Why it works: Chocolate and sugar are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

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.
Beat the egg whites until stiff.
Stir in the sugar, grated chocolate, and sifted flour.
Drop spoonfuls of the mixture onto buttered parchment paper.
Bake in a 400°F (200°C) oven until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a foam that traps air and gives the cake its lift.
- Sifted flour
- Provides the structure that holds the set batter together.
- Sugar
- Sweetens the batter and helps keep the cake moist and tender.
- Grated chocolate
- Adds flavor and richness, and melts into the batter as it bakes.
The step that matters
Beat the egg whites until stiff. Stiff whites hold the air that lifts the cake. Underbeaten foam collapses when folded in, and overbeaten whites turn dry and grainy, so the batter loses volume.
“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.
