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

What each ingredient does

Sour milk
Its acidity reacts with baking soda to produce gas that lightens the dough.
Baking soda
Reacts with the acid in sour milk to produce carbon dioxide, helping the doughnuts rise.
Sugar
Adds sweetness and helps the surface brown during frying.
Melted butter
Adds fat for a softer, richer texture.

The step that matters

Frying the spoonfuls in hot oil. If the oil is not hot enough, the doughnuts absorb excess oil and turn greasy; if it is too hot, the outside browns before the inside cooks through. Steady, moderate heat gives a golden crust and a cooked centre.
