Why it works: Bread and butter 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 ↓
Scolloped Potatoes
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Slice cold boiled potatoes quite thin.
Butter a pudding dish and layer potatoes, then add a layer of bread or cracker crumbs.
Assemble
Season each layer with coarse sea salt, black pepper, and butter.
Continue layering until the dish is filled.
Pour enough sweet milk over the layers to moisten well, adding beaten eggs if desired.
Bake and serve
Bake in a 350°F (175°C) oven for 40 to 60 minutes and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Form the bulk of the dish and set into tender layers as they absorb the milk.
- Sweet milk
- Provides moisture that softens the potatoes and forms the creamy sauce as it bakes.
- Bread or cracker crumbs
- Add a light, crisp texture to the layers and help absorb excess liquid.
- Butter
- Adds richness and fat, helping the top brown and the flavor develop.
- Eggs
- Help the milk set into a custard-like binding when added to the layers.
The step that matters
Pour enough sweet milk over the layers to moisten well. The milk must soak through all the layers so the potatoes cook evenly and the sauce sets properly. Too little liquid leaves dry, uneven layers, while the baking time and oven heat then determine how tender and cohesive the dish becomes.
Swap the potato
How well each one fits the dish's main ingredients (bread, pepper, butter, milk, egg):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Tomatofits less well
Fit is the average pairing score against bread, pepper, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
