Why it works: Biscuit and almond match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 388 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
To Fill Preserved Oranges
Ingredients
Directions
The book says “a very slow oven”. The 300°F in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Grate the Naples biscuits and mix with blanched almonds, egg yolks, sugar, warmed butter, and orange-flower water.
Fill and bake
Fill the preserved oranges with the mixture.
Bake in a very slow oven (300°F / 150°C).
Finish
If desired, sift sugar over them as soon as filled; otherwise, wipe them clean.
If using custard to fill, do not bake the oranges; simply fill them when cooled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Naples biscuits
- Provide the bulk and crumbly body of the filling.
- Egg yolks
- Bind the mixture and help it set into a soft, tender texture when baked.
- Butter
- Adds fat for richness and a moist, smooth texture.
- Blanched almonds
- Add body and a nutty texture to the filling.
- Sugar
- Adds sweetness that balances the orange flavour.
The step that matters
Bake in a very slow oven. Egg yolks set gently at low heat. Too much heat can curdle them or dry out the filling, leaving it grainy instead of soft and smooth.
