Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the mixture
Combine egg yolks and sifted sugar in a bowl, stirring continuously for 5 minutes.
Whip egg whites until stiff.
Fold the stiff egg whites into the yolk mixture along with the flour.
Pipe the biscuits
Shape a stiff piece of white paper into a funnel, secure the funnel with a little paste, and let the paper dry.
Fill the funnel with the biscuit mixture.
Fold the paper over like a lid, cutting an opening 1 inch in diameter.
Pipe the mixture onto a stiff sheet of white paper in finger shapes, 1 inch wide and 3 inches long, leaving space between them.
Dust the biscuits with pounded sugar.
Bake and serve
Place the biscuits on a baking tin.
Bake in a moderate oven at 350°F (175°C) for 10 minutes.
Once cool, remove the biscuits and arrange them.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff foam that traps air and gives the biscuits their light, airy structure.
- Egg yolks
- Add richness and fat, and enrich the batter with flavor and tenderness.
- Sifted sugar
- Sweetens the biscuits and helps stabilize the batter while the yolks are beaten.
- Dry sifted flour
- Provides structure that sets the folded batter as it bakes.
The step that matters
Folding the stiff egg whites into the yolk mixture. Folding gently keeps the air trapped in the whipped whites. Stirring or deflating them makes the biscuits dense and flat instead of light and crisp.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
