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 ↓

Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Grate the Naples biscuits and mix with the blanched almonds, egg yolks, sugar, warmed butter, and orange-flower water.
Fill and bake
Fill the preserved oranges with the mixture.
Bake in a slow oven at 300°F (150°C).
If desired, sift sugar over them as soon as filled; otherwise, wipe them clean.
Custard option
For custard filling, let the mixture cool and do not bake the oranges.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Naples biscuits
- Provide the main crumb body that holds the filling together.
- Egg yolks
- Bind the mixture and set gently with heat, giving a tender, custard-like texture.
- Butter
- Adds fat for richness and a soft, moist crumb.
- Blanched almonds
- Add texture and a nutty flavor to the filling.
- Sugar
- Adds sweetness and helps the top brown lightly.
- Orange-flower water
- Adds a floral, aromatic note that suits the orange.
The step that matters
Choosing whether to bake. The record says both to bake the filled oranges in a slow oven and not to bake them for a custard filling, so decide which applies before starting. Egg yolks set gently as they heat, so a slow oven helps prevent curdling and overbaking.
