Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Potatoes, with Cheese Sauce
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sauce
In a saucepan, stir the pepper, salt, nutmeg, beaten eggs, and half the cheese into the hot drawn butter.
Heat while stirring constantly until it thickens.
Assemble and bake
Layer mashed potatoes in a flat dish, shaping them to fit.
Cover with the cheese sauce.
Repeat with another layer of potatoes and sauce until you form a mound on top.
Coat the top with sauce, then sprinkle with the remaining cheese and cracker dust.
Arrange the fried bread triangles around the base.
Bake in a 400°F (200°C) oven until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs thicken the hot butter sauce as they set, binding it into a spoonable custard.
- Potatoes
- Mashed potatoes form the bulk of the casserole, giving a soft, moist body under the sauce.
- Drawn butter
- Hot butter carries the flavour and richness and helps the sauce stay smooth and glossy.
- Cheese
- Dry grated cheese adds savoury flavour and helps the topping brown in the oven.
The step that matters
Heating the egg sauce. Stirring constantly keeps the beaten eggs from scrambling in the hot butter. Gentle, steady heat lets them thicken smoothly into a sauce rather than curdling into lumps.
Swap the nutmeg
How well each one fits the dish's main ingredients (potato, milk, butter, cheese, egg, pepper, bread):
- Parsleyfits about as well
- Nutmegthe original
- Thymefits about as well
- Cinnamonfits less well
Fit is the average pairing score against potato, milk, butter, cheese, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
