Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Chocolate Wafers
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, cream together the brown sugar, granulated sugar, and butter.
Add the grated chocolate, egg, and vanilla extract; mix well.
Gradually add enough flour to form a stiff dough.
Shape and bake
Roll the dough very thin on a floured surface.
Cut into desired shapes and place on a baking sheet.
Bake in the preheated oven until crisp.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and helps the dough cream and hold together.
- Brown sugar
- Adds sweetness and moisture, and contributes to a chewy-crisp texture.
- All-purpose flour
- Provides structure, forming the stiff dough that holds the wafer shape.
- Egg
- Binds the dough and adds richness to the batter.
- Grated chocolate
- Adds chocolate flavor and fat to the dough.
The step that matters
Roll the dough very thin. Thin dough dries out and crisps during baking, while thick dough stays soft in the centre. Uneven thickness causes uneven browning.
“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.
