Why it works: Egg and bread are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 22,662 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓
Brown Bread Biscuits
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).
Separate the egg whites from the yolks.
Make the batter
In a bowl, mix the sugar and lemon raspings with the yolks until light and very white.
Whisk the egg whites until stiff peaks form.
Gently fold the egg yolk mixture into the whipped egg whites.
Sift the flour and mix it with the crumbled brown bread.
Fold the flour and brown bread mixture into the egg mixture.
Bake
Spoon the batter into small tins shaped like hearts, ovals, or squares.
Bake with six sheets of paper under the tins until done.

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 whites give the biscuits their light, airy structure, while the yolks add richness.
- Sugar
- Sweetens the batter and helps the yolks whip to a pale, thick mixture.
- Flour
- Provides the structure that holds the batter together as it bakes.
- Brown bread
- Adds crumb texture and a toasty, slightly earthy flavour to the biscuits.
- Lemon raspings
- Adds bright aroma and citrus flavour that balances the sweetness.
The step that matters
Folding the yolk mixture into the whipped whites. Folding gently keeps the air trapped in the whites. Stirring or deflating the foam makes the biscuits dense instead of light.
