Why it works: Beef and pepper are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,971 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Macaroni Au Gratin
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
Preheat the oven to 350°F (175°C).
Put macaroni in a fireproof brown earthenware pot and cover with beef broth.
Bake
Bake for about 2 hours, stirring occasionally and adding more stock as needed.
Once done, add hot milk, grated cheese, salt, and pepper.
Finish and serve
Transfer to an oval dish, sprinkle with bread crumbs and additional cheese.
Brown under a broiler and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the body of the dish, absorbing broth and milk to become tender and substantial.
- Beef broth
- Cooks the pasta and adds savory flavor and moisture as it is absorbed.
- Hot milk
- Adds moisture and creaminess, helping form a smooth sauce around the pasta.
- Grated parmesan cheese or gruyere cheese
- Melts into the sauce for richness and saltiness, and browns under the broiler.
- Fine white bread crumbs
- Forms a crisp topping that browns under the broiler for texture contrast.
The step that matters
Brown under a broiler. Broilers brown quickly, so the crumb and cheese topping can burn before it is golden. Watch closely and remove the dish as soon as the top is evenly colored.
“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.
