Why it works: Bread and butter match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 27,145 recipes mention both. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Fry the bread fingers in clarified butter until golden, then drain them.
Place one sardine on each bread finger and arrange them on a round dish in a lattice pattern.
Make the sauce
In a saucepan, combine the beaten egg yolks, butter, cream, essence of anchovy, chopped onions, salt, pepper, and cayenne.
Stir the mixture over low heat until it thickens.
Bake and serve
Heat the dish in a 400 °F (200 °C) oven for a few minutes until hot.
Pour the sauce over the sardines, sprinkle with meat glaze, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Provide the main fish flavour and the savoury centre of the dish.
- Egg yolks
- Thicken the sauce as they set gently over low heat, giving it a smooth, rich body.
- Butter
- Adds richness and a silky mouthfeel to the sauce.
- Cream
- Adds moisture and softness, helping the sauce stay smooth rather than grainy.
- Bread
- Forms a crisp, golden base that holds the sardines above the sauce.
The step that matters
Thickening the sauce over low heat. Egg yolks set at moderate temperatures, and high heat or long stirring can scramble them into lumps. Gentle, constant stirring keeps the sauce smooth and pourable.

Fit is the average pairing score against bread, butter, egg, cream, anchovy, pepper, meat. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
