This easy homemade sweet corn relish canning recipe combines fresh corn, colorful bell peppers, onion, 5% acidity vinegar, sugar, and warm spices into a tangy-sweet relish that is perfect for burgers, hot dogs, grilled meats, sandwiches, and summer salads. The recipe makes about 4 pints or 8 half-pints and uses a 15-minute boiling-water-bath process at elevations up to 1,000 feet.
Each spoonful has tender-crisp corn, a pleasant vinegar bite, gentle sweetness, and a bright crunch from red and green peppers. Follow the tested ingredient ratio closely, especially the vinegar quantity, because corn is a low-acid food and safe shelf-stable canning depends on the specified acidity and processing instructions.

This sweet corn relish is one of those pantry recipes that makes everyday meals taste more colorful and complete. It brings together crisp corn, peppers, and onion with a bright vinegar base, while sugar rounds out the sharpness without making the relish taste like dessert.
The red and green peppers add beautiful color to every jar, and the celery seed and mustard seed contribute a savory, lightly spiced finish. The texture is especially appealing because the vegetables are simmered only until tender while retaining a little bite.
- Uses fresh corn or thawed, drained frozen corn.
- Makes about 4 pint jars or 8 half-pint jars.
- Works beautifully with grilled foods, sandwiches, beans, and picnic dishes.
- Requires about 15 minutes of boiling-water-bath processing at 0–1,000 feet.
Serve it alongside a casual family meal with this cheeseburger dip for a generous snack table, or spoon it over grilled sausages and hot dogs for a fresh, tangy topping.
Ingredients You’ll Need
Start with 4 cups of fresh corn kernels, which usually come from 6–8 ears. Choose tender corn with plump kernels, and cut them from the cob without scraping deeply; scraping can pull starchy material from the cob and change the relish texture.
You will also need 1 cup each of finely chopped red bell pepper, green bell pepper, and onion. Dice these vegetables as evenly as possible so every bite cooks at the same rate and each jar has a balanced mix of colors.
The preserving mixture contains 2 cups of apple-cider vinegar or white vinegar labeled 5% acidity, 1 cup granulated sugar, 1 tablespoon canning or pickling salt, 1 teaspoon celery seed, and 1 teaspoon mustard seed. The vinegar quantity and acidity are essential, so do not substitute a lower-acidity vinegar, reduce the vinegar, or increase the vegetables.
If fresh corn is unavailable, frozen corn is acceptable when thawed and drained first. Have clean pint or half-pint jars, prepared lids, screw bands, a jar lifter, a canning funnel, and a large boiling-water canner ready before cooking begins.
For a sweet finish after dinner, keep the jars company with cinnamon maple muffins. Their warm maple flavor is a lovely contrast to the relish’s crisp, vinegary bite.
How to Make It Step-by-Step
Step 1: Prepare the boiling-water canner and place the jars inside to keep them hot. Prepare the lids according to the manufacturer’s directions, and keep the bands nearby so the hot relish can be packed without delay.
Step 2: Husk the corn and remove all visible silk. Use a sharp knife to cut the kernels from the cobs, taking care not to scrape deeply after the kernels are removed; the goal is a clean, tender kernel rather than a starchy cob scraping.
Step 3: Finely chop the red bell pepper, green bell pepper, and onion. Uniform pieces give the finished relish an attractive appearance and help the vegetables become tender at a similar pace.
Step 4: Add the corn, both peppers, onion, vinegar, sugar, salt, celery seed, and mustard seed to a large stainless-steel or enameled pot. Stir thoroughly so the sugar and salt begin to dissolve and the vegetables are evenly coated.
Step 5: Bring the mixture to a boil over medium-high heat, stirring frequently to prevent sticking and distribute the vegetables. Once boiling, reduce the heat and simmer for about 10 minutes, or until the vegetables are tender but still slightly crisp.
