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

What each ingredient does

Sweet potatoes
Provide the bulk and starchy body that holds the balls together.
Milk
Adds moisture and softness to the mashed potato paste.
Egg yolks
Bind the coating so bread crumbs stick and brown during frying.
Bread crumbs
Form a crisp, golden outer crust when fried.
Sugar
Adds sweetness that complements the sweet potato.

The step that matters

Cooling the paste before shaping. A warm, soft paste is sticky and hard to shape, and it can break apart or tear the coating. Letting it cool firms the starch so the balls hold their form through coating and frying.
