Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

All-purpose flour
Provides the structure that holds the dough together after frying.
Baking powder
Releases gas as it reacts, making the doughnuts rise and turn light.
Granulated sugar
Adds sweetness and helps the golden brown colour develop during frying.
Milk
Adds moisture so the flour hydrates into a smooth, workable dough.
Melted butter
Adds fat, which tenderises the crumb and adds richness.
Egg
Binds the dough and adds structure and richness.

The step that matters

Frying in boiling lard or suet. If the fat is not hot enough, doughnuts absorb excess oil and turn greasy and heavy. If it is too hot, the outside browns before the centre cooks through. Steady heat gives an even, golden result.
