Canning corn is a delightful way to preserve the sweet, juicy essence of summer and enjoy it all year round. Whether you have an abundance of fresh corn from the farmers’ market or your own garden, canning allows you to capture that freshness for later use. If you don’t own a pressure cooker, fear not! You can still successfully can corn using water bath canning methods. This guide will walk you through the entire process, ensuring that your canned corn is both safe and delicious.
Understanding the Basics of Canning Corn
Canning is a method of preserving food that involves sealing it in airtight containers to prevent spoilage. The critical point to remember is that corn is classified as a low-acid food, which means it requires proper canning techniques to prevent the growth of harmful bacteria like botulism. For those using a pressure cooker, processing corn is relatively straightforward. However, if you prefer or need to use water bath canning, specific methods must be followed closely to ensure safety.
Essential Supplies for Canning Corn
Before you begin the canning process, gather your supplies. Having everything organized will make the task easier and more efficient.
Equipment You Will Need
- Canner or large pot with a lid
- Jars (pint or quart size)
- New lids and bands
- Canning funnel
- Jar lifter or tongs
- Slotted spoon
- Kitchen towel
- Large bowl or pot for blanching
- Timer
Ingredients
- Fresh corn (approximately 6 to 7 ears for a quart jar)
- Water
- Salt (optional, for flavor)
Preparing Your Corn
To ensure the best quality and flavor in your canned corn, proper preparation is key. Follow these steps to get your corn ready for canning.
Choosing the Right Corn
Select sweet corn that is at its peak ripeness. Look for ears that are plump, with bright green husks and tightly packed kernels. The kernels should be milky and juicy. Younger, fresher corn will yield a better flavor in your canned goods.
How to Husk, Clean, and Cut Corn
- Begin by husking your corn. Remove all green husks, silk, and any blemished or damaged kernels.
- Rinse the corn under cool running water to remove any remaining dirt and silk.
- Using a sharp knife, cut the kernels off the cob, being careful not to cut too deep into the cob as this can make the final product taste rough.
Blanching the Corn
Blanching is crucial as it helps retain the flavor, color, and texture of the corn while eliminating surface bacteria. Here’s how to do it:
- Bring a large pot of water to a rolling boil.
- Add the cut corn to the boiling water and blanch for 4-5 minutes.
- Remove the corn from the boiling water using a slotted spoon and immediately transfer it to a bowl of ice water. This process stops the cooking and helps maintain the corn’s crispness.
The Canning Process: Steps to Follow
Now that your corn is prepped, it’s time to start canning! Below is a step-by-step guide to can corn using a water bath canning method.
Cleaning and Preparing Jars
- Start by sterilizing your jars. You can do this by placing them in a boiling water bath for 10 minutes.
- Let the jars cool before filling them with corn. Ensure the lids are also clean and free from any impurities.
Filling the Jars
- Using a canning funnel, fill each jar with the blanched corn, leaving about 1-inch headspace at the top.
- If you like a little extra seasoning, add 1/2 teaspoon of salt for pints or 1 teaspoon for quarts.
- Carefully pour boiling water over the corn, again leaving a 1-inch headspace.

Checking the Seals
After 24 hours, it’s essential to check that each jar has sealed properly.
- Press down in the center of each lid. If it doesn’t pop back, the jar has sealed well.
- If a jar hasn’t sealed, you can refrigerate it and consume the corn within a few days.
Tips for Successful Canning of Corn
- Use Fresh Corn: The fresher the corn, the better the flavor and texture of your canned product.
- Avoid Overcrowding Jars: Ensure jars have enough headspace as this helps in generating a proper vacuum seal.
- Keep Everything Clean: Sanitation is vital in canning; always work with clean utensils and jars to avoid contamination.
Storing Your Canned Corn
Once your jars have cooled and sealed properly, it’s time to store them.
Proper Storage Conditions
- Store your canned corn in a cool, dark place. A pantry or cellar is ideal.
- Make sure that they are placed on a sturdy shelf away from direct sunlight and heat sources.
Using Your Canned Corn
Canned corn can be used in a variety of dishes, from soups and casseroles to salads and salsas. Its versatility makes it an excellent addition to your pantry.
