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 ↓
Flemish Wafers
Ingredients
Directions
Make the batter
In a deep pan, mix flour with warmed milk and fresh yeast until smooth.
Place the mixture in a warm spot to rise.
Add beaten egg yolks, cream butter, and pounded sugar to the mixture.
Gently fold in the whisked egg whites.
Let the mixture rise again until nearly doubled in size.
Cook and serve
Heat and grease the wafer irons with a little butter.
Fill one side of the irons with the mixture and close them.
Cook until one side is done, then turn to cook the other side until golden.
Remove the wafers and place them on a plate.
While hot, sift grated sugar over the wafers.

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 once mixed with milk and yeast.
- Fresh yeast
- Produces gas that makes the batter rise and turn airy.
- Egg yolks
- Add richness and help bind the batter for a tender texture.
- Egg whites
- Whisked air lightens the batter and helps the wafers puff.
- Butter
- Adds fat for richness and a tender, flavorful crumb.
The step that matters
Folding in the egg whites. Egg whites hold air only when whisked well; overmixing or deflating them while folding loses the lift the batter needs to rise and stay light in the iron.
