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 ↓

Directions
Make the batter
In a bowl, mix the flour, baking powder, and salt.
In another bowl, beat the egg yolks and add melted butter and milk.
Combine the wet ingredients with the dry ingredients until smooth.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Cook
Cook in a preheated waffle iron until golden brown.

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 main structure that holds the waffle together as it cooks.
- Baking powder
- Releases gas during cooking, making the waffles rise and turn light.
- Eggs
- Yolks add richness and binding, while whipped whites add lift and a airy texture.
- Melted butter
- Adds fat for tenderness and flavor, and helps browning in the iron.
- Milk
- Hydrates the flour so the batter forms and cooks into a tender crumb.
The step that matters
Folding in the egg whites. Whipped whites hold air that gives lift. Stirring them in vigorously knocks out that air and leaves dense waffles, so fold gently until just combined.
