Ingredients:
- 8 cups fresh sweet corn, shucked and cut from the cob
- 1 cup red bell pepper, finely diced
- 1 cup green bell pepper, finely diced
- 1.5 cups Vidalia or sweet onion, finely diced
- 1 large jalapeño, seeded and minced
- 2.5 cups apple cider vinegar (5% acidity)
- 1.5 cups white granulated sugar
- 2 tablespoons pickling salt
- 2 teaspoons mustard seeds
- 1 teaspoon celery seeds
- 0.5 teaspoon ground turmeric
- 1 teaspoon dry mustard powder
Instructions:
- Prep all vegetables (corn, peppers, and onion) into a uniform 1/4-inch dice to ensure even cooking and consistent texture.
- In a large non-reactive stockpot (stainless steel or enamel-coated), combine the apple cider vinegar, sugar, salt, mustard seeds, celery seeds, turmeric, and mustard powder.
- Bring the mixture to a rolling boil over medium-high heat, stirring until the sugar is completely dissolved. Let the brine boil for 3 minutes to bloom the spices and concentrate flavor.
- Add the diced corn, peppers, onion, and jalapeño to the boiling brine. Return to a simmer.
- Simmer for 15 minutes. Use a high-heat, short-duration simmer to prevent the corn’s cell walls from collapsing, maintaining a signature 'pop'.
- Remove from heat. Ladle the hot relish into prepared canning jars or allow to cool before refrigerating for immediate use.
