Why it works: Sauce and cheese are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 1,987 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Preheat the oven to 400°F (200°C).
Cover the bottom of a baking dish with a layer of cooked macaroni.
Add a layer of hard-cooked eggs, sliced thin.
Pour white sauce over the layers.
Top with buttered crumbs or grated cheese.
Bake until browned.
