Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
White 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
Preheat your oven to 400°F (200°C).
Line your baking plates with pastry.
Make the filling
In a bowl, cream together the butter and sugar.
Add the eggs one at a time, mixing well after each addition.
Incorporate the mashed potatoes, cream, and salt into the mixture.
Stir in the rose water, brandy, nutmeg, and cinnamon.
Bake and serve
Pour the mixture into the lined plates and bake until set.
Once done, let cool, then transfer to serving plates and sift white sugar over the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to build a light, rich texture and fat content.
- Sugar
- Sweetens the filling and helps cream the butter into a smooth base.
- Eggs
- Add structure and help the filling set when baked.
- Potatoes
- Provide body and moisture to the filling.
- Cream
- Adds moisture and richness to the filling.
The step that matters
Bake until set. Baking only until the eggs have set keeps the custard-like filling tender. Overbaking causes the egg proteins to tighten too much, making the texture dry and grainy.
Swap the potato
How well each one fits the dish's main ingredients (butter, sugar, egg, cream, rose, brandy, nutmeg):
- Sweet potatofits about as well
- Arrowrootfits about as well
- Potatothe original
- Spinachfits about as well
Fit is the average pairing score against butter, sugar, egg, cream, rose, brandy, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
