Review the facts on boiling vegetables learned in the previous lesson.
Let the pupils put water on to boil and prepare a vegetable for cooking.
If experiments are to be made, they can be performed while the vegetable
is cooking. If the experiments have been made previously, they can be
reviewed in discussion at this time. Prepare a white sauce by
demonstration, using the method which seems most practical. Have the
vegetables drained, dried, and added to the white sauce. When
well-heated, serve.
