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

What each ingredient does

Mashed potato
Adds moisture and tenderness to the dough, keeping the doughnuts soft.
Eggs
Bind the dough and add structure as they set during frying.
Flour
Provides the main structure that holds the doughnut shape.
Baking powder
Releases gas that helps the doughnuts rise and lighten.
Shortening
Adds fat that tenderizes the dough and gives a softer crumb.
Sugar
Sweetens the dough and helps the surface brown during frying.

The step that matters

Fry in deep fat until golden brown. Oil that is too cool lets doughnuts soak up grease and turn heavy, while oil that is too hot browns the outside before the centre cooks. Steady, moderate heat gives an even golden crust and a fully cooked interior.

Swap the potato

How well each one fits the dish's main ingredients (sugar, egg, milk, nutmeg, cinnamon, flour):

  1. Sweet potatofits better
  2. Arrowrootfits better
  3. Parsnipfits better
  4. Potatothe original

Fit is the average pairing score against sugar, egg, milk, nutmeg, cinnamon, flour. Candidates are from the same food group and used in at least 100 recipes.
