How to Make It
Arrange the tomatoes on a large platter. In a small bowl, whisk the white wine and balsamic vinegars with the sugar and paprika. Slowly whisk in the olive oil and season with salt and pepper. Stir in the scallions and half of the basil. Pour the dressing over the tomatoes and let stand at room temperature for 1 hour. Sprinkle the remaining basil over the tomatoes and serve.
