Glazed Radishes

Cut large radishes in half; leave small ones whole. In a 12-inch skillet, combine radishes, butter, sugar, vinegar, 1 teaspoon salt, 1/4 teaspoon pepper, and 1 1/2 cups water. Bring to a boil over high heat; cook, stirring occasionally, until liquid has reduced and radishes are tender and glazed, 10 to 15 minutes. Serve.
