Potato Pie Crust
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the crust
Boil the dry mealy potatoes until tender.
Sift the potatoes through a colander.
Mix the sifted potatoes thoroughly with half of their quantity.
Add boiling water equal to about one-fourth of the mixture's bulk.
Roll the mixture thin.
Bake
Bake in a moderate oven at 350°F (175°C).

What each ingredient does
- Dry mealy potatoes
- Provide the starch and body that form the crust's structure once cooked and mashed.
- Boiling water
- Adds moisture and heat to bind the sifted potato into a workable, pliable dough.
The step that matters
Adding the boiling water. Too much water makes the mixture sticky and hard to roll thin, while too little leaves it crumbly. Starch in the potato absorbs the hot water and swells, so the dough holds together when rolled.
