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
Remove skin and bones from the cod and break it into large flakes.
Prepare the white sauce as directed, then stir in the mushroom sauce, anchovy essence, mustard, salt, and pepper to taste.
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 and dot with a few pieces of butter.
Bake in a 400°F (200°C) oven until well browned, about 15 minutes.
Serve directly from the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Provides the flaky main protein that forms the body of the dish.
- White sauce
- Binds the fish and keeps the mixture moist during baking.
- Breadcrumbs
- Form a crisp, browned topping when baked.
- Butter
- Adds richness and helps the breadcrumb topping brown.
- Mixed mustard
- Adds sharp flavor that balances the richness of the sauce.
The step that matters
Bake until well browned. The sauce and fish must heat through while the breadcrumbs and butter brown. Browning relies on dry surface heat, so the topping can scorch before the centre is hot if the oven runs too hot or the dish sits too close to the heat.

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).
