Gather Your Supplies
Before starting the canning process, it’s essential to gather all the necessary supplies to ensure a smooth operation. Here’s what you’ll need:
- Do not use a boiling-water bath for this food; low-acid foods must be pressure canned following a tested recipe.
- Jars (quart or pint-sized, depending on your preference)
- Lids and bands (make sure they are new for a proper seal)
- Large pot for blanching corn
- Large bowl for ice water
- Colander for draining
- Cutting board and sharp knife for cutting corn
- Measuring cups and spoons
- Kitchen towel for wiping jar rims
- Jar lifter and funnel for easy filling
- Timer for precise cooking times
Food safety note: Vegetables, beans, meat, poultry, soups and stocks are low-acid foods. For shelf-stable jars they must be processed in a pressure canner, never in a boiling-water bath, oven or by any other method, because under-processing can cause botulism. Use the exact jar size, headspace, pressure and processing time from a tested recipe from the National Center for Home Food Preservation (nchfp.uga.edu) or the USDA Complete Guide to Home Canning, adjusted for your altitude. Without a pressure canner, refrigerate and use within 3–4 days or freeze instead.
Preparing the Corn
Once you have your supplies ready, it’s time to prepare your corn. Here’s a step-by-step process:
- Select Fresh Corn: Choose sweet corn that is fresh, tender, and free of blemishes. The best time to can corn is during peak season when it’s at its sweetest.
- Shuck the Corn: Remove the husks and silk from the corn. This step is crucial as it ensures that you’re left with only the kernels.
- Blanch the Corn: Fill a large pot with water and bring it to a boil. Once boiling, add the corn for 4-6 minutes. Blanching helps preserve the color, flavor, and texture of the corn.
- Cool the Corn: After blanching, immediately transfer the corn to an ice water bath to stop the cooking process. Let it cool for about 5 minutes.
- Cut the Kernels: Once cooled, place the corn on a cutting board. Use a sharp knife to cut the kernels off the cob. Aim for about 1 inch from the base of the kernels to minimize waste.
Packing the Jars
Now that your corn is prepared, you can begin packing it into jars. Follow these steps for optimal results:
- Sterilize Your Jars: Before packing, ensure your jars are sterilized by placing them in a boiling water bath for 10 minutes or running them through a dishwasher cycle without soap.
- Fill the Jars: Using a funnel, pack the corn into the jars, leaving about 1 inch of headspace at the top. This space is important for the expansion of the food during the canning process.
- Add Salt (Optional): If desired, add 1 teaspoon of salt per quart jar or ½ teaspoon per pint jar for flavor. This is an optional step, but it can enhance the taste of your canned corn.
- Add Water: Pour boiling water over the packed corn, ensuring that the kernels are completely submerged while maintaining the headspace.
- Remove Air Bubbles: Use a non-metallic spatula or a bubble freer to gently press down on the corn and release any trapped air bubbles. This step is crucial for ensuring a proper seal.
- Wipe Jar Rims: Take a clean kitchen towel and wipe the rims of the jars to remove any residue or moisture. This helps create a better seal.
- Apply Lids and Bands: Place a lid on each jar and screw on the bands until they are fingertip-tight. Avoid over-tightening, as this can hinder the sealing process.
Canning Process
With your jars filled and ready, it’s time to process them. Do not use a boiling-water bath for this food; low-acid foods must be pressure canned following a tested recipe.
Do not use a boiling-water bath for this food; low-acid foods must be pressure canned following a tested recipe.
- Do not use a boiling-water bath for this food; low-acid foods must be pressure canned following a tested recipe. Bring the water to a simmer.
- Process the Jars: Carefully place the jars into the canner using a jar lifter. Ensure that they are not touching each other. Cover the canner with the lid and bring the water to a rolling boil.
- Timing: Process pint jars for 55 minutes and quart jars for 85 minutes, adjusting for altitude if necessary.
- Cool Down: After processing, turn off the heat and let the jars sit in the canner for 5 minutes. Then, carefully remove the jars and place them on a clean towel or cooling rack to cool completely.
Pressure Canning
- Prepare the Canner: Add about 2-3 inches of water to the bottom of the pressure canner and place the jar rack inside.
- Heat the Canner: Lock the lid in place and bring the canner up to the required pressure (usually 10-15 pounds depending on your altitude and instructions).
- Process the jars at the pressure and for the time given in a tested recipe from the National Center for Home Food Preservation (nchfp.uga.edu) for your jar size and altitude.
- Cooling Down: Once processing is complete, turn off the heat and allow the canner to depressurize naturally. Once the pressure gauge reads zero, carefully remove the lid and let the jars cool.
Checking Seals and Storing Your Canned Corn
After your jars have cooled, it’s time to check the seals and store your beautifully canned corn:
- Check the Seals: Press down in the center of each lid. If it doesn’t pop back, the jar has sealed properly. If it pops back, the jar has not sealed and should be refrigerated and used within a few days.
- Label Your Jars: Using a permanent marker or label maker, write the date and contents on each jar. This helps keep track of freshness.
- Store in a Cool, Dark Place: Ideal storage conditions include a pantry or cupboard away from sunlight. Properly sealed jars can last for up to a year.
Conclusion
Canning corn is a rewarding process that allows you to enjoy the flavors of summer all year round. By following these steps, you can ensure perfect preservation, maintaining the taste and texture of your corn. Remember to always practice safe canning techniques and enjoy your homemade corn in soups, salads, or as a side dish. Happy canning!

Storing Your Canned Corn
Once your corn is successfully canned, proper storage is essential for maintaining its quality. Here are some tips on how to store your jars:
- Cool Down: Allow the jars to cool completely at room temperature before moving them to storage. This helps to ensure that the seals form properly.
- Label and Date: Use masking tape or labels to mark each jar with the contents and the date of canning. This will help you keep track of freshness and rotation.
- Store in a Cool, Dark Place: Find a cool, dark area in your pantry or kitchen for storing your canned corn. The ideal temperature is between 50-70°F (10-21°C).
- Avoid Humid Areas: Steer clear of storing jars in humid areas such as above the stove or near the dishwasher, as moisture can compromise the seals over time.
- Check Regularly: Periodically check your stored jars for any signs of spoilage, such as bulging lids or off-smells. If you notice anything unusual, discard the jar immediately.
Using Leftover Corn
If you find yourself with leftover corn after your canning session, don’t let it go to waste! Here are a few creative ways to use it:
- Freezing: If you have excess corn, consider freezing it. Blanch the corn first, then cool it down before placing it in freezer bags for later use.
- Soups and Stews: Add leftover corn to soups and stews to enhance flavor and nutrition. It pairs well with chicken, potatoes, and beans.
- Corn Salsa: Combine leftover corn with diced tomatoes, onions, cilantro, and lime juice for a refreshing corn salsa that’s perfect for snacking.
