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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the components
Boil macaroni in a saucepan until tender.
Boil the eggs in a separate saucepan until hard-cooked.
Remove shells from the eggs and slice them thinly.
Assemble and bake
In a pudding dish, layer macaroni and egg slices alternately, finishing with macaroni on top.
Sprinkle the layered dish with coarse sea salt.
Heat the milk to boiling.
Thicken the milk with flour mixed in a little cold milk.
Pour the thickened milk over the layered macaroni and eggs.
Place the dish in a 350°F (175°C) oven to brown.

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 of the casserole and holds the layers together when cooked until tender.
- Eggs
- Add richness and body, setting firm when hard-cooked and layered through the dish.
- Milk
- Provides liquid that, once thickened and baked, forms a creamy custard-like sauce.
- Flour
- Thickens the hot milk so the sauce coats the layers rather than running off.
The step that matters
Thickening the milk with flour. Flour must be mixed into cold milk first so it disperses evenly; added directly to hot milk it clumps, leaving lumps in the sauce.
“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.
