Neiman Marcus' Northpark Corn Relish - cooking recipe

Ingredients

4 cups corn kernels
1 1/2 cups onions, finely diced
1/2 cup red bell pepper, seeded and finely diced
1/2 cup sugar
1 cup vinegar, cider
1 1/2 teaspoons salt
1/2 teaspoon celery seed
1/2 teaspoon mustard powder
2 tablespoons parsley, chopped (flat-leaf preferred)

Preparation

Place the corn, onions, and bell pepper in a heavy-bottomed saucepan.
In a mixing bowl, whisk together the sugar, vinegar, salt, celery seed, and mustard powder until the sugar and mustard are dissolved.
Pour the vinegar mixture over the vegetables in the pan and bring to a simmer over medium-high heat.
Turn the heat down to medium-low and simmer, uncovered, for about 1 hour, until the liquid has just evaporated and the relish has an attractive sheen; be careful not to allow it to burn.
Let the relish cool.
Add the parsley and mix well.
Serve immediately or cover the bowl and keep refrigerated until ready to use.
