🍽 Key Ingredients

This sweet corn relish uses colorful fresh pantry vegetables and warming aromatic spices.

Vegetables - Using fresh produce for this relish will maximize the color and flavor. Use Fresh corn kernels, green, yellow, and red bell peppers, zucchini, and onions.

Vinegar - We're using 2 types: red wine vinegar to give the relish a beautiful vibrant red color and white vinegar for its strength.

Spices - The spices make a big difference to the overall taste, and ground turmeric, celery seed, and mustard seed are perfect aromatic spices for relish recipes.

Sugar - Use white granulated sugar as it dissolves better and doesn't change the corn mixture color, unlike brown sugar.

Salt - Use canning salt or pickling salt.

Substitutions

Vinegar

Apple cider vinegar is commonly used for relish recipes and is a perfect substitute for red wine vinegar. You can use apple cider vinegar as a 1:1 substitution.

Salt

You can use kosher salt as a substitute for canning salt as long as it doesn't contain anti-caking chemicals. Use the conversion of 1 teaspoon of canning salt to 1 ¼ teaspoon of kosher salt.

🔪 How to make

This zucchini, sweet corn relish recipe is super easy to make using this canning method. Once the relish mixture has been cooked, it is transferred to tightly sealed jars and processed in the canner.

Preparations

Step 1
Without removing the peel, chop the zucchini into small pieces with a knife.

Step 2
Chop one large red pepper, one yellow pepper, and one green pepper. I don't have a photo of a green pepper but I'm getting a ton of them out of the garden this year. Also, chop 3 medium size onions.

Step 3
You will also need about 4-5 ears of corn. Use a knife to cut the kernels from the cobs.

Cooking Instructions

Step 1
Place all of the chopped veggies in a large bowl. Sprinkle ½ cup canning salt on the top and then add enough cold water to the bowl to cover the veggies. *Note: do not use regular salt because the additives in regular salt will make a cloudy mixture. 

Step 2
Cover and allow to stand at room temperature for 3 hours.

Step 3
Transfer vegetable mixture to a large colander set in the sink. Rinse with cold water and drain.

Step 4
In an 8-10 quart heavy pot, combine red wine vinegar, white vinegar, water, sugar, mustard seeds, celery seeds, and turmeric and bring to a boil. Stir until the sugar dissolves, reduce heat, and simmer for 3 minutes.

Step 5
Add the drained vegetable mixture and return to a boil. Reduce the heat again, and simmer, uncovered, for about 10 minutes, stirring occasionally.

Step 6
Ladle into hot, sterilized pint jars, leaving a ½-inch headspace. Remove any air pockets, wipe rims, and apply prepared lids and rings. Tighten rings just until fingertip-tight.

Step 7
Place jars in a boiling water canner and process for 15 minutes. Turn off the canner and let the jars stand in water for 5 minutes. Transfer jars to a towel-lined surface and let rest at room temperature until cooled. Check seals and store in a cool, dark place.
