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 ↓
Silver 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.
Make the filling
Preheat the oven to 350°F (175°C).
In a bowl, combine the grated potato, lemon juice, lemon rind, beaten egg white, sugar, and cold water.
Pour the mixture into a pie crust and bake until set.
Top and finish
Once baked, spread the frothed egg whites on top, sweetened and flavored with lemon.
Return to the oven and brown the top.
Before serving, add small pieces of jelly or jam on top.

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
- White potato
- Its grated starch thickens the filling as it bakes, giving the pie body.
- Lemon juice and rind
- Provides the sharp acidity and bright aroma that define the lemon flavor.
- Egg white
- Helps bind the filling and sets during baking to give it structure.
- White sugar
- Sweetens the filling and balances the acidity of the lemon.
- Egg whites, frothed
- Whipped foam forms the topping, which browns in the oven for a light, crisp finish.
The step that matters
Bake the filling until set. Underbaking leaves the grated potato and egg mixture runny, so the filling will not hold its shape when cut. Baking until set lets the proteins coagulate and the starch firm up.
Swap the potato
How well each one fits the dish's main ingredients (lemon, egg, sugar):
- Asparagusfits better
- Arrowrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against lemon, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
