Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Flemish Wafers
Ingredients
Directions
Make the batter
Combine flour and warm milk mixed with strained yeast in a bowl to form a soft, smooth paste.
Let the paste rise in a warm place until doubled in size.
Add egg yolks and lemon zest rubbed into the sugar, then mix well.
Whip egg whites to stiff peaks, then gently fold into the mixture.
If desired, add 1 tablespoon of cream, beaten like the eggs.
Cook and serve
Preheat waffle irons and lightly grease them with butter.
Fill one side of the irons with batter, cook until golden brown, then flip to cook the other side.
Remove the wafers, place them on a plate, dust with powdered sugar and any desired flavoring.

Flour and butter 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
- Flour
- Forms the structure of the batter paste that holds the wafers together.
- Egg whites
- Whipped to stiff peaks, they lighten the batter and help the wafers rise and stay tender.
- Egg yolks
- Add richness and help bind the batter while adding color and flavor.
- Butter
- Adds richness and flavor, and greasing the irons helps the wafers release and brown.
- Yeast
- Makes the paste rise, giving the wafers an airy, light texture.
- Sugar
- Adds sweetness and helps the wafers brown as they cook.
The step that matters
Folding in the whipped egg whites. Stiff whites hold air that lightens the batter. Folding gently keeps that air in, while stirring hard would deflate the batter and make the wafers dense.

Fit is the average pairing score against flour, sugar, butter, egg, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
