Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Neapolitan Paste
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.
Prepare the almond paste
Blanch and pound the sweet and bitter almonds to a smooth paste, adding a little cold water as needed to prevent oiling.
Make the dough
In a bowl, combine the flour, sugar, butter, lemon rind, and a pinch of salt.
Stir in the yolks of the eggs and mix until a smooth paste forms.
Set aside in a cool place for about 1.5 hours.
Shape and bake
Roll out the paste thinly and cut into squares or rounds.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the dough together as it bakes.
- Butter
- Adds fat that tenderises the dough and helps it brown.
- Egg yolks
- Bind the dough and add richness and colour.
- Sweet almonds
- Form the bulk of the paste, adding nutty flavour and body.
- Bitter almonds
- Add a deeper, sharper almond aroma to the paste.
- Castor sugar
- Sweetens the dough and aids golden browning in the oven.
The step that matters
Adding water to the almond paste. Pounding almonds releases oil, which can separate and make the paste greasy. A little cold water keeps the paste smooth and emulsified, so the dough bakes evenly.
