Why it works: Orange and peach match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 385 recipes. Both carry pinene, which smells pine, turpentine. The science ↓
Filbert Tart
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.
Make the batter
Grind the filbert kernels fine with the orange flower water.
Mix in the powdered sugar gradually.
Add the beaten egg yolks, then the flour.
Fold in the beaten egg whites gently.
Layer and bake
Spread the mixture into three layers, each ½ inch thick.
Bake in a moderate oven at 350°F (175°C).
Spread marmalade between each layer.
Finish
Ice the top with maraschino icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Filbert kernels
- Provide the main nutty body and bulk of the batter.
- Egg whites
- Whipped to trap air, giving the layers lift and a light texture.
- Egg yolks
- Add richness and help bind the batter as it sets.
- Powdered sugar
- Adds sweetness and fine texture to the batter.
- Flour
- Gives the layers enough structure to hold their shape when baked.
- Peach or apricot marmalade
- Adds fruity sweetness and moisture between the layers.
The step that matters
Fold in the beaten egg whites gently. Folding keeps the air whipped into the egg whites intact. Stirring vigorously deflates the foam, leaving the layers dense rather than light after baking.
Swap the filbert
How well each one fits the dish's main ingredients (orange, sugar, egg, flour, peach):

Fit is the average pairing score against orange, sugar, egg, flour, peach. Candidates are from the same food group and used in at least 100 recipes.
