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 ↓
Biscuit À LA Cuillière
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.
Make the batter
Combine the yolks of 4 eggs with 4 ounces of pounded sugar and grated peel of 1 lemon in a small bowl.
Mix the mixture with a spatula for 10 minutes.
Beat 4 egg whites until very stiff.
Fold a quarter of the stiff whites into the yolk mixture.
Gently mix in the remaining whites and 2 ounces of flour until smooth.
Shape and bake
On half‑sheets of paper, form biscuits about 3 inches long and no larger than your finger.
Cover the biscuits with fine sugar.
Place the sheets on a baking plate in a 350°F (175°C) oven with the door half‑open until the surface of the biscuits becomes glossy.
After 7‑8 minutes, close the oven.
Bake until the biscuits are lightly browned.
Finish
Once cool, carefully remove the biscuits with a thin knife.
Place them back‑to‑back to preserve their glossy sides.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Enrich the batter and add richness and colour to the biscuits.
- Egg whites
- Whipped to stiff foam, they give the biscuits their light, airy structure.
- Pounded sugar
- Sweetens the batter and helps stabilise the whipped egg foam.
- Flour
- Provides light structure so the biscuits hold their shape while baking.
The step that matters
Folding the whites into the yolk mixture. Overmixing or deflating the whipped egg whites removes the air that makes the biscuits light, so fold gently and only until smooth.

Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
