Why it works: Sugar and chocolate 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 ↓
Chocolate Puffs
Ingredients
Directions
The book says “a warm oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the egg whites to a stiff froth.
Gradually stir in the powdered sugar and cornstarch.
Fold in the grated chocolate.
Bake
Drop the mixture by dessert spoonfuls, one inch apart, onto buttered baking sheets.
Bake in a warm oven at 400°F (200°C) for 15 minutes.

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 stiff foam that traps air, giving the cookies their light, airy lift.
- Powdered sugar
- Sweetens the batter and dissolves easily into the whipped whites for a smooth mixture.
- Cornstarch
- Stabilizes the batter and helps the cookies keep a tender, soft interior texture.
- Chocolate
- Adds chocolate flavor and melts slightly during baking for richness.
The step that matters
Beat the egg whites to a stiff froth. Egg whites must be whipped until they hold stiff peaks, since the foam traps air that gives the cookies lift. Under-whipped or greasy whites will spread and bake flat and dense.
