Why it works: Milk and flour 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 ↓
Plain Doughnuts
Ingredients
Directions
Make the dough
Combine sweet milk, sugar, salt, and beaten eggs in a bowl; stir well.
Add baking powder to the flour and mix into the wet ingredients until a soft dough forms.
Fry
Heat lard in a deep dish until hot.
Drop spoonfuls of dough the size of an English walnut into the hot lard.
Carefully turn the doughnuts until they are well browned.

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 richness and structure to the doughnuts.
- Baking powder
- Releases gas in the dough, helping the doughnuts rise and turn light.
- Flour
- Forms the soft dough structure that holds the doughnuts together while frying.
- Sugar
- Adds sweetness and helps the doughnuts brown in the hot fat.
- Sweet milk
- Provides moisture that hydrates the flour and keeps the dough soft.
The step that matters
Drop spoonfuls of dough into the hot lard. If the lard is not hot enough, the dough absorbs fat and turns greasy and heavy. Hot fat sets the outside quickly so the doughnut puffs and browns evenly.
