Directions:

In a small bowl, beat egg whites until stiff peaks form; set aside.

In another mixing bowl, combine the sugar, flour, egg yolks, lemon juice, lemon peel, butter and salt. Beat in milk just until blended. Fold in egg whites. Pour into an ungreased, shallow 1-1/2 qt. baking dish. Place the dish in a larger baking pan. Pour boiling water into larger pan to a depth of 1-inch.

Bake at 350 degrees for 45 minutes or until lightly browned. Refrigerate leftovers.
