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 ↓
Walnut Layer
Ingredients
Directions
Prepare the eggs
Separate the yolks and whites of the eggs, ensuring no yolk gets into the whites.
Sift the powdered sugar into the yolks and beat until thick and batter-like.
Add a pinch of salt to the egg whites and beat until very stiff.
Make the batter
Mix the pounded walnuts and grated lady fingers into the beaten yolks.
Gently fold in the stiff-beaten egg whites.
Bake and fill
Bake in layers and fill with almond or plain icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped with air give the cake its light, rising structure.
- Powdered sugar
- Sweetens the cake and thickens the beaten yolks into a batter.
- Walnuts
- Add body, moisture and a rich, nutty flavor to the crumb.
- Lady fingers or stale sponge cake
- Absorb moisture and add a tender, fine texture to the batter.
The step that matters
Folding in the stiff egg whites. The whites hold the air that lifts the layers. Folding gently keeps that air in; stirring or overmixing deflates the foam, leaving a dense, flat cake.
Swap the walnut
How well each one fits the dish's main ingredients (egg, sugar):
- Pecansfits better
- Almondfits better
- Chestnutfits about as well
- Walnutthe original
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
