Ingredients.

Tomatoes, medium sized

Boiling water

Salt

Cucumbers (or celery)

Mayonnaise dressing

Lettuce leaves Method.

Cover medium sized tomatoes with boiling water for a minute and remove the skin. Cut a thin slice from the top and take out part of the seeds and pulp. Sprinkle inside of the tomato with salt, invert, and let stand one half hour. Fill tomatoes with cucumbers (or celery) cut in small cubes and moistened with mayonnaise dressing. Arrange on lettuce leaves and garnish top with mayonnaise dressing.

Laboratory-Management

1/2 egg yolk (1 teaspoonful) and \ cup of olive oil is as small a quantity as is practicable to use in making the mayonnaise. This quantity made by groups of two works out well as the process of adding the oil drop by drop is difficult for a beginner working alone. The boiled dressing works in well as a variation of the boiled custard.
