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 ↓

Butter and flour 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
- Set the batter into a structure that holds its shape in the hot fat.
- Flour
- Provides structure so the fried pieces hold together rather than collapsing.
- Milk
- Adds moisture and softness to the batter.
- Butter
- Adds fat for richness and a tender crumb.
- Sugar
- Adds sweetness and helps the outside brown in the frying fat.
The step that matters
Frying in hot lard. The lard must be hot enough that the spoonfuls seal and puff quickly; if it is too cool they soak up grease and turn heavy, while if it is too hot the outside browns before the centre sets.
Swap the lemon

Fit is the average pairing score against milk, egg, butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
