I don't personally know any contributors to Twickenham Receipts and Sketches (The Twickenham Historical Preservation District Association, Inc., Huntsville, AL, 1978), but I have a feeling Mrs. Howard (Betty) O'Meara was pretty laid-back.
How do you prepare the pie before baking? Just follow the title and "Mix Any Old Way." Bonus points if you noticed this one doesn't even require a crust. Pretty chill, Mrs. O.
