Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Fish Pie

Oven, in the book's wordsA quick oven

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. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

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

  2. Break the fish into flakes.

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

Assemble and bake

  1. Season the fish with salt, pepper, mace, and parsley, then place it in a pie dish.

  2. Drizzle melted butter over the fish.

  3. Spread the mashed potatoes on top and mark with a fork.

  4. Bake until brown, about 20-30 minutes.

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

What each ingredient does

Cooked fish
Forms the filling and provides the main body of the pie.
Butter
Adds richness and moisture to the fish and helps the topping brown.
Cooked potatoes
Form the mashed topping that becomes golden and crisp in the oven.
Mace
Adds a warm, aromatic spice flavour to the fish.

The step that matters

Spread the mashed potatoes on top and mark with a fork. The potato layer should seal over the fish so it stays moist underneath. Marking the surface with a fork creates ridges that brown more deeply in the oven.

Swap the mace

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

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

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