Why it works: Sauce and anchovy match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 2,048 recipes mention both. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
The recipe
Ingredients
Contains: 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 the fish
Remove skin and bones from the cod.
Break the cod into large flakes.
Make the sauce
Prepare the white sauce as directed.
Stir in the mushroom sauce, anchovy essence, mustard, salt, and pepper.
Add the cod to the sauce and mix well.
Bake and serve
Transfer the mixture to a well-buttered baking dish.
Lightly cover the top with breadcrumbs.
Dot with butter.
Bake in a preheated oven at 400°F (200°C) for about 15 minutes, until browned.
Serve directly from the baking dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Provides the main body of the dish as flaked, cooked fish folded through the sauce.
- White sauce
- Carries the fish and keeps the baked dish moist and creamy rather than dry.
- Breadcrumbs
- Form a crisp, browned topping during baking.
- Butter
- Adds richness and helps the breadcrumb topping brown.
- Anchovy essence
- Adds a savoury, salty depth to the sauce.
The step that matters
Bake until browned. The cod is already cooked, so baking mainly heats it through and browns the topping. Overbaking can dry the sauce and toughen the fish, so watch for a golden top.

Fit is the average pairing score against sauce, mushroom, anchovy, butter, pepper. 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).
