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 ↓
Airy Waffles
Ingredients
Directions
Preheat your waffle iron.
In a large bowl, rub the butter into the flour and add the salt.
In another bowl, beat the eggs until light and mix the yolks with the milk.
Gradually add the milk mixture to the flour, beating well.
Just before baking, fold in the baking powder and the well-beaten egg whites.

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 as its proteins and starches set around the air and steam.
- Eggs
- Add structure and richness, and the whipped whites add lightness to the batter.
- Milk
- Adds moisture and loosens the batter so it spreads and cooks through.
- Butter
- Adds fat for tenderness and richness, and helps the waffles brown.
- Baking powder
- Releases gas when heated, helping the waffles rise and become airy.
The step that matters
Folding in the baking powder and egg whites just before baking. Baking powder starts releasing gas once it is wet and warm, and whipped whites deflate when overmixed. Folding gently and cooking right away keeps the air and lift in the batter.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
