Ingredients

Directions

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

Prepare

  1. Break the fish into flakes.

  2. Mash the potatoes with a little milk and salt.

Assemble and bake

  1. Season the fish and place it in a pie dish with parsley, mace, and melted butter.

  2. Pile the mashed potatoes on top, mark with a fork, and bake at 400°F (200°C) until brown.

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

What each ingredient does

Cooked fish
Forms the main body of the filling, giving it flaky texture.
Cooked potatoes
Make the mashed topping that sets and browns in the oven.
Butter
Adds fat and richness, and helps keep the filling moist.
Milk
Moistens the mashed potatoes so they spread smoothly over the fish.
Mace
Adds a warm, aromatic flavour to the fish filling.

The step that matters

Baking the potato topping until brown. Marking the mashed potatoes with a fork creates ridges that brown well, and the surface needs enough time in the oven toColour. Stopping too early leaves the topping pale and the filling underheated, while baking too long can dry the potatoes out.

Swap the mace

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

  1. Thymefits better
  2. Marjoramfits better
  3. Dillfits better
  4. Macethe original

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