Why it works: Milk and butter 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 ↓
Wafers, Flemish
Ingredients
Directions
Prepare the flavored sugar
Rub sugar on lemon rind until yellow part removed, then crush to powder.
Make the dough
In a bowl, mix flour, salt, and flavored sugar.
Gradually add lukewarm milk and yeast, mixing to form a soft dough.
Cover dough and let rise on hearth until doubled in size.
Work in softened butter, beaten egg yolks, then fold in beaten egg whites.
Bake and serve
Bake wafers for 3 to 4 minutes until golden.
Serve hot, dusting 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
- Flour
- Forms the structure of the dough that holds the wafers together.
- Yeast
- Produces gas that makes the dough rise and become light.
- Butter
- Adds fat that tenderizes the wafers and enriches their flavor.
- Egg yolks
- Add richness and help bind the dough with fat and moisture.
- Egg whites
- Trap air when folded in, adding lightness to the wafers.
- Sugar
- Sweetens the wafers and promotes golden browning in the oven.
The step that matters
Let the dough rise until doubled. Yeast needs enough time to produce gas and expand the dough; rising too little leaves the wafers dense, while the dough should be covered so its surface does not dry out.

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