Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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 bind the batter with the sugar.
- Egg whites
- Beaten in to lighten the batter and give it airy structure.
- Flour
- Provides the structure that sets the wafer as it cooks.
- Sugar
- Adds sweetness and helps the wafers brown to golden.
- Butter
- Adds fat for flavor and a tender, crisp texture.
The step that matters
Remove from the iron and roll while hot. Wafers become brittle as they cool and cannot be shaped easily, so they must be rolled immediately after leaving the iron while still pliable.
“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.
