Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Cheese 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 the potatoes
Boil the potatoes until tender.
Let the boiled potatoes cool.
Chop the cooled potatoes into small pieces.
Make the sauce
Melt the butter in a saucepan.
Stir in the flour until smooth.
Gradually add the cold milk, stirring constantly.
Stir until the sauce thickens.
Season the sauce with salt and pepper.
Assemble and bake
Layer the chopped potatoes in a baking dish.
Pour some sauce over the potatoes.
Sprinkle grated cheese on top.
Repeat the layers until the dish is full.
Finish with cheese on the top layer.
Add a few pieces of butter on top.
Bake at 350°F (175°C) for about 45 minutes.

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 casserole and give it a soft, starchy body.
- Butter
- Enriches the sauce with fat and adds flavor and browning on top.
- All-purpose flour
- Thickens the milk into a smooth sauce that binds the layers together.
- Milk
- Forms the liquid base of the sauce, giving creaminess and moisture.
- Grated cheese
- Adds savory flavor and melts into the layers, browning on top.
The step that matters
Stir in the cold milk gradually. Adding cold milk slowly while stirring constantly lets the starch in the flour disperse evenly. Dumping it in at once can leave lumps that don't smooth out, leaving the sauce grainy.
Swap the potato
How well each one fits the dish's main ingredients (butter, flour, milk, pepper, cheese):
- Potatothe original
- Capsicumfits about as well
- Asparagusfits less well
- Chivefits less well
Fit is the average pairing score against butter, flour, milk, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
