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
Mix the flour with warm milk and strained yeast to form a soft, smooth paste.
Let the paste rise in a warm place until doubled in size.
Add the egg yolks and lemon zest rubbed into the sugar. Mix well.
Whip the reserved egg whites to stiff peaks.
Gently fold the whipped egg whites into the mixture.
Add 1 tablespoon of cream, beaten like the eggs. Mix gently.
Cook and serve
Preheat the waffle irons.
Lightly grease the waffle irons with butter.
Fill one side of the irons with the batter.
Cook over heat until golden brown.
Turn the irons to cook the other side.
Remove the wafers and place them on a plate.
Dust the wafers with powdered sugar.
Add any desired flavoring to the 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
- Flour
- Forms the paste and gives the waffles their structure as it sets in cooking.
- Yeast
- Produces gas during the rise, making the batter light and airy.
- Egg whites
- Whipped to stiff peaks, they add lightness and help the waffles puff.
- Egg yolks
- Add richness and fat, which tenderize the crumb and aid browning.
- Butter
- Greases the irons and adds richness and browning to the waffle surface.
- Sugar
- Adds sweetness and helps the waffles brown in the hot irons.
The step that matters
Folding in the whipped egg whites. Whipped whites hold air that makes the batter light. Stirring them in vigorously knocks out that air, leaving dense waffles, so fold gently until just combined.
