Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Grate the peel of the lemons or oranges over the sugar and let it dry.
Separate the eggs into two bowls, one for the whites and one for the yolks.
Check each egg for freshness before breaking.
Make the batter
Combine the sugar with the yolks and mix with two wooden spoons.
Whip the egg whites until very firm, adding a pinch of calcined alum to stabilize them.
Fold half of the whipped egg whites into the yolk mixture.
Sift the flour over the egg mixture and gently fold in the remaining egg whites.
Bake
Butter a mold and dust it with fine sugar.
Pour the batter into the mold gradually.
Place the mold on a baking dish with ashes.
Bake for about 1 hour without moving it until fully done.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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 whites create the airy structure, while yolks add richness and set the crumb.
- Fine dry flour
- Provides the starch that sets the structure as the biscuit bakes.
- Sugar
- Sweetens the batter and helps give the biscuit a tender, delicate crumb.
- Calcined alum
- Stabilizes the whipped egg whites so they hold their foam during folding and baking.
The step that matters
Folding the whipped egg whites. Folding gently keeps the air in the whipped whites. Overmixing deflates the foam, so the biscuit rises less and bakes up dense.
