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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Beat the egg whites to stiff peaks.
Make the filling
Combine the hot, riced potatoes with the butter and mix well.
In a separate bowl, beat the egg yolks and sugar together until light.
Add the lemon juice and rind to the yolk mixture, then fold in the egg whites gently.
Pour the mixture into a pie plate lined with pastry and bake until set.
Let cool before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and set the custard, while whipped whites lighten the texture.
- Potatoes
- Riced potatoes give the pudding its body and a smooth, dense crumb.
- Sugar
- Sweetens the filling and helps the yolks whip up light and airy.
- Butter
- Adds fat for richness and a tender, moist texture.
- Lemon
- Juice and rind add acidity and bright aroma that balance the sweetness.
The step that matters
Folding in the egg whites. Whites hold air from whipping, and overmixing or stirring them vigorously deflates that foam. Gentle folding keeps the pudding light before it bakes and sets.
Swap the potato
How well each one fits the dish's main ingredients (egg, sugar, butter, lemon):
- Asparagusfits better
