Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baking powder
- Releases gas in the dough so the doughnuts rise and turn light.
- Flour
- Provides the structure that lets the dough hold its shape when rolled and cut.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Sugar
- Sweetens the dough and caramelises on the surface for a golden finish.
- Milk
- Provides the liquid that hydrates the flour and forms the dough.
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 it is too hot, the outside browns before the inside cooks through. Steady, moderate heat gives an even rise and a golden crust.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, sugar, butter, flour):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against milk, sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
