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 ↓
Delicatessen Potatoes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the potatoes
Crumble the warm baked potatoes after removing them from their skins.
Make the cream sauce
In a saucepan, melt 3 tablespoons of butter and whisk in 4 tablespoons of flour to make a roux.
Gradually add milk to the roux until a thick cream sauce forms. Season with salt and pepper.
Assemble and bake
In a baking dish, layer half of the crumbled potatoes, followed by half of the cream sauce. Repeat with the remaining potatoes and sauce.
Bake at 400°F (200°C) until the top is browned.
Top and serve
In a separate saucepan, heat 2 tablespoons of melted butter and mix in the toasted bread crumbs.
Just before serving, sprinkle the buttered bread crumbs over the scalloped potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baked potatoes
- Form the bulk of the dish, providing starchy body that soaks up the sauce.
- Flour
- Thickens the butter and milk into a smooth, stable cream sauce.
- Butter
- Adds richness and carries flavor, and helps the flour form a roux.
- Milk
- Forms the liquid base of the cream sauce, giving it a creamy texture.
- Toasted bread crumbs
- Add a crisp, golden topping when coated in butter and baked.
The step that matters
Adding milk to the roux. Adding milk gradually while whisking keeps the flour smooth and lump-free, so the sauce thickens evenly instead of clumping.
Swap the potato
How well each one fits the dish's main ingredients (flour, butter, milk, pepper, bread):

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