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 ↓
Sweet Wafers
Ingredients
Directions
Prepare
Preheat the wafer iron and grease it with butter.
Make the batter

Cook the wafers

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Bind the batter and add structure as the wafers set.
- Flour
- Provides the structure that holds the thin wafer together as it cooks.
- Sugar
- Adds sweetness and helps the wafers brown as they cook.
- Melted butter
- Adds richness and fat, helping the batter cook smoothly and release from the iron.
The step that matters
Cook until done, then roll while hot. Wafers set and firm as they cool, so rolling them over a stick needs to happen while they are still warm and pliable. Left too long, they become brittle and crack.
