Why it works: Filbert and butter work together. They rank in the top 11% of all ingredient pairs, and cooks put them together in 52 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Filbert Taet 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.
Prepare the filberts and yolks
Blanch and finely grind the filberts in a mortar.
In a bowl, beat the egg yolks with the powdered sugar until thick.
Make the batter
Add the ground filberts and grated lemon peel to the yolk mixture.
In a separate bowl, beat the egg whites until very stiff.
Gently fold the sifted flour into the egg whites.
Combine the egg white mixture with the yolk mixture.
Pour the batter into a well‑buttered and paper‑lined cake pan.
Bake and finish
Bake at 350°F (175°C) until golden.
Ice the cake and garnish with whole filberts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Filberts
- Finely ground nuts add body, richness and a nutty flavour to the crumb.
- Egg yolks
- Add richness and fat, and with the sugar form a thick, tender base.
- Egg whites
- Whipped stiff, they trap air that lifts the cake as it bakes.
- Flour
- Provides light structure that holds the cake together once baked.
- Powdered sugar
- Sweetens the batter and dissolves easily into the yolks for a fine texture.
The step that matters
Whipping and folding the egg whites. Whites must be beaten until very stiff, and the flour and batter folded in gently, so the air bubbles survive. Those bubbles are what make the cake rise and stay light; overmixing deflates them and leaves a dense cake.
Swap the filbert
How well each one fits the dish's main ingredients (egg, sugar, lemon, flour, butter):
- Almondfits better
- Pistachiofits better
- Milletfits better
- Filbertthe original
Fit is the average pairing score against egg, sugar, lemon, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