Step 6: Using a jar lifter, remove one hot jar at a time and place it on a towel or work surface. Ladle the hot relish into the jar, leaving 1/2 inch headspace, then remove trapped air bubbles with a nonmetallic bubble remover or clean utensil.
Step 7: Wipe each jar rim carefully with a clean damp cloth because even a small amount of relish can prevent a good seal. Apply the prepared lid and screw the band fingertip-tight rather than forcing it tightly.
Step 8: Place the filled jars into the boiling-water canner, ensuring the water covers the jars as required by your canning authority. Process pint or half-pint jars for 15 minutes at elevations up to 1,000 feet, increasing the processing time according to the appropriate elevation chart.
Step 9: Turn off the heat and remove the jars carefully after processing. Set them upright on a towel where they can cool undisturbed for 12–24 hours, then check each seal and refrigerate any jar that did not seal.
Pro Tips for the Best Texture and Flavor
Fresh, tender corn produces the sweetest and most pleasant texture, but thawed and drained frozen corn is a practical substitute. Avoid overcooking the vegetables because the relish should retain a gentle crunch rather than becoming soft and jammy.
Uniform chopping is more than a presentation detail. Similar-sized pieces allow the peppers and onion to cook evenly, and they make it easier to distribute corn, color, and spices throughout every jar.
Stir often while bringing the mixture to a boil and during the simmer. The sugar can settle, so regular stirring helps prevent scorching and keeps the vinegar mixture evenly distributed.
Do not alter the safe canning ratio. In particular, do not reduce the 2 cups of 5% acidity vinegar or add more vegetables, since the acid level is important for shelf-stable storage.
For another corn-centered serving idea, try this relish with spicy honey cornbread muffins. The sweet heat of the muffins pairs naturally with the crisp, tangy relish.
Canning, Cooling, and Storage
Keep the jars hot before filling to help prevent thermal shock. Once filled, leave 1/2 inch headspace, remove air bubbles, clean the rims, and apply the lids and bands correctly.
At elevations from 0–1,000 feet, process pints or half-pints for 15 minutes in a boiling-water canner. At higher elevations, use the adjustment chart supplied by your canning authority rather than guessing at a longer processing time.
After processing, cool the jars undisturbed for 12–24 hours. Press the center of each lid to check the seal, and refrigerate any jar that has not sealed properly.
Although a sealed jar can be stored as directed for shelf stability, the relish generally tastes better after standing for at least 24 hours. This resting time allows the vinegar, sugar, mustard seed, celery seed, corn, peppers, and onion to blend into a more rounded flavor.
Once opened, refrigerate the jar and use clean utensils each time. The relish is delicious straight from the refrigerator, so no reheating is needed.

Ways to Serve Sweet Corn Relish
Spoon the relish over grilled hot dogs, bratwurst, burgers, pulled pork, or grilled chicken. The vinegar cuts through rich foods while the corn and peppers add a fresh, lightly sweet crunch.
It also belongs on picnic plates beside potato salad, baked beans, coleslaw, and deviled eggs. A tablespoon stirred into tuna salad, egg salad, or creamy chicken salad adds color and a bright contrast.
- Top tacos, nachos, or grilled fish with a spoonful.
- Fold a small amount into a bean salad or chilled pasta salad.
- Serve with crackers and soft cheese as an easy appetizer.
- Add it to a sandwich for crisp texture and tang.
Because the relish is already seasoned, start with a small amount and add more to taste. Its sweet-tart flavor can transform simple leftovers into a quick lunch.
For a sweet homemade treat to finish the meal, serve a few peanut butter cups after the savory spread.

- Process the jars in a boiling-water canner for 15 minutes at elevations up to 1,000 feet. Adjust the processing time according to the elevation chart used by your canning authority.
- Let the jars cool undisturbed for 12–24 hours. Check the seals, refrigerate any unsealed jars, and allow sealed relish to stand for at least 24 hours before opening for the best flavor.
