Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Macaroni— No. 3
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
Boil the macaroni until perfectly tender.
In a saucepan, boil the cream and butter together.
Stir in the eggs until the mixture thickens.
Add the mustard, salt, and cayenne pepper.
Assemble and bake
In a heatproof dish, layer macaroni, sauce, and cheese until filled.
Serve very hot or bake in a 400°F (200°C) oven for 20 minutes, sprinkling cheese and small pieces of butter on top.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk and firm, starchy body of the casserole.
- Butter
- Adds richness and fat that carries flavor and gives a smooth mouthfeel.
- Cream
- Makes the sauce rich and silky, adding moisture and body.
- Eggs
- Thicken the cream sauce as they set with gentle heat, giving it structure.
- Parmesan cheese
- Adds salty, savory flavor and browns on top during baking.
The step that matters
Stir in the eggs until the mixture thickens. Eggs thicken when heated gently but can scramble if the sauce boils too hard. Keep the heat low and stir constantly so the custard-like sauce becomes smooth rather than curdled.
Swap the mustard
How well each one fits the dish's main ingredients (butter, cream, parmesan cheese, pepper, egg):
