Cottage 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

  1. Preheat the oven to 400°F (200°C).

Assemble

  1. Spread the minced cold meat in a pie dish, about 1½ inches deep.

  2. Cover the meat with gravy, and season with salt and pepper.

  3. Top with a thick layer of mashed potatoes and score the surface in a diamond pattern with a knife.

Bake

  1. Bake until the top is crisp and brown.

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

What each ingredient does

Minced cold meat
Forms the savory base of the pie filling.
Gravy
Adds moisture so the meat stays juicy while baking.
Mashed potatoes
Forms a topping that crisps and browns in the oven.

The step that matters

Topping the meat with mashed potatoes. The layer should be thick enough to protect the filling from drying out while the top crisps. Scoring the surface creates ridges and edges that brown more evenly.

Swap the potato

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

  1. Capsicumfits better
  2. Mustardfits about as well
  3. Carrotfits about as well
  4. Potatothe original

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