Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Bind the dough and add moisture, and they set firm when fried.
Baking powder
Releases gas that makes the doughnuts rise and lighten.
Rolled oats
Add chewy texture and body to the dough.
Brown sugar
Adds sweetness and moisture, and helps the surface brown while frying.
Butter
Adds fat for a tender crumb and richer flavor.
Flour
Builds structure so the dough holds its shape in hot fat.

The step that matters

Frying the dough in hot lard until golden brown. Hot fat sets the outside quickly and forms a crust. If the lard is too cool, the dough soaks up fat and turns greasy. If it is too hot, the outside browns before the centre cooks through.
