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 ↓
Fannie's 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.
Prepare the filling
Preheat the oven to 350°F (175°C).
In a bowl, combine the grated potato, lemon juice, lemon rind, beaten egg white, and cold water.
Line a pie plate with crust and pour the mixture into it.
Bake until done.
Make the meringue and finish
In another bowl, beat the egg whites with the sugar and rose water until stiff peaks form.
Spread the meringue over the baked pie and return it to the oven.
Bake until the meringue is light brown.
Top with strips of jelly before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potato
- Grated potato thickens the lemon filling and gives it a smooth, custard-like body.
- Lemon juice and rind
- Provides the sharp acidity and bright aroma that flavour the filling.
- Egg white
- Helps bind and set the filling as it bakes.
- Egg whites (meringue)
- Whipped into stiff peaks, they form the airy topping that browns in the oven.
- Sugar
- Sweetens the meringue and helps it stay stable and brown lightly.
The step that matters
Beat the meringue to stiff peaks. Egg whites need to be whipped until firm peaks form so the meringue holds its shape and bakes into a light, airy topping. Under-whipped whites collapse and weep.
Swap the potato
How well each one fits the dish's main ingredients (lemon, egg, sugar, rose):
- Arrowrootfits better
- Sweet potatofits better
- Capsicumfits better
- Potatothe original
Fit is the average pairing score against lemon, egg, sugar, rose. Candidates are from the same food group and used in at least 100 recipes.
