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.
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 butter.
Bake in a preheated oven at 400°F (200°C) for about 15 minutes, or until browned.
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 flaked fish body that forms the main substance of the dish.
- White sauce
- Binds the flaked fish together and keeps the mixture moist as it bakes.
- Breadcrumbs
- Form a crisp, browned topping during baking.
- Butter
- Adds richness and helps the breadcrumb topping brown.
- Mushroom sauce
- Adds savoury, umami depth to the white sauce.
- Anchovy essence
- Adds a salty, savoury depth that rounds out the sauce.
The step that matters
Lightly cover the top with breadcrumbs and dot with butter. Too heavy a layer of breadcrumbs can stay pale and dry, while bare or unevenly dotted sauce may not brown well. A light, even layer with butter helps the top toast and gives a golden finish.

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).
