Nothing beats the taste of fresh sweet corn. And with a few jars and some know-how, you can keep that summer sweetness in your pantry long after the harvest. Whether you've got a garden full of corn or found a great deal at the farm stand, I'll show you how to save every delicious kernel.
Getting Your Kitchen Ready
First, let's get your canning corner set up. You'll need:
- A pressure canner - this is crucial for corn
- Clean jars and new lids
- A jar lifter (those jars get mighty hot)
- A funnel to keep things tidy
- The freshest corn you can find
- Some canning salt if you like
- A big pot of boiling water
Why the Pressure Canner?
Here's the deal - corn needs super-high heat to be safe for storing. A regular water bath just won't do it. Think of your pressure canner as insurance for all your hard work.
Rolling Up Your Sleeves
- Step 1: Prepare the corn
- Strip off every bit of husk and silk, making sure the ears are completely clean. Then, carefully cut the kernels off the cob, aiming for about half an inch deep. This keeps the kernels intact and prevents getting too much of the tough cob.
- Step 2: Choose your packing method
- If you’re in a hurry, go for the raw pack method by simply packing the fresh kernels directly into jars. For a slightly richer flavor, try the hot pack method by boiling the kernels for 3-5 minutes before packing them into jars.
- Step 3: Fill the jars
- Leave an inch of space at the top of each jar. This allows the corn to expand during processing. Add a bit of salt for flavor—about half a teaspoon per pint jar—then pour boiling water over the corn until it reaches the one-inch mark. Wipe the rims clean, place the lids on, and tighten the rings just finger-tight.
- Step 4: Process the jars
- Carefully lower the jars into your pressure canner, making sure they’re not touching each other. Follow the processing times exactly: pints need 55 minutes, while quarts require 85 minutes. Adjust the pressure to 10-15 pounds based on your altitude. Check your canner’s manual for specific details.

This vibrant salsa is a snack-time favorite. Combine the following ingredients:

Making Your Corn Last
Find a cool, dark spot for your jars—like a basement shelf. Properly canned corn can last up to 18 months, though it’s so tasty it rarely stays on the shelf that long! Before opening a jar, check that the lid is tight and slightly curved downward.
