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 the filling

Chop the meat finely with the onion and any cooked vegetables you have.
Add pepper, salt, and gravy or stock to the mixture.

Bake

Arrange the mixture in a baking dish and top with mashed potatoes to form a crust.
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

Meat: Forms the savoury body of the filling.
Mashed potatoes: Form the top crust, which browns in the oven and holds the filling in.
Gravy or stock: Adds moisture so the filling stays juicy rather than dry while baking.
Onion: Adds savoury depth and aroma to the filling.
