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 ↓
Lemon-potato Pie
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the filling
Preheat the oven to 350°F (175°C).
Grate the raw potato and lemon, then combine them in a bowl.
Add sugar and water to the mixture and stir well.
Assemble and bake
Pour the mixture into a pie crust and cover with the second crust.
Bake for about 30-40 minutes or until golden brown.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Raw potato
- Gives the filling body and bulk as it bakes.
- Lemon
- Adds acidity and aroma that cut through the sweetness.
- Sugar
- Sweetens the filling and helps the top brown as it bakes.
- Pie crusts
- Enclose the filling so it bakes as a sealed pie.
The step that matters
Bake until the potato is fully cooked. Golden brown color can appear before raw potato is fully cooked through. Starch in the potato only softens and sets properly once it is heated thoroughly, so the pie should be checked for doneness, not just color.
Swap the potato
How well each one fits the dish's main ingredients (lemon, sugar):
- Arrowrootfits better
- Sweet potatofits better
- Kalefits better
- Potatothe original
Fit is the average pairing score against lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
