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.

Prepare

  1. Boil the sweet potatoes until tender.

  2. Once cool, mash the sweet potatoes.

  3. Add butter, salt, pepper, and parsley to the mashed sweet potatoes and mix thoroughly.

Shape and bake

  1. Spoon the mixture into well-greased gem pans.

  2. Rough the tops with a fork and sprinkle with brown sugar.

  3. Bake in a hot oven at 400°F (200°C) for 20 minutes.

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

What each ingredient does

Sweet potatoes
Form the main body of the puffs, providing starch, moisture and natural sweetness.
Butter
Adds fat for richness and a softer, smoother texture in the mash.
Brown sugar
Sprinkled on top, it sweetens the surface and helps it caramelise and brown in the oven.

The step that matters

Rough the tops with a fork and sprinkle with brown sugar. Scoring the surface with a fork creates ridges that brown more evenly, and the sugar caramelises on them. Skipping this leaves the tops pale and flat.

Swap the sweet potato

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

  1. Carrotfits better
  2. Capsicumfits better
  3. Shallotfits better
  4. Sweet potatothe original

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