Salad Dressing

Boil 1 cup water and 1/4 cup lemon juice; rub to paste 4 tablespoonfuls (level) of flour and 2 tablespoonfuls of oil (olive or mazola.) Pour boiling water and lemon juice over the paste gradually. When well blended place over fire and boil slowly for 5 minutes. Pour this boiled mixture over 1 well-beaten egg, stirring or beating with egg beater all the time. Chill; then add 1 cup oil, 1/4 at a time, beating all the time. When smooth add 1 teaspoonful salt and good pinch of cayenne pepper and pinch of mustard, if desired, mixed with tablespoonful more of oil.
