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

What each ingredient does

Sweet potatoes
Soft, starchy base that the sugar glaze and flour coating cling to.
Brown sugar
Melts and thickens into a sticky glaze, adding sweetness and gloss.
Flour
Forms a thin coating that helps the outside crisp and brown when fried.
Butter
Fat that carries heat evenly and adds flavor and golden browning.
Drippings
Animal fat that adds savory flavor and promotes browning in the pan.

The step that matters

Boil the sugar and water until thick. Sugar syrup thickens as water evaporates and concentration rises. Too little boiling leaves a runny glaze that will not cling, while overboiling makes it hard and brittle once cooled.

Swap the sweet potato

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

  1. Arrowrootfits about as well
  2. Shallotfits about as well
  3. Sweet potatothe original
  4. Leekfits about as well

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