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 ↓
German Doughnuts
Ingredients
Directions
Make the dough
Boil the milk and pour it hot over the flour, mixing 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 board, turn the dough onto it, 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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the dough and whites, folded in, lighten its texture.
- Flour
- Provides the starch and gluten that give the dough its body and structure.
- Milk
- Hot milk moistens the flour and softens the dough.
- Butter
- Adds fat for richness and a tender crumb.
The step that matters
Frying in plenty of hot lard. The fat must be deep and hot enough to cook the dough quickly; if it is too cool, the doughnuts absorb grease and turn heavy and oily instead of browning evenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
