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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Boil macaroni in salted water until al dente, about 8-10 minutes.
Drain and set aside.
In a saucepan, melt butter and stir in flour to make a roux.
Gradually add milk, stirring until thickened.
Add cheese, salt, and pepper to the sauce, mixing until melted.
Combine macaroni with cheese sauce and pour into a baking dish.
Top with bread crumbs and bake at 350°F (175°C) until golden brown, about 20 minutes.

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.
