At some previous period the teacher should have discussed with the
pupils the use of potatoes and learned from them the different ways in
which they cook them in their homes. She should determine upon some
recipes for the lesson that will increase the variety of ways in which
potatoes may be served and that will improve the methods used in the
homes.
Each pupil should be asked to bring one or two potatoes for the lesson.
The best methods of cooking and the means of securing variety should be
emphasized.
