Mashed Potatoes

Ingredients

Directions

  1. Boil the potatoes until tender, then drain the water and remove the cover to let the steam escape.

  2. Mash the potatoes well and add salt, white pepper, and enough hot milk or cream to make them light and creamy.

  3. Incorporate the butter and beat the mixture again.

  4. Transfer to a hot vegetable dish without smoothing them down to avoid making them hard and soggy.

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

What each ingredient does

Potatoes
Provide the starch that gives mashed potatoes their bulk and fluffy body.
Butter
Adds fat for richness and a smoother, silkier mouthfeel.
Milk or cream
Adds moisture so the mash becomes light and creamy rather than stiff.

The step that matters

Transfer without smoothing the surface. Overworking or smoothing the mash makes it dense, gluey and soggy as it sits, so it should be left loosely piled in the hot dish.

Swap the white pepper

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Parsleyfits better
  4. White pepperthe original

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