Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
German Doughnuts
Ingredients
Directions
Make the dough
Boil the milk and pour it hot over the flour; beat until smooth.
Let the mixture cool, then add the beaten egg yolks and mix well.
Fold in the beaten egg whites and add salt.
Add more flour until a soft dough forms.
Shape and fry
Flour your work surface, turn out the dough, and roll it into pieces as thick as your finger, shaping them into rings.
Fry the doughnuts in plenty of boiling lard until golden brown.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Forms the structure of the dough once it is mixed with the hot milk and more flour.
- Milk
- Adds moisture and, when boiled and poured over the flour, helps create a smooth dough.
- Eggs
- Yolks add richness and binding, while whites folded in lighten the dough's texture.
The step that matters
Let the mixture cool before adding the egg yolks. Hot mixture can scramble or cook the beaten egg yolks, which would leave lumps and weaken the dough's smooth, even texture.
