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
- Flour
- Provides the structure that holds the batter together as it cooks.
- Egg whites
- Beaten to stiff peaks, they add lightness and help the batter puff when fried.
- Butter
- Adds richness and fat, contributing flavour and a tender texture.
- Milk
- Hydrates the flour to form a smooth, pourable batter.
The step that matters
Folding in the egg whites. Stiffly beaten whites hold air that gives lightness. Folding gently keeps that air in; stirring vigorously deflates the foam and produces a denser, flatter batter.
