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 a stiff froth.
Make the filling
In a bowl, mix the hot potato with the butter until well combined.
Add the beaten egg yolks and sugar to the potato mixture, then stir in the lemon juice and rind.
Gently fold in the beaten egg whites.
Pour the mixture into a pie plate lined with pastry.
Bake and serve
Bake until set and lightly golden.
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 add richness and set the custard, while whipped whites lighten the texture.
- Potato
- Provides the bulk and a soft, smooth body for the filling.
- Sugar
- Adds sweetness and helps the filling brown lightly in the oven.
- Butter
- Adds fat for a rich mouthfeel and a tender texture.
- Lemon
- Adds acidity and aroma that brighten the sweet filling.
The step that matters
Gently fold in the beaten egg whites.. Whipped whites trap air that gives the pudding lift. Stirring them vigorously deflates the foam, leaving a denser, heavier result.
Swap the potato
