Why it works: Pepper and nutmeg match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 13,015 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Roman Pie
Ingredients
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
Preheat the oven to 400°F (200°C).
Butter a large pie dish and line it with macaroni.
Layer the filling
Cut the cooked cold meat into small pieces and layer it in the pie dish.
Pour a little white or brown sauce over each layer and season with salt, pepper, and grated nutmeg.
Once the dish is full, cover it with a layer of rich béchamel sauce.
Top and bake
Sprinkle grated parmesan cheese on top and cover neatly with boiled macaroni.
Drizzle melted butter over the macaroni and add more grated cheese.
Bake for about 30 minutes until the surface is nicely browned and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the base and top crust, giving the pie its structure and body.
- Cooked cold meat
- Provides the main savoury filling, adding flavour and substance to each layer.
- White or brown sauce
- Adds moisture between layers so the filling stays juicy as it bakes.
- Rich béchamel sauce
- Its fat and starch create a creamy layer that helps the top brown when baked.
- Grated parmesan cheese
- Melts and browns on the surface, adding savoury flavour and a golden crust.
- Melted butter
- Adds fat that promotes browning and richness on the macaroni topping.
The step that matters
Covering the top layer of macaroni and cheese. Brushing or drizzling melted butter over the macaroni before baking encourages even browning, since fat promotes the Maillard reaction on the surface. Neat coverage keeps the sauce sealed in the filling.
Swap the nutmeg
How well each one fits the dish's main ingredients (meat, sauce, pepper, parmesan cheese, butter):
- Parsleyfits better
- Capersfits better
- Thymefits better
- Nutmegthe original
Fit is the average pairing score against meat, sauce, pepper, parmesan cheese, butter. Candidates are from the same food group and used in at least 100 recipes.
