Why it works: Nutmeg and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 11,917 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Sweet Potato Pudding
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
Boil the sweet potatoes until tender, then peel and pass them through a sieve.
In a bowl, mix the sieved potatoes with the egg yolks, cream, sugar, butter, nutmeg, cinnamon, and salt.
Assemble and bake
Gently fold in the beaten egg whites.
Line a baking pan with puff pastry.
Fill the pan with the sweet potato mixture.
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):
- Sweet potatothe original
- Potatofits about as well
- Arrowrootfits less well
- 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.
