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 ↓
Fine Savoy Biscuits
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Separate the yolks from the whites of the eggs and place the yolks in a bowl.
Add the powdered sugar and lemon rind to the yolks, then mix and stir for 10 minutes.
Whisk the egg whites in a copper bowl until they are almost stiff.
Gently fold the egg whites into the yolk mixture using a wooden spoon.
Sift the flour into the mixture and stir until just combined.
Shape and bake
Using a small teaspoon, scoop out a spoonful of batter and pull it along parchment paper, shaping it into a 3-inch long and ½-inch wide biscuit.
Sprinkle sugar over the biscuits before baking.
Bake in a very hot oven at 400°F (200°C), watching closely to prevent burning.
Cut the biscuits off the paper while they are still hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped by whisking give the batter its light, airy structure.
- Powdered sugar
- Sweetens the batter and helps give the biscuits a delicate, tender crumb.
- Fine flour
- Provides the starch and structure that hold the biscuit shape after baking.
- Lemon rind
- Adds aromatic citrus oils that flavour the batter.
The step that matters
Folding the egg whites into the yolk mixture. Folding gently preserves the air whisked into the whites; stirring or beating hard would deflate the batter and make the biscuits flat and dense.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, flour):
- Raisinfits better

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