Why it works: Potato and lemon are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 2,230 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Potato Pudding
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the potatoes
Boil the potatoes until tender.
Dry the boiled potatoes well.
Rub the potatoes through a sieve.
Make the mixture
Mix the sieved potatoes with sugar, butter, and the yolks of the eggs.
Beat the egg whites to a froth.
Add the juice and grated rind of the lemon to the froth.
Combine everything well.
Pour into a well-buttered mold.
Bake
Bake for 30 minutes in a moderately hot oven (350°F / 175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk and soft, smooth body of the pudding.
- Butter
- Adds richness and fat, giving a tender texture and moist crumb.
- Sugar
- Adds sweetness and helps keep the pudding moist.
- Eggs
- Yolks enrich and bind the mixture, while whites lighten it and help it set.
- Lemon
- Adds acidity and aroma that brighten the sweet, rich mixture.
The step that matters
Beating the egg whites to a froth. Whipped egg whites trap air that lightens the mixture and helps it rise and set in the oven. Under-beaten whites add less lift, and over-beaten whites become dry and hard to fold in evenly.
Swap the potato
How well each one fits the dish's main ingredients (sugar, butter, egg, lemon):
- Asparagusfits better
- Leekfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against sugar, butter, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
