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
Prepare the potatoes
Boil the potatoes until white, mealy, and very tender.
Pass the hot potatoes through a colander.
Mix the mashed potatoes with the softened butter until well combined.
Make the custard

Add the grated lemon rind and juice to the egg mixture.

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 a soft, mealy body to the pudding.
- Butter
- Adds richness and a smooth, tender texture.
- Egg yolks
- Enrich the filling and help it set into a custard.
- Egg whites
- Whipped air lightens the mixture and helps it rise and set.
- Sugar
- Sweetens the pudding and softens the texture of the eggs.
- Lemon
- Adds acidity and aroma that brighten the sweet custard.
The step that matters
Folding in the beaten egg whites. Egg whites hold air only when whipped. Folding gently keeps that air in the mixture, so the pudding stays light instead of deflating and turning dense.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, sugar, lemon):
- Asparagusfits better
- Leekfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against butter, egg, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
