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 ↓
Doughnuts
Ingredients
Directions
Make the dough
In a bowl, beat the eggs and sugar together until well combined.
Add the sweet milk and melted butter, mixing until smooth.
Stir in the salt and baking powder.
Gradually add flour until a soft dough forms.
Fry and finish
Heat deep fat in a frying pan.
Drop spoonfuls of dough into the hot fat and fry until golden brown.
Remove from fat and dip briefly in boiling water to remove excess grease.
Place in a baking pan in a warm oven with the door open to dry for a few minutes.
Roll in sugar flavored with cinnamon before serving.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- Bind the dough and add richness and structure to the batter.
- Sugar
- Adds sweetness and helps the doughnuts brown in the hot fat.
- Butter
- Adds fat for tenderness and a richer flavor in the dough.
- Baking powder
- Releases gas that lightens the dough so the doughnuts rise and stay tender.
- Flour
- Forms the structure of the dough, giving it body so it holds its shape when fried.
The step that matters
Frying the dough in hot fat. If the fat is not hot enough, the doughnuts absorb excess oil and turn greasy; if it is too hot, the outside browns before the centre cooks. Steady heat gives a golden crust and a fully cooked interior.
