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 ↓
Plain Waffles
Ingredients
Directions
Make the batter
Sift together the flour, baking powder, and salt.
Stir in the milk, beaten egg yolks, and melted butter.
Fold in the stiffly beaten egg whites.
Cook and serve
Heat the waffle iron and grease both sides.
Pour a spoonful of batter into each section, close the iron, and turn it immediately.
Cook until the waffles are evenly browned and very crisp.
Serve hot with butter, sugar, syrup, or fruit.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that holds the waffle together as it sets.
- Baking powder
- Releases gas during cooking so the waffles rise and turn light and open.
- Egg yolks
- Add richness and help bind the batter while adding tenderness.
- Egg whites
- Whipped to stiff peaks, they trap air that lightens the batter and helps it rise.
- Milk
- Hydrates the flour so the batter forms and cooks into a tender crumb.
- Butter
- Adds fat for flavor and helps the waffles brown and crisp on the iron.
The step that matters
Folding in the egg whites. Stirring instead of folding deflates the whipped whites, removing the trapped air that makes the waffles light. Fold gently and only until no white streaks remain.
