Why it works: Flour and sugar 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 ↓
French Biscuits— No. II
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Separate the egg whites and yolks, then beat them separately.
Make and bake the biscuits
Gradually stir in the flour and sugar.
Add the minced orange peel and mix well.
Drop spoonfuls of the mixture onto parchment paper.
Bake until golden, then let cool.
Store
Pack in a box for later use.

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
- Eggs
- Whipped separately, the whites and yolks add lift and structure to the batter.
- Flour
- Provides the structure that holds the biscuits together as they bake.
- Sugar
- Adds sweetness and helps the biscuits brown as they bake.
- Minced orange peel
- Adds citrus aroma and flavour throughout the batter.
The step that matters
Beating the egg whites and yolks separately. Whites beaten to a stable foam trap air that gives the biscuits lift. Overmixing once the flour goes in can deflate that foam and make the biscuits dense.
Swap the orange
How well each one fits the dish's main ingredients (egg, flour, sugar):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against egg, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
“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.
