Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the dough; beaten whites lighten it and add airy structure.
- Baking powder
- Releases gas in the dough, helping the doughnuts rise and become light.
- Butter or lard
- Adds fat for tenderness and a richer mouthfeel in the dough.
- Sugar
- Sweetens the dough and helps the doughnuts brown when fried.
- Flour
- Provides the structure that holds the dough together when rolled and fried.
The step that matters
Fold in the beaten egg whites last. Folding gently keeps the whites' trapped air intact, so the dough stays light. Stirring vigorously deflates the foam and produces denser doughnuts.
