Why it works: Onion and butter 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.
Make the macaroni base
Blanch the macaroni according to previous directions.
Heat the butter in an earthenware stewpan with the minced onion; cook until tender but not brown.
Add the cooked macaroni and moisten with the onion sauce or cream. Mix carefully to avoid breaking the macaroni.
Simmer for a few minutes, then pile the mixture neatly in a buttered baking dish.
Bake
Pour over a little more sauce if needed, sprinkle with breadcrumbs, and drizzle with oiled butter.
Bake in a hot oven at 400°F (200°C) for ten minutes.

What each ingredient does
- Macaroni
- Forms the bulk of the dish and gives it its chewy, substantial body.
- Onion sauce or cream
- Moistens the pasta and keeps the mixture creamy rather than dry in the oven.
- Butter
- Adds richness and helps the onion soften gently and carry flavour through the dish.
- Small onion
- Adds savoury aroma and flavour once cooked until tender.
- Breadcrumbs
- Form a crisp, golden topping through browning in the hot oven.
The step that matters
Cook the onion until tender but not brown. Gentle cooking softens the onion and sweetens its flavour without bitterness. Browning would turn it harsh and could spoil the mild, delicate taste of the sauce.
