Why it works: Butter and milk 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 dough together as it fries.
- Baking powder
- Releases gas during frying, lightening the crullers' texture.
- Butter
- Adds fat for richness and a tender crumb.
- Sugar
- Adds sweetness and helps the crust brown during frying.
- Egg yolks
- Add richness and emulsify the dough for a smooth texture.
- Whole eggs
- Help bind the dough and add structure.
The step that matters
Fry the crullers until golden brown. Frying at the right temperature cooks the centre through while the outside browns. If the oil is too cool, the crullers absorb excess oil and turn greasy; if too hot, the outside darkens before the inside sets.
Swap the mace
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, milk, lemon):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against flour, butter, sugar, egg, milk, lemon. Candidates are from the same food group and used in at least 100 recipes.
