Canning corn is a wonderful way to preserve its garden-fresh flavor and enjoy it year-round. By following a few simple steps, you can have a pantry stocked with delicious canned corn, ready to be used in your favorite recipes. In this article, we’ll outline the steps necessary to successfully can corn at home.

Materials Needed:

– Fresh corn on the cob

– A large pot for boiling water

– A smaller pot for heating lids

– Canning jars with lids and rings

– Tongs or a jar lifter

– A clean towel and paper towels

– A canning funnel (optional)

– A pressure canner

Step 1: Choose and Prep the Corn

Pick out fresh, sweet corn from your local farmer’s market or grocery store. The ideal time for canning corn is when the kernels are plump and tender. Husk the corn, removing any silk, and wash it thoroughly.

Step 2: Blanch the Corn

Place the shucked corn in a pot of boiling water for about 3 minutes. This process helps to kill enzymes that may cause spoilage during storage. Once blanching is complete, quickly cool the ears of corn in a bowl of ice water for 3 minutes as well.

Step 3: Remove Kernels from Cobs

Using a sharp knife or corn cutter, carefully cut the kernels from the cobs. Be sure not to include any cob material while cutting.

Step 4: Prepare the Jars

Wash and sterilize your canning jars in hot soapy water or by placing them in a large pot of boiling water for a few minutes. Lay a clean towel on your countertop and place your sterilized jars on it to let them dry.

Step 5: Pack the Jars with Corn

Once the jars are dry, use tongs or your hands to pack the corn into the jars. Leave about 1 inch of headspace at the top of each jar. Avoid packing the corn too tightly, as it may expand during processing.

Step 6: Add Liquid

Corn can be canned using either water or a mixture of water and sugar. Fill each jar with your chosen liquid, leaving 1 inch of headspace. Use a bubble remover or a non-metallic utensil to release any air bubbles by running it along the inside edge of the jar.

Step 7: Seal the Jars

Wipe the rims of each jar with a clean, damp paper towel to remove any residue. Place a sterilized lid on each jar, then screw the metal ring securely in place.

Step 8: Pressure Canning

Canned corn requires a pressure canner for proper preservation since it is a low-acid food. Follow your pressure canner’s instructions to process the jars at 10-15 PSI depending on your altitude, typically for about 85-100 minutes.

Step 9: Cooling and Storage

After processing, carefully remove the jars from the canner and let them cool for 12-24 hours on a towel-covered countertop. Finally, check that all jars have sealed properly by pressing down on the center of each lid – if there’s no movement or pops, it’s sealed. Store your canned corn in a cool, dark place for up to one year.

With these steps, you’re now equipped with all you need to know about canning corn at home. It’s an easy way to preserve its delicious flavor and make it readily available whenever you need it – plus, it can save you money compared to store-bought canned corn!
