The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Drain and mix with butter, cheese, and milk.
Transfer to a baking dish and top with breadcrumbs.
Season with salt and pepper.
Bake and serve
Bake at 400°F (200°C) until golden and bubbly.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Provides the starchy body that holds the sauce and gives the gratin its structure.
- Cheese
- Melts into the sauce and browns on top, adding richness and savory flavor.
- Butter
- Adds fat for silky texture and helps the topping brown evenly.
- Milk
- Forms the liquid base that coats the pasta and turns creamy as it heats.
- Breadcrumbs
- Form a crisp, golden crust on top that contrasts with the creamy interior.
The step that matters
Cook the macaroni until al dente. Pasta cooked only to al dente keeps its firmness while baking. Overcooked pasta absorbs more sauce and turns soft and mushy in the oven.
