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
Make the batter
Chop the vanilla pod into small pieces and pound it with the sugar in a mortar.
Sift the mixture through a fine sieve.
Combine the egg yolks, vanilla-sugar mixture, sifted flour, and brandy in a pan and mix the combined ingredients well.
Warm the milk in a basin and dissolve the butter in it, then pour the melted butter and warm milk into the pan with the other ingredients.
Mix until the batter is thin and glossy.
Cook the wafers
Heat the tongs over a stove or clear fire.
Rub the inside surfaces of the tongs with butter or oil.
Place a spoonful of batter in the tongs and close them immediately, ensuring the batter fills the wafer holes.
Cook over the fire, turning occasionally, until the wafers are done.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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 yolks
- Add richness and help bind the batter into a set, crisp wafer.
- Butter
- Adds fat and richness, giving the wafers a tender texture and flavor.
- Flour
- Provides the structure that holds the batter together as it cooks.
- Powdered sugar
- Sweetens the batter and helps it brown as it cooks over the fire.
- Milk
- Adds moisture so the batter flows into a thin, glossy consistency.
The step that matters
Closing the tongs on the batter. A thin batter needs a hot, lightly greased iron so it sets quickly and releases cleanly. Closing the tongs right after placing the batter lets it fill the pattern before it spreads or sticks.
