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 ↓
Escaloped Potatoes
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Cut raw potatoes into thin slices.
Layer the slices in a buttered pudding dish.
Sprinkle each layer with pepper, coarse sea salt, and bits of butter.
Fill the dish three-fourths full.
Bake
Cover with milk and bake at 300°F (150°C) for two hours.
Optionally, add bread or cracker crumbs on top before baking.
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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw potatoes
- Form the bulk of the dish and soften into tender layers as they bake.
- Butter
- Adds richness and fat that carries flavour through the layers.
- Milk
- Provides liquid that cooks the potatoes gently and forms the creamy sauce.
The step that matters
Covering with milk and baking slowly. Low, slow heat lets the potato starch soften fully and the milk thicken without curdling or scorching. Cooking too hot can dry the top and leave the potatoes firm inside.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, milk, bread):
- Capsicumfits about as well
- Potatothe original
- Tomatofits about as well
- Asparagusfits less well
Fit is the average pairing score against butter, pepper, milk, bread. Candidates are from the same food group and used in at least 100 recipes.
