Potato Pie

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the filling

  1. Slice the potatoes and onion.

  2. Stew the potatoes and onion with water until nearly done.

  3. Transfer the mixture to a pie dish and season with herbs, pepper, and salt.

  4. Add the soaked tapioca and butter, mixing well.

Bake

  1. Cover with a short wheatmeal crust made by mixing wheatmeal with milk.

  2. Bake at 400°F (200°C) for 1 hour.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Form the bulk of the pie, softening during stewing and turning starchy and filling.
Tapioca
Thickens the juices from the stewed vegetables so the filling sets rather than running.
Butter
Adds richness and moisture to the filling and helps the top brown in the oven.
Wheatmeal
Forms the short crust that encloses the filling as it bakes.

The step that matters

Stew the potatoes and onion until nearly done. The vegetables finish cooking in the oven, so if they are underdone they stay firm, and if overdone they turn mushy. Stopping at nearly done keeps slices intact and the filling tender.

Swap the onion

How well each one fits the dish's main ingredients (potato, pepper, butter, milk):

  1. Capsicumfits better
  2. Asparagusfits about as well
  3. Tomatofits about as well
  4. Onionthe original

Fit is the average pairing score against potato, pepper, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
