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
- Egg whites
- Whipped to stiffness, they trap air that lightens the batter and helps the waffles rise.
- Baking powder
- Releases gas in the batter, causing the waffles to rise and become light.
- Flour
- Provides the structure that holds the waffle together as it sets.
- Butter
- Adds fat for richness and tenderness, and helps the waffles brown.
- Egg yolks
- Add richness and emulsify the batter, contributing to a tender crumb.
The step that matters
Fold in the egg whites gently. Whipped egg whites hold air that gives the waffles lift. Vigorous stirring deflates the foam, leaving dense, flat waffles. Folding just before cooking keeps the air in the batter.
