First put the oil into a small bowl. Then add gradually the salt and pepper until all are thoroughly mixed. Then add gradually the vinegar, stirring continually for about a minute. It is now ready to pour over the Salad, and remember that it must be mixed thoroughly. The proportion of vinegar varies according to the Salad to be dressed. Lettuce Salad requires but little; Tomato Salad, Corn Salad or Doucette require more. Serve this Dressing with Lettuce, Tomato, Onion, Cucumber and other Vegetable and Green Salads.
