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 ↓
Escalloped 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
Wash, peel, and slice the potatoes very thinly to cover the bottom of a baking dish.
Layer and season
Sprinkle salt, pepper, dots of butter, and flour over the first layer of potatoes.
Add another layer of potatoes and repeat the seasoning.
Once all potatoes are layered, sprinkle buttered crumbs on top.
Add milk to nearly cover the potatoes.
Bake
Bake at 350°F (175°C) for about one hour, or until tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the dish and become tender and soft as they bake.
- All-purpose flour
- Thickens the milk into a creamy sauce that binds the layers together.
- Milk
- Cooks around the potatoes to create a creamy, sauce-like base.
- Butter
- Adds richness and fat that carries flavor and helps the top brown.
The step that matters
Layering the potatoes thinly and evenly. Thin, even slices cook through at the same rate, so the potatoes become tender within the baking time. Thick or uneven slices can stay firm in the middle while the top overbrowns.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, flour, bread, milk):

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