Instructions:
- Prepare a pressure canner and keep clean jars hot until ready to fill.
- Husk the corn and remove all of the silk. Wash the ears thoroughly.
- Blanch the ears in boiling water for 3 minutes, then remove and drain.
- Cut the kernels from the cob, leaving about two-thirds of each kernel attached to help prevent excess starch.
- Fill the prepared hot jars with the corn, leaving 1 inch of headspace.
- If desired, add canning or pickling salt to each jar.
- Pour boiling water over the corn, maintaining 1 inch of headspace.
- Remove any air bubbles, adjust the headspace if needed, and wipe the jar rims clean.
- Apply the lids and bands until fingertip tight.
- Process the jars in a pressure canner:
- Pint jars: 55 minutes
- Quart jars: 85 minutes
- Adjust the pressure according to your altitude and the type of pressure canner you are using.
- Allow the pressure canner to depressurize naturally. Carefully remove the jars and let them cool undisturbed for 12–24 hours. Check that each lid has sealed before storing.
Variations
- Mix sweet corn with diced roasted peppers before serving for a colorful side dish.
- Add home-canned corn to black bean salsa for a fresh Southwestern flavor.
- Stir the corn into creamy chowders or vegetable soups for extra sweetness.
- Combine with diced potatoes and herbs when preparing casseroles.
- Season with butter, garlic, and fresh parsley after opening for a simple side dish.
Tips
- Harvest or purchase sweet corn as fresh as possible, ideally within a few hours of picking, for the sweetest flavor.
- Leave about one-third of each kernel on the cob when cutting to reduce excess starch in the jars.
- Salt is optional and used for flavor only; it is not required for safe preservation.
- Always follow the recommended pressure and processing times for your altitude and pressure canner model.
- Save the stripped corn cobs to make a flavorful homemade corn stock for soups, chowders, and sauces. Home-canned sweet corn is also delicious in chili, casseroles, cornbread, salads, salsa, and as a quick buttered side dish.
