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 ↓
Quick Doughnuts
Ingredients
Directions
Make the dough
Set the water (milk) to boil with butter and salt; when it starts boiling, remove from heat, add the flour and at the same time, start stirring with a spoon.
Return to slow heat and keep stirring until the mixture starts to come off the sides of the pan.
Let cool, add lemon juice and 4 eggs previously mixed with sugar. Mix everything well.
Fry and finish
With a well greased teaspoon, take spoonfuls of the mixture and drop into hot oil to fry.
Fry until golden-brown and then sprinkle with vanilla flavored confectioner's sugar.
Nutrition, whole recipe (rough)
Counts 8 of 9 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 8 portions

|---|---|---|
| Flour | 1 cup (125g) all-purpose | 455 |
| Milk | 1 cup (244ml) whole | 149 |
| Olive Oil | 1 tbsp (14g) | 119 |
| Butter | 1 tbsp (14g) | 102 |
| Egg | 1 large egg (50g) | 78 |
| Sugar | 1 tbsp (12.5g) granulated | 49 |

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
- Flour
- Starch that gelatinises with the hot water and sets into the dough's structure.
- Eggs
- Add structure and richness, binding the dough and helping it puff in the hot oil.
- Butter
- Adds fat for tenderness and richness in the dough.
- Water (milk)
- Hydrates the flour and creates steam that helps the doughnuts puff.
- Sugar
- Adds sweetness and helps the fried exterior brown.
The step that matters
Let the dough come off the sides before cooling. Cooking the flour paste until it pulls away from the pan drives off excess moisture and gelatinises the starch. If it stays wet, the dough will be too soft to hold shape and may absorb excess oil while frying.

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