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

What each ingredient does

Sweet potatoes
Make up the bulk of the balls and give them a soft, starchy body.
Cream or milk
Adds moisture and richness, keeping the mash soft and smooth.
Butter
Adds fat and flavor to the mash, and helps the outside brown when frying.
Flour
Forms a thin coating that helps the outside brown and crisp in the fat.

The step that matters

Frying in hot butter until golden brown. If the butter is too hot, the outside browns and burns before the center heats through. If it is too cool, the balls absorb grease and turn heavy. Moderate, steady heat browns the flour coating evenly through the Maillard reaction.

Swap the sweet potato

How well each one fits the dish's main ingredients (cream, butter, flour):

  1. Leekfits better
  2. Arrowrootfits better
  3. Chivefits better
  4. Sweet potatothe original

Fit is the average pairing score against cream, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
