corn: Canning corn is another option for long-term storage. Canned corn can last for several years if properly sealed and stored. To can corn:
– Remove the corn kernels from the cob.
– Place the corn in sterilized canning jars, leaving about 1 inch of headspace.
– Add boiling water or a light sugar syrup to the jars, ensuring all the corn is covered.
– Wipe the jar rims clean, place lids and rings on tightly, following canning instructions.
– Process the jars in a pressure canner or water bath canner, depending on the acidity level of the corn.
– Store the sealed jars in a cool, dark place and use within a few years for the best quality.
By choosing the right type of corn and following the appropriate storage method, you can enjoy the flavors of corn for an extended period. Whether you opt for dent corn, dehydrated sweet corn, frozen corn, or canned corn, proper storage is key to maintaining its quality and taste.
