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 ↓
Chocolate Wafers
Ingredients
Directions
The book says “a very moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Beat the egg whites and powdered sugar together until very light.
Slowly add the grated chocolate and stir until combined.
Gently fold in the sifted flour.
Bake
Drop tiny spoonfuls onto a buttered baking pan, spacing them apart.
Bake in the preheated oven until dry but not browned.

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
- Egg whites
- Whipped to create air and light structure that lifts the wafers.
- Powdered sugar
- Sweetens the batter and helps stabilise the whipped egg whites.
- Grated chocolate
- Adds chocolate flavour and colour to the batter.
- All-purpose flour
- Provides light structure so the wafers set rather than spread away.
The step that matters
Folding in the flour. Folding gently keeps the air beaten into the egg whites. Stirring hard would deflate the batter and make the wafers dense and flat.
