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
In a pan, combine flour and warm milk mixed with strained yeast.
Make a soft, smooth paste and let it rise in a warm place.
Once risen, add egg yolks and lemon zest rubbed into the sugar and butter.
Whip egg whites to stiff peaks and gently fold into the mixture.
Optionally, add cream and mix well.
Return the paste to rise again until doubled in size.
Cook and serve
Preheat your waffle irons and lightly grease with butter.
Fill one side of the irons with the batter and cook over heat.
Once golden, turn the wafers and cook until done.
Remove wafers, place on a plate, and dust with powdered sugar.

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
- All-purpose flour
- Provides the starch and gluten structure that holds the waffles together.
- Egg whites
- Whipped to stiff peaks, they add lightness and help the waffles rise and stay airy.
- Egg yolks
- Add richness, tenderness and colour to the batter.
- Butter
- Adds fat for tenderness and flavour, and helps the waffles brown.
- Yeast
- Ferments the paste so it rises, giving the waffles an airy, light texture.
- Sugar
- Adds sweetness and helps the waffles brown in the iron.
The step that matters
Folding in the egg whites. Whipped whites hold air that gives lightness. Stirring them vigorously knocks that air out, while gentle folding keeps the batter light and well risen.
