Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Eggs and Macaroni
Ingredients
Directions
Prepare
Break macaroni into 1-inch pieces and cook in boiling water until tender.
Boil the yolks of the eggs until mealy.
Layer and make the sauce
Drain the macaroni and layer it loosely in an earthen pudding dish.
Slice the cooked egg yolks and spread a layer over the macaroni.
Continue layering with macaroni and egg, finishing with a top layer of macaroni.
In a saucepan, heat the milk to boiling, add salt and flour mixed with cold milk, and cook until thickened.
Pour the cream sauce over the layered macaroni and eggs.
Bake and serve
Bake until the top is set and serve.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Forms the bulk and structure of the dish, holding the layers together.
- Egg yolks
- Enrich the dish and help it set firmly when baked, adding richness and body.
- Milk
- Forms the liquid base of the cream sauce, providing moisture and a creamy texture.
- Flour
- Thickens the milk into a cream sauce that binds the dish together.
The step that matters
Thickening the cream sauce. Flour must be smoothed in cold milk before adding to boiling milk, otherwise it clumps. Cooking until thickened lets the starch swell fully so the sauce coats the layers evenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
