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
- All-purpose flour
- Provides the structure that sets as the waffle cooks.
- Milk or cream
- Hydrates the flour and gives the batter its liquid base and tenderness.
- Butter
- Adds richness and fat, helping the waffle brown and crisp at the surface.
- Baking powder
- Releases gas when heated, lifting the batter so the waffle rises.
The step that matters
Fold in the beaten egg whites gently. Beaten whites trap air that gives the waffles lift. Overmixing deflates them, leaving the waffles dense and flat.
