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 ↓
Mashed Potatoes Wttb Cheese Sauce
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.
Make the potatoes
Boil the potatoes until tender, then mash them.
Add 1 tablespoon of butter, salt, pepper, and ½ cup of milk to the mashed potatoes.
Form the mixture into conical shapes using an ice cream scoop or small cups rinsed with cold water.
Place the shaped potatoes on a platter in a 400°F (200°C) oven, leaving the door partly open to prevent drying.
Make the cheese sauce
In a double boiler, melt 1 tablespoon of butter for the cheese sauce.
Add 1 tablespoon of flour to the melted butter and blend thoroughly.
Stir in 1 cup of hot milk and season with a dash of paprika and salt to taste.
Once smooth, add 1 cup of cheese and stir until melted.
Keep the cheese sauce warm in the double boiler until ready to serve.
Serve
Serve the potatoes on a hot platter with the cheese sauce in a gravy boat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Starch that mashes into a soft, smooth base that holds its shape when formed.
- Butter
- Adds fat and richness, carrying flavor and a smooth mouthfeel to both the potatoes and the sauce.
- Milk
- Adds moisture and loosens the mashed potatoes, and forms the liquid base of the cheese sauce.
- Flour
- Thickens the melted butter and hot milk into a smooth, cohesive cheese sauce.
- Cheese
- Melts into the sauce, adding savory flavor and a creamy, stretchy body.
The step that matters
Stir in the hot milk gradually and keep the sauce warm. Flour must be cooked smoothly into the butter before liquid is added, or lumps form. Keeping the sauce gently warm in a double boiler prevents scorching and skinning while the starch stays thick and the cheese stays melted.
