Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to add richness and tenderness to the dough.
- Egg
- Adds structure and richness, binding the creamed mixture together.
- All-purpose flour
- Forms the main structure of the dough once moistened.
- Royal baking powder
- Releases gas during frying, helping the doughnuts rise and turn light.
- Milk
- Hydrates the flour to form a soft dough.
The step that matters
Fry in plenty of hot lard until light brown. Frying in enough hot fat keeps the oil temperature steady so the dough cooks through and absorbs little grease. Oil that is too cool makes doughnuts heavy and greasy, while oil that is too hot browns the outside before the inside is cooked.
“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.
