The juice and grated rind of one lemon, one tablespoon cornstarch, one teacup sugar, two eggs (reserving the white of one), one cup boiling water. Mix all together and cook, stirring constantly until it thickens; pour it in the crust and bake. Beat the white with three spoons sugar and spread on top; return to the oven and brown lightly. — Mrs. McKenzie.
