Why it works: Potato and olive are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 6,458 recipes. Both carry 2-undecenal, which smells sweet. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Grease a springform or cake pan with olive oil or butter.
Make the batter
Beat the egg yolks and sugar together until very light.
Add the lemon rind and juice, then mix in the matzo meal and potato flour alternately, ensuring to mix well after each addition.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the beaten egg whites into the yolk mixture.
Bake
Pour the batter into the prepared pan and bake in the preheated oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites give the cake its light, airy structure, while yolks add richness and color.
- Granulated sugar
- Sweetens the batter and helps beat the yolks to a light, stable foam.
- Matzo meal
- Provides the light starch and body that holds the cake together without wheat flour.
- Potato flour
- Adds tenderness and binding in place of wheat flour, keeping the crumb soft.
- Lemon juice
- Adds acidity that brightens the flavor and balances the sweetness.
The step that matters
Folding in the egg whites. Egg whites hold air only when whipped to stiff peaks. Folding gently keeps that air in the batter, so the cake rises and stays light instead of deflating.
Swap the potato
How well each one fits the dish's main ingredients (egg, sugar, flour, lemon, olive):
- Arrowrootfits better
- Shallotfits better
- Asparagusfits better
- Potatothe original
Fit is the average pairing score against egg, sugar, flour, lemon, olive. Candidates are from the same food group and used in at least 100 recipes.
