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 ↓

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lightness, while yolks add richness and help bind the batter.
- Flour
- Forms the main structure of the waffle as its proteins set during baking.
- Milk or cream
- Provides moisture and hydrates the flour so the batter can flow and set.
- Butter
- Adds fat for tenderness and flavor, and browns the waffle's surface.
- Baking powder
- Releases gas that makes the waffle rise and become light and open-textured.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air beaten into the whites. Stirring vigorously deflates them, which leads to a dense, flat waffle.
Swap the walnut
How well each one fits the dish's main ingredients (egg, flour, milk, butter):
- Almondfits better
- Walnutthe original
- Pecansfits about as well
- Milletfits about as well
Fit is the average pairing score against egg, flour, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
