Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Chocolate Doughnuts
Ingredients
Directions
Make the dough
Sift together the flour, baking powder, and salt.
Beat the eggs, then add the sugar, melted chocolate, butter, and milk.
Stir in the vanilla.
Add the sifted dry ingredients to form a medium dough.
Roll out the dough to ½ inch thick and cut out with a doughnut cutter.
Fry and finish
Fry the doughnuts in hot oil until golden brown.
Once cool, sprinkle with sugar.

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 structure and richness to the crumb.
- All-purpose flour
- Forms the main structure of the dough once it is mixed with liquid.
- Baking powder
- Releases gas that makes the doughnuts rise and turn lighter.
- Melted chocolate
- Adds chocolate flavour and colour to the dough.
- Sweet milk
- Adds moisture so the dough comes together softly.
The step that matters
Fry in hot oil until golden brown. If the oil is too cool, doughnuts absorb excess oil and turn greasy and heavy; if too hot, the outside browns before the centre cooks through.
“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.
