Why it works: Vanilla and chocolate 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 says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Make the dough
In a bowl, beat the eggs and mix in the sugar until well combined.
Melt the butter and chocolate together, then add to the egg mixture.
Stir in the flour and vanilla extract until a dough forms.
Shape and bake
Roll out the dough very thin on a floured surface.
Cut into desired shapes and place on a baking sheet.
Bake in the preheated oven until lightly golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add structure as they set during baking.
- Butter
- Adds fat for tenderness and a rich mouthfeel in the wafers.
- Flour
- Provides the structure that holds the thin wafers together.
- Sugar
- Sweetens the dough and helps the wafers brown lightly.
- Chocolate
- Adds chocolate flavour and fat that firm up as the wafers cool.
The step that matters
Rolling the dough very thin. Thin dough bakes quickly and crisps evenly; thick pieces stay soft in the centre and may scorch at the edges before they dry out.
“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.
