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 ↓

Ingredients
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.
Make the sauce
Mix milk, flour, and butter in a saucepan until smooth.
Season the sauce with salt and pepper.
Assemble and bake
Layer sauce in the bottom of a baking dish.
Add a layer of thinly sliced boiled potatoes.
Repeat the layers, finishing with sauce on top.
Sprinkle with fine bread crumbs.
Bake in a hot oven at 400°F (200°C) until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the white sauce that coats and moistens the potatoes.
- Flour
- Thickens the milk into a smooth sauce that holds the layers together.
- Butter
- Adds richness and fat to the sauce, helping it taste full and brown lightly.
- Boiled potatoes
- Provide the starchy body of the dish, softening as they bake in the sauce.
- Fine bread crumbs
- Form a crisp, browned topping on the surface during baking.
The step that matters
Make the sauce smooth before layering. Flour lumps in the sauce will not dissolve in the oven, so the flour must be fully mixed with the milk and butter. Stirring the sauce until smooth lets the starch thicken evenly, so the layers bind rather than separate into wet and dry pockets.
Swap the potato
How well each one fits the dish's main ingredients (milk, flour, butter, pepper, bread):

Fit is the average pairing score against milk, flour, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
