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 ↓

Directions
The book says “a gentle oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
In a marble mortar, pound the almonds until fine.
Add the flour and sugar.
Break in 2 or 3 egg whites to moisten and pound together.
Add 4 whole eggs and mix well.
Break 4 more eggs and add the yolks to the mixture, keeping the whites aside.
Melt the butter and mix it into the paste until smooth and free of lumps.
Whisk the reserved egg whites to a froth and fold them into the mixture.
Bake
Pour the batter into small round or oval molds.
Sprinkle finely cut white almond prawlings on top.
Bake in a moderate oven at 350°F (175°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure as they set and add richness and lift from the whipped whites.
- Almonds
- Supply the bulk and nutty flavour of the batter, forming its paste-like body.
- Flour
- Gives the batter body so it holds its shape as it bakes.
- Butter
- Adds fat for a tender texture and rich flavour.
- Powdered loaf sugar
- Sweetens the batter and helps it brown lightly in the oven.
The step that matters
Folding in the whipped egg whites. Whites beaten to a froth trap air that expands in the oven and gives the biscuits lightness. Overmixing or deflating them during folding loses that lift, leaving dense biscuits.
