Why it works: Butter and cream 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

  1. Peel and boil the potatoes.

  2. Mash the potatoes in a deep dish using a potato masher.

  3. Add coarse sea salt, a piece of butter, and ½ cup of cream or milk.

  4. Beat the mixture lightly with a spoon.

Bake and serve

  1. Transfer to a serving dish or tin plates.

  2. Brush the tops with egg and bake in a 400°F (200°C) oven for 10 to 15 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Provide the starchy body that the mash holds together and becomes fluffy.
Butter
Adds fat for richness and a smooth, silky mouthfeel.
Cream or milk
Adds moisture and makes the mash creamy and easy to spread.
Egg
Promotes browning on the surface during baking.

The step that matters

Beat the mixture lightly. Potato starch swells and releases sticky starch when worked vigorously, so overbeating turns mashed potatoes gluey. A light touch keeps them fluffy.

Swap the potato

How well each one fits the dish's main ingredients (butter, cream, egg):

  1. Leekfits about as well
  2. Potatothe original
  3. Asparagusfits about as well
  4. Chivefits about as well

Fit is the average pairing score against butter, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
