Mashed Sweet Potatoes

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the mash

  1. Scoop out the sweet potatoes into a bowl.

  2. Add salt, pepper, cream, and butter.

  3. Mash until creamy.

Bake

  1. Transfer to a buttered dish.

  2. Bake in a 400°F (200°C) oven until brown.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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, creamy texture of the mash.
Cream
Adds moisture and richness, making the mash smooth and silky.
Butter
Adds fat for richness and flavor, and helps the top brown in the oven.

The step that matters

Bake until brown. The top needs enough oven time to brown through the Maillard reaction, which builds savory flavor. Stopping early leaves it pale and under-flavored, while over-baking can dry the surface.

Swap the sweet potato

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

  1. Potatofits better
  2. Spinachfits better
  3. Capsicumfits better
  4. Sweet potatothe original

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