Why it works: Vanilla and milk are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Wafers
Ingredients
Directions
Prepare the batter
Cut the vanilla pods into small pieces and pound them with some sugar.
Sift the mixture through a silk sieve into a bowl.
Add flour, egg yolks, and brandy to the bowl and stir until combined.
Dissolve the butter in warm milk and add it to the mixture, stirring until smooth and thin.
Cook the wafers
Heat an engraved iron over a charcoal fire and lightly grease it with butter or pork rind.
Pour a spoonful of batter onto the iron, ensuring it spreads evenly.
Close the iron and cook until golden brown, then flip to cook the other side.
Remove the wafer from the iron, trim the edges, and place it on a round piece of wood.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and help bind the batter while setting structure as the wafer cooks.
- Flour
- Provides the main structure that holds the thin wafer together.
- Butter
- Adds fat for richness and tenderness, and greases the iron so the wafer releases.
- Milk
- Thins the batter to a pourable consistency and adds moisture.
- Sugar
- Adds sweetness and contributes to browning on the iron.
The step that matters
Cooking the wafer on the iron. The iron must be hot and evenly greased, and the batter spread thinly. Too much batter or a cool iron gives thick, pale or sticking wafers, while the sugar browns quickly and can scorch if the heat is too high.
