Mashed Sweet 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 the potatoes

  1. Steam the sweet potatoes over boiling water until soft.

  2. Remove the skin and mash the potatoes until perfectly smooth.

  3. Mix in the butter, cream, sugar, and nutmeg.

Shape and bake

  1. Transfer the mixture to a baking dish.

  2. Form the mixture into a pyramid.

  3. Spread melted butter or beaten egg over the top.

  4. 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

Sweet potatoes
Provide the main body and starchy, soft texture of the dish.
Butter
Adds richness and fat, giving a smooth mouthfeel and helping the top brown.
Cream
Adds moisture and silkiness, keeping the mash smooth and spreadable.
Sugar
Adds sweetness and helps the top take on color as it bakes.
Beaten egg
Coats the top to promote a glossy, browned surface, if used instead of butter.

The step that matters

Mash until perfectly smooth. Any lumps left in the cooked potato stay lumpy after baking, because heat sets the starch and does not smooth the texture. Thorough mashing while the potatoes are still hot gives an even, silky result.

Swap the sweet potato

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

  1. Sweet potatothe original
  2. Leekfits about as well
  3. Potatofits about as well
  4. Arrowrootfits about as well

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