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.

Prepare the toast

  1. Cut stale bread into thin strips or squares.

  2. Butter the bread and place it in a 400°F (200°C) oven until lightly colored.

Make the sardine topping

  1. In a bowl, mix skinned and finely picked sardines with butter until smooth.

  2. Season the mixture with lemon juice, a dash of paprika, and a hint of French mustard.

Assemble

  1. Spread the sardine mixture on the toasted bread.

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

What each ingredient does

Stale bread
Dry, sturdy base that crisps in the oven and holds the topping without going soggy.
Butter
Adds fat and richness, helps the bread brown and makes the sardine mixture smooth and spreadable.
Sardines
Provide the main savory flavour and the rich, creamy body of the topping once mashed with butter.
Lemon juice
Adds acidity that brightens the oily flavour of the sardines.
French mustard
Adds sharp, pungent notes that balance the richness of the fish and butter.

The step that matters

Toasting the bread until lightly colored. Toast that is pale and underbaked will soften under the moist sardine spread, while over-browned bread turns bitter. Stopping at light color keeps the base crisp and the flavour clean.

Swap the mustard

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

  1. Shallotfits better
  2. Asparagusfits better
  3. Leekfits better
  4. Mustardthe original

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