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, salt, and baking powder.
In a separate bowl, beat the eggs, then add the sugar, melted butter, milk, and vanilla.
Gradually mix in the dry ingredients until the dough is just stiff enough to handle.
Roll out the dough on a floured surface to ½ inch thick.
Fry and finish
Cut with a doughnut cutter and fry in deep hot lard until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the gluten network that gives the doughnuts their structure.
- Eggs
- Add structure and richness, helping the dough bind and set when fried.
- Baking powder
- Releases gas during cooking, helping the doughnuts rise and turn light.
- Sugar
- Adds sweetness and helps the surface brown during frying.
- Milk
- Supplies moisture that hydrates the flour and keeps the dough tender.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
The step that matters
Frying in deep hot lard until golden brown. Oil temperature controls both browning and cooking through. If the lard is too cool, the dough absorbs grease and turns heavy. If it is too hot, the outside browns before the centre cooks.
