Why it works: Butter and onion are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 42,912 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Baked 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
Blanch the macaroni in boiling water and drain.
Make the sauce
Heat the butter in a pot with finely minced onion until tender but not brown.
Add the cooked macaroni and moisten with onion sauce or cream.
Mix carefully to avoid breaking the macaroni and simmer for a few minutes.
Bake
Transfer the mixture to a buttered baking dish, adding more sauce if needed.
Sprinkle with breadcrumbs and drizzle with oiled butter.
Bake at 400°F (200°C) for 10 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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, chewy structure once baked.
- Butter
- Adds richness and moisture, and helps the crumbs brown when drizzled on top.
- Onion sauce or cream
- Moistens the pasta and makes the mixture creamy rather than dry.
- Breadcrumbs
- Form a crisp, golden crust on the surface during baking.
The step that matters
Mix carefully. Stirring too hard breaks the macaroni tubes and releases starch, making the texture mushy instead of tender and intact.
