Ingredients
3 ears corn, husks and silks removed
Kosher salt
2/3 up white-wine vinegar, plus more if needed
1/4 cup light-brown sugar
2 teaspoons mustard seeds
2 teaspoons coriander seeds
1/2 cup diced sweet onion, such as Vidalia
2 celery stalks, diced (2/3 cup)
1 red bell pepper, ribs and seeds removed, diced (2/3 cup)
1 jalapeño or serrano pepper (ribs and seeds removed for less heat, if desired), minced
Preparation
Cook corn in a large pot of generously salted boiling water until crisp-tender, about 2 minutes. Drain; let cool completely. Strip kernels from cobs with a sharp knife.
Meanwhile, combine vinegar, 1/3 cup water, brown sugar, mustard and coriander seeds, and 1 teaspoon salt in a saucepan. Bring to a boil over medium-high heat, stirring until sugar dissolves. Stir in onion, celery, and bell pepper. Reduce heat to medium-low; simmer until vegetables are crisp-tender, about 5 minutes. Stir in corn kernels and jalapeño; simmer 1 minute more. Carefully transfer mixture to a 4-cup-capacity or two 2-cup-capacity jars. Top with more vinegar, if necessary. (Liquid should fully submerge corn mixture and reach about 1/2 inch from top.) Let cool completely, then cover and refrigerate until ready to use, up to 1 month or can with our helpful instructions.
