Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fish Pie with Macaroni
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Break macaroni into 1/4-inch pieces and cook in boiling salted water until tender; drain and rinse with cold water.
Butter a baking dish and arrange macaroni and fish in alternate layers; sprinkle with salt and cayenne.
Bake and serve
Pour white sauce over the layers.
Cover with buttered crumbs and brown in a hot oven at 400°F (200°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish and gives it a firm, starchy body once cooked and layered.
- Cooked fish
- Provides the main protein and flavour, layered through the macaroni.
- Medium white sauce
- Adds moisture and binds the layers so the pie does not dry out in the oven.
- Buttered crumbs
- Form a crisp, golden top through browning in the hot oven.
The step that matters
Browning the crumb topping in a hot oven. The buttered crumbs need enough heat to brown and crisp; too low and the top stays pale and soft, while the sauce beneath needs time to heat through.
“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.
