Ingredients

Directions

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

Prepare the filling

  1. Boil the sweet potatoes until tender, then peel and pass them through a sieve.

  2. In a bowl, mix the sieved potatoes with the egg yolks, cream, sugar, butter, nutmeg, cinnamon, and salt.

Assemble and bake

  1. Gently fold in the beaten egg whites.

  2. Line a baking pan with puff pastry.

  3. Fill the pan with the sweet potato mixture.

  4. Bake at 400°F (200°C) until set.

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

What each ingredient does

Sweet potatoes
Form the bulk of the filling, giving a soft, smooth body once sieved.
Eggs
Set the custard as they cook, giving the pudding structure and firmness.
Cream
Adds richness and moisture, producing a softer, silkier texture.
Butter
Adds fat for richness and a smooth, tender mouthfeel.
Milk
Adds moisture and liquid that helps the filling set into a custard.
Granulated sugar
Adds sweetness and helps browning on the surface during baking.

The step that matters

Gently fold in the beaten egg whites. Egg whites hold air when beaten, and folding gently keeps that air in the mixture. Overmixing deflates the whites, which makes the pudding denser and less light after baking.

Swap the sweet potato

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

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

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