Why it works: Potato and butter are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Potato Pudding
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Rub the boiled potatoes through a sieve.
Mix the potatoes with the butter until well combined.
Add the egg yolks and sugar, and mix thoroughly.
Make a plain pastry border and place it in a baking dish.
Bake
Fill the dish with the potato mixture.
Beat the egg whites until stiff and spread them on top.
Bake at 350°F (175°C) for one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled potatoes
- Provide the bulk and soft, smooth body of the pudding.
- Butter
- Adds richness and a tender, moist texture.
- Egg yolks
- Enrich the mixture and help it set when baked.
- Egg whites
- Beaten until stiff, they create a light topping that puffs and browns in the oven.
The step that matters
Beat the egg whites until stiff. Egg whites must be beaten to firm peaks so they trap air and hold their shape. Under-beaten whites will deflate and make the topping flat and dense rather than light.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, sugar):
- Sweet potatofits better
- Asparagusfits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against butter, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
