Stewed Haddock

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Poach the fish

  1. Simmer the haddock in a pan of salted water for 1 hour.

  2. Place the fish on a platter.

Assemble and bake

  1. Pour drawn butter over the fish.

  2. Spread enough mashed potatoes to cover the fish nicely.

  3. Spread the egg whites over the potatoes.

  4. Bake in a 350°F (175°C) oven until light brown.

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

What each ingredient does

Haddock
Forms the main body of the dish and turns flaky as it cooks through.
Drawn butter
Adds fat and richness, keeping the fish moist during baking.
Mashed potatoes
Forms a soft layer that covers the fish and holds moisture beneath the topping.
Egg whites
Set under heat to form a light topping and brown richly in the oven.

The step that matters

Bake in a 350°F (175°C) oven until light brown. Egg whites set and brown through Maillard reactions as they heat. Pulling the dish too early leaves the topping pale and wet, while baking too long can dry the fish and toughen the topping.

Swap the potato

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

  1. Potatothe original
  2. Chivefits about as well
  3. Asparagusfits less well
  4. Spinachfits less well

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