Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Potato Starch Cake
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 batter
Preheat the oven to 350°F (175°C).
Beat the egg whites until stiff peaks form.
In a separate bowl, beat the egg yolks with 1/2 cup sugar until light and fluffy.
Add the flavoring, potato starch, and baking powder to the yolk mixture and mix well.
Gently fold the egg whites into the yolk mixture until combined.
Bake and assemble
Pour the batter into two greased cake pans.
Bake for 25-30 minutes or until a toothpick comes out clean.
Let the cakes cool, then spread whipped cream between the layers and on top.
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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites provide the air and structure that lift the light sponge.
- Potato starch
- Gives a tender, delicate crumb that is lighter than wheat flour.
- Baking powder
- Releases gas in the oven so the batter rises and stays airy.
- Sugar
- Sweetens the cake and helps stabilize the beaten egg yolks and whites.
The step that matters
Gently fold the egg whites into the yolk mixture. Egg whites hold air only while whipped. Vigorous stirring deflates them, leading to a dense, flat cake, so fold slowly with a spatula until just combined.
Swap the potato
How well each one fits the dish's main ingredients (egg, sugar):
- Sweet potatofits better
- Capsicumfits better
- Asparagusfits better
- Potatothe original
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
