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 the macaroni
Break macaroni into small pieces.
Cook the macaroni in boiling salted water until tender.
Drain the macaroni, then rinse the macaroni with cold water.
Assemble the pie
Butter a baking dish.
Arrange macaroni and fish in alternate layers.
Sprinkle the layers with salt and cayenne pepper.
Pour white sauce over the layers.
Cover the pie with buttered crumbs.
Bake
Brown the pie in a hot oven at 400°F (200°C).

Sauce and pepper barely smell alike, yet cooks put them together in 15,303 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Provides the starchy body that holds the pie together as it cooks.
- Fish
- Supplies the main flavour and protein, layered through the macaroni.
- White sauce
- Adds moisture and a creamy binding that keeps the layers from drying out.
- Buttered crumbs
- Form a crisp, golden topping through browning in the oven.
- Lemon juice
- Adds acidity that brightens the flavour of the fish and sauce.
The step that matters
Rinse the macaroni after draining. Rinsing with cold water stops the cooking so the pasta does not keep softening and turn mushy while it bakes in the pie.
