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 ↓
Scalloped Potatoes
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Peel and thinly slice the raw potatoes.
Assemble
Layer the potatoes in a baking dish, seasoning each layer with salt, pepper, and butter.
Continue layering until the dish is full.
Pour cream or milk over the top, then sprinkle with bread crumbs and add a small piece of butter.
Bake and serve
Bake at 350°F (175°C) for one hour and serve hot.

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 a tender, starchy body as they bake.
- Cream or milk
- Provides liquid that cooks into a creamy sauce around the potato slices.
- Butter
- Adds fat for richness and helps the top brown lightly in the oven.
- Bread crumbs
- Form a topping that adds texture and helps the surface brown.
The step that matters
Pour cream or milk over the top, then sprinkle with bread crumbs and add a small piece of butter.. The liquid needs to reach down between the layers so the potatoes cook evenly and the sauce thickens as starch releases. Adding it before the crumb topping and butter keeps the surface from drying out before the potatoes are tender.
