3 slices bacon
1 egg, well beaten
1 1/2 tbsp. flour
1 c. milk
1/4 c. vinegar
1/4 c. sugar
1/2 tsp. salt
1 qt. salad greens

Chop bacon and fry until crisp; remove bacon and add to greens. Add all other ingredients to beaten egg and pour into the hot bacon fat. Cook until thickened. Pour at once over salad greens, such as lettuce, endive, dandelion, or spinach. A little chopped onion could be added to the greens, if desired.
