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 ↓
Mashed 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
Peel and chop the potatoes.
Boil the potatoes until tender, then drain.
Mash and bake
Mash the potatoes with the cream until smooth.
Transfer to a baking dish, dot with butter on top.
Bake in a 400°F (200°C) oven until browned.

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 and, once mashed, provide its soft, starchy body.
- Cream
- Adds moisture and richness, helping the mashed potatoes turn smooth and creamy.
- Butter
- Adds fat and flavour, and helps the top brown in the oven.
The step that matters
Boil the potatoes until tender, then drain. Potatoes that are undercooked stay firm and lumpy when mashed, while overcooked ones turn waterlogged. Draining well removes excess water so the mash is thick rather than watery.
Swap the potato
How well each one fits the dish's main ingredients (cream, butter):
- Potatothe original
- Onionfits about as well
- Leekfits less well
- Chivefits less well
Fit is the average pairing score against cream, butter. Candidates are from the same food group and used in at least 100 recipes.
