The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness, giving the dough a soft crumb and flavour.
- Sugar
- Adds sweetness and helps the doughnuts brown attractively when fried.
- Eggs
- Bind the dough and add structure and richness to the crumb.
- Flour
- Forms the structure of the dough, which must be stiff enough to roll and cut.
- Baking powder
- Releases gas that makes the doughnuts rise and turn light in texture.
- Sweet milk
- Provides moisture and liquid that hydrates the flour into dough.
The step that matters
Frying in hot oil. If the oil is too cool, doughnuts absorb excess oil and turn greasy; if too hot, the outside browns before the centre cooks through. Steady heat gives even golden colour and a light, cooked interior.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, milk, egg, flour):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against butter, sugar, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
