Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Creamed 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.
Make the cream sauce
Make a cream sauce by melting butter in a saucepan, then whisk in flour until smooth.
Gradually add cream (or milk) while stirring until thickened.
Combine and bake
Combine the cream sauce with the cut potatoes, using half as much sauce as potatoes.
Transfer the mixture to a baking dish and top with buttered crumbs.
Bake in a preheated oven at 350°F (175°C) until golden.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish, giving it body and soft texture.
- Cream
- Adds richness and fat, thickening into a smooth sauce that coats the potatoes.
- Butter
- Adds fat and flavor to the sauce and helps the crumb topping brown.
- Flour
- Thickens the butter and cream into a stable sauce that holds the potatoes together.
The step that matters
Make the cream sauce smooth. Whisking flour into melted butter before adding liquid prevents lumps, and adding cream gradually while stirring lets starch gelatinize evenly into a smooth, thickened sauce.
Swap the potato
How well each one fits the dish's main ingredients (cream, butter, flour):
- Leekfits better
- Arrowrootfits about as well
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against cream, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
