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.
Make the batter
Beat the egg whites and powdered sugar together until very light.
Slowly add the grated chocolate and mix well.
Stir in the sifted flour until combined.
Bake
Drop tiny spoonfuls onto a buttered baking sheet, spacing them apart.
Bake in a moderate oven at 350°F (175°C) 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 with sugar to trap air, giving the wafers their light, crisp structure.
- Powdered sugar
- Sweetens the batter and dissolves readily into the whipped whites, helping them stay stable.
- Baker's chocolate
- Provides the chocolate flavor and deep color of the wafers.
- Flour
- Adds just enough body to set the batter so the wafers hold their shape while baking.
The step that matters
Bake until dry but not browned. Baking past the point of dryness or into browning can make the wafers bitter and brittle, while underbaking leaves them soft and sticky. Watching for a dry surface without color keeps the texture crisp and the chocolate flavor clean.
