Ingredients

Directions

The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Soften the cold mashed potatoes in a saucepan over low heat with a little milk and butter.

  2. Remove from heat and mix in the chopped meat and beaten egg.

Bake

  1. Transfer the mixture to a buttered pie plate and mound it up.

  2. Sprinkle a handful of dry bread crumbs on top.

  3. Bake in a 400°F (200°C) oven for about 15 minutes, or until deep brown.

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

What each ingredient does

Mashed potatoes
Form the bulk of the pie and set into a soft, sliceable base when baked.
Beaten egg
Binds the potatoes and meat together so the filling holds its shape.
Chopped meat
Adds savory flavor and substance to the potato base.
Butter
Adds richness and flavor, and helps the potatoes soften and brown.
Dry bread crumbs
Form a crisp, browned topping on the mounded filling.

The step that matters

Baking until deep brown. Browning comes from surface heat and dry crumbs; pulling the pie too early leaves the topping pale and the centre under-set, while over-baking can dry it out.

Swap the potato

How well each one fits the dish's main ingredients (milk, butter, meat, egg, bread):

  2. Asparagusfits about as well
  3. Leekfits less well
  4. Capsicumfits less well

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