Beat the eggs and mix with the milk.
Melt the butter and pour it over the macaroni.

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 its main structure.
- Eggs
- Set when baked, binding the custard and holding the pasta together.
- Milk
- Combines with the eggs to form a moist, creamy custard.
- Butter
- Adds richness and fat, coating the pasta for a softer texture.
The step that matters
Pour the egg and milk mixture over everything. The egg and milk custard must reach every layer so it can set evenly on baking. Egg proteins coagulate with heat, so uneven distribution can leave wet pockets or a grainy, unset texture.
“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.
