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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Line a pudding dish with light paste.
Boil and mash the potatoes, then pass through a sieve.
Make the filling
Add the eggs, lemon juice, and sugar to the potatoes.
Beat the mixture until very light.
Bake and serve
Bake for 20 to 30 minutes.
Sprinkle sugar over the top before serving.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
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, moist body of the pudding.
- Eggs
- Set the mixture when baked and add richness and structure.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sugar.
- Sugar
- Sweetens the pudding and helps the top brown lightly when baked.
The step that matters
Beat the mixture until very light. Beating traps air in the egg and potato mixture, which helps the pudding rise and gives it a light, soft texture. Under-beating leaves it dense.
Swap the potato
How well each one fits the dish's main ingredients (egg, lemon, sugar):
- Asparagusfits better
- Arrowrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against egg, lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
