- 1 small sweet onion (such as Vidalia), halved and thinly sliced
- 1 small red onion, halved and thinly sliced
- 1 cup white-wine vinegar
- 1/2 cup sugar
- 1 tablespoon coarse salt
- 1 bunch scallions, cut into 2-inch lengths and slivered lengthwise
- Ground pepper
In a medium bowl, combine sweet and red onions; add ice water to cover. Soak for 30 minutes, changing ice water once. Drain onions well, and return to empty bowl. In a medium saucepan, bring vinegar, sugar, and salt to a boil, stirring until sugar is dissolved; pour over onions, and set aside to cool, tossing occasionally. When cool, stir in scallionos. Season with pepper.
