"These flavorful baked onions are a great accompaniment to grilled meat," writes field editor Karen Owen of Rising Sun, Indiana. "They aren't crisp like the deep-fried 'blooming onions' served in restaurants, but we think they are equally delicious."

  • 4 large sweet onions, peeled
  • 1/4 cup red wine vinegar
