Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough that holds the doughnuts together.
- Egg
- Binds the dough and adds richness and structure.
- Butter
- Adds fat for tenderness and flavour in the dough.
- Baking powder
- Releases gas that makes the doughnuts rise and turn light.
- Castor sugar
- Sweetens the dough and helps the surface brown when fried.
The step that matters
Seal the edges before frying. If the edges are not pressed firmly, the jam can leak out during frying and the doughnuts can open up. A tight seal keeps the filling inside as the dough expands in hot fat.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
