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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure that holds the waffle together as it sets.
- Yeast
- Ferments the batter so it rises and becomes light and airy.
- Eggs
- Add structure and richness, and the whites add lift when folded in.
- Milk
- Adds moisture and helps hydrate the flour into a pourable batter.
- Butter
- Adds fat for tenderness and flavor, and helps browning in the iron.
- Baking powder
- Releases gas during cooking to give the waffles additional rise.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air trapped in the whites. Stirring hard would deflate them, leaving the waffles denser and less light.
